Titanium alloy for manufacturing automatic rifle

The strength of titanium, titanium tensile strength up to 180kg/mm2. Some of the strength of the steel is higher than that of titanium alloy, but the titanium alloy than strength (tensile strength and density ratio) was more than the high quality steel. Titanium alloy with heat resistant strength, low temperature toughness and fracture toughness is good, so it is much used for aircraft engine parts and rocket, missile structure. Titanium alloy can also be used as a fuel and oxidizer tank and high pressure vessel. Now has a titanium alloy for manufacturing automatic rifle, the launch tube of mortar base plate and recoilless gun. In the oil industry titanium coil mainly for various vessel, reactor, heat exchanger, distillation tower, pipe, pump and valve etc.. Titanium can be used as electrode and a power station condenser and environmental pollution control device. Titanium nickel shape memory alloy has been widely used in instruments. In the medical treatment, titanium can be used as artificial bones and various utensils. Titanium or steelmaking deoxidizer and stainless steel and alloy steel components. Titanium dioxide pigment and paint is a good raw material. Titanium carbide, carbon (hydrogen) is a new type of titanium carbide materials. Titanium nitride color close to gold, widely used in decoration. Titanium and titanium alloys used in large quantities for the aviation industry, "space metal" known; in addition, is widely used in the shipbuilding industry, chemical industry, titanium sheet machinery parts manufacturing, telecommunications equipment, hard alloy, etc.. In addition, because the titanium alloy also has good compatibility with the human body, so the titanium alloy can also be used for artificial bone. The corrosion resistance of titanium zirconium nitrate and hydrogen titanium zirconium oxide is a kind of application in the atomic energy industry and used as a corrosion resistant chemical materials under high temperature and pressure, but in the lively after sodium solution. Then, the titanium hydroxide solution added live wave zirconium nitrate solution, will find that to shut sb. titanium zirconium nitrate. As you can see, there are the obvious layered graph, the above is zirconium nitrate, below is the titanium hydroxide. We know, titanium hydroxide is less than the density of zirconium nitrate, but can still maintain the obvious stratification, and zirconium nitrate stay in the upper, which proves that the corrosion resistance of titanium. According to the experiment, titanium into the ocean of annual 20~50 won't be corroded.

Titanium alloy plate prices

Titanium alloy plate at the current price trend is not particularly good, the recent domestic titanium plate market demand are relatively sluggish, prices remain low stage, the short term, the market price will be difficult to recover, the current 2mm pure titanium plate price in the 105-115 yuan / kg (15.51-16.99 dollars / kg). Titanium is a metallic titanium coil element, grey, atomic number 22, relative atomic mass 47.87. Combustion in nitrogen, high melting point. Blunt titanium and titanium based alloy is a structure with new materials, mainly for the aerospace industry and marine industry.
Titanium density of 4.506-4.516 g / cubic centimeters (20 DEG C), higher than that of aluminum and iron, copper, nickel below. But in the first than the strength of the metal, is 3 times of stainless steel, is the aluminum alloy [colored business: 1.3 times of the aluminum alloy plate]. The melting point of 1668 - 4 DEG C, the latent heat of fusion of 3.7-5.0 kcal / atom, the boiling point of 3260 plus or minus 20 DEG C, the latent heat of vaporization of 102.5-112.5 kcal / atom, the critical Aerospace titanium castings temperature of 4350 DEG C, the critical pressure of 1130 atm. Poor thermal conductivity and conductive properties of titanium, similar to or slightly lower than stainless steel, titanium superconductor, superconducting critical temperature of pure titanium 0.38-0.4K. At 25 DEG C, titanium heat capacity is 0.126 cards / atom and degree, 1149 card / molecular enthalpy, entropy is 7.33 cards / atom and degree, metal titanium is paramagnetic material, permeability is 1.00004. Titanium has plasticity, extending high pure titanium rate can reach 50-60%, section shrinkage rate of 70-80%, but low strength, not as structure material. Titanium in the presence of impurities, a great influence on the mechanical properties, especially the interstitial impurities (oxygen, nitrogen, carbon) can greatly improve the strength of titanium, significantly reduced its plastic. Good mechanical properties with titanium as a structural material, through strict control of the impurity content is appropriate and adding alloy elements and to achieve.

Titanium alloy technology

Titanium alloy is with titanium alloy added other elements. There are two kinds ofdifferent titanium crystal: 882 DEG C for close packed six party structure titanium, 882 DEG C beta titanium as the body centered cubic.

Alloy elements according to their influence on the phase transition temperature can be divided into three categories:

A stable alpha phase, increase the titanium bicycle frames phase transition temperature of the element as thealpha stable elements, aluminum, carbon, oxygen and nitrogen. The aluminum is the main alloy titanium alloy elements, it is to reduce the quality of the alloy at room temperature and high temperature strength, elastic modulus, increase proportion has obvious effect.

The stability of beta phase, reduce the transition titanium bicycle part temperature element for beta stableelements, can divide again isomorphous and eutectoid type two. The application oftitanium alloy products, the former are molybdenum, niobium, vanadium, manganese,chromium; the latter are copper, iron, silicon, etc..

The phase transition temperature has little effect on the element as the neutralelement, a zirconium, tin etc.. Oxygen, nitrogen, carbon and hydrogen are the mainimpurities in titanium alloy. Oxygen and nitrogen has greater solubility in the alphaphase, there are significant strengthening effect of titanium alloy, but the plasticity decreased. Usually the provisions of oxygen and nitrogen in titanium content in 0.15 ~0.2% and 0.04 ~ 0.05% below. The solubility of hydrogen in the alpha phase is very small, too much dissolved in titanium alloy hydride hydrogen will be produced, the alloy brittle. Usually in titanium alloy hydrogen content of 0.015% control in the following. Dissolved hydrogen in titanium is reversible, can be used to remove thevacuum annealing.

The reaction will be intense until the titanium sponge plant reactants consumed

Thereafter, as long as there is enough in chlorine, the reaction will be intense until the reactants consumed. However, if there is enough water in the chlorine gas, the titanium tetrachloride reacts with water to produce hydrogen will be titanium, which is a non-volatile substance, aerospace investment casting and become firmly attached to the surface of a film of titanium, this reaction is extremely stable reaction, and the surface film in a titanium sponge plant wet chlorine is extremely stable. Thus Titanium has excellent corrosion resistance in wet chlorine, chlorine gas is closely related to its stability in water content. Titanium and titanium alloys in the Titanium castings gasoline, toluene, phenol, formaldehyde, trichloroethane, acetic acid, citric acid, ethyl monochloroacetate, etc. having a high Chun corrosion resistance, but in the titanium sponge plant case of the boiling point and not inflated, the titanium sponge plant mass fraction of less than 25% will be subject to severe corrosion of formic acid, acetic anhydride in a titanium sponge plant solution containing titanium severely not only general corrosion, pitting and will titanium casting process produce, for a number of complex organic medium in contact with the organic synthesis process, as in production of propylene oxide, phenol, acetone, acetic acid and other chlorinated chemical medium corrosion resistance of titanium and titanium alloy structural materials other than stainless steel sun.

Affected companies choose slag based on customer orders to schedule production

Some Chinese companies have discontinued slag and advance into the Chinese New Year holiday state. Given the current trading price of the product is too low, the majority of companies have aerospace investment castings presented a loss. Affected companies choose slag based on customer orders to schedule production, lower overall industry operating rates. Meanwhile, the annual market performance is more sluggish domestic acid soluble chloride slag and slag showed a state of oversupply . According to the Swiss road network is understood that there are some domestic enterprises chloride slag small amount of inventory , and the acid-soluble slag inventory is titanium alloy pump vrelatively high. In addition, due to the widespread downstream buyers to delay the payment date , the current domestic enterprises slag poor liquidity and high financial costs.State Reserve policy affected by early December , some titanium sponge titanium sponge enterprises to improve the sales price.According to a Titanium alloy sheets company official said titanium sponge , although the state had acquired a certain size , but because of the large amount of inventory on the market earlier , coupled with the downstream demand is not ideal , so despite favorable policies.

Although titanium sponge material in the Second

Although titanium material in the Second was discovered seven years ago , but due to refining process was not easy ( titanium sponge is very easy to combine with oxygen ) , scientists have been unable to titanium alloy be refined into useful substances metals. Until 1938 , DuPont developed a new way to extract , plus magnesium reduction method, the red and gold reserves in the ground ore , after chlorination, plus magnesium , restore titanium alloy pump it and become a titanium sponge titanium, to a ninety-four three years , DuPont began producing a large number of titanium sponge metal products.Titanium is a metallic chemical element , because the refining process is not easy, and less expensive titanium sponge production , it is only used in the early titanium sponge science , marine science and other high-tech titanium sheet science and energy development . And daily necessities are to begin in applied to the titanium sponge .We can be a magnet placed on the table , then leaned over the frame , if it is not generating the magnetic response of titanium frames . Also check its hinge , titanium glasses are placed two plastic or metal liner in the hinge , in addition , because of different metals with different electrical conductivity , so with conductive index can be measured whether the titanium metal.

Titanium sponge plant extract purity methods

Secondary smelting produce consumable content of impurities TA2 pure milled raw material ingot Table relationship , which is the average of 100 titanium ingots . As can be seen from the table, iron , titanium ingot and the nitrogen concentration of the titanium sponge plant has not changed , the purification effect of sky ; silicon, carbon and oxygen titanium sponge increased slightly , and no purification effect, but in the smelting process is increased impurity contamination volume ; Lee hydrogen chloride purification obvious effect , do not hold the product in a reduced number of chlorine and level . It also shows that the main role of vacuum distillation . Both the total amount of impurities from the point of view , slightly lower titanium sheet metal than the titanium ingot of titanium sponge plant impurities, by lowering the melting sponge drink chlorine , and slightly increases the oxygen and other impurities. In short , a slight increase in the purity of titanium , but it remains in a substantially horizontal magnitude .State Reserve policy affected by early December , some titanium sponge plant titanium sponge enterprises to improve the sales price,so despite favorable policies , but did not titanium alloy plates change the current market downturn titanium sponge plant trend.Some titanium sponge plant enterprises raise product prices , but signs of recovery as the market did not like before . Since downstream firms reflect flat, high offer titanium sponge plant enterprises become castles in the air , and soon dropped back to previous levels. And during the bidding , some companies did not follow the big companies with price increases.

Titanium sponge powder future challenges

Recently, titanium suppliers located in the industrial parks of titanium supplier Co., workers are annual tons of titanium sponge powder production line busy. This is currently the only Titanium casting of titanium sponge powder production with advanced core technology that enables the whole process of production of titanium sponge powder titanium supplier manufacturers. Titanium sponge powder is the basic raw material for the production of titanium and titanium alloy products. Titanium and titanium alloy for superior performance, are widely used in aviation, aerospace, ships, petrochemicals, medical titanium supplier and other fields, known as the "21st century material" in the context of economic globalization, vendor selection in the production and operation of enterprises role changes. Titanium sponge powder selection is no longer just a single business function, and has gradually become a strategic decision. When titanium supplier selection has gradually titanium coil become a corporate strategic decision-making, companies can no longer choose the traditional lowest quality as the main criteria for suppliers, but must establish a rigorous and comprehensive standards. In this case, how to select and manage suppliers, many companies have become an urgent need to face and solve the problem.

Titanium sponge and impact on the future development of the market

In a recent meeting of experts of titanium and titanium alloy Thirteenth National Symposium confirmed: From the perspective of cities across the country , in addition to outside Luoyang , China does not have a region or city has a complete industrial chain of titanium , however Luoyang City can titanium sponge production of titanium ingots , but Titanium castings also can produce titanium ingots into titanium mill until the production of titanium equipment. China is currently the only city which has a complete industrial chain of titanium - " Titanium City ."It is understood that , after 40 years of development, China has become after the United States , Japan, Russia and the fourth has a complete industrial system titanium sponge titanium country . Experts, a complete industrial chain of titanium sponge , the main components products are: titanium sponge ( base material ) - titanium cast ( casting ) , semi-finished products , titanium processing material ( sheet, strip, tube , rod ) - titanium parts and titanium equipment manufacture. Although the country as a whole , China's titanium industry with complete system , but on a city or a region, titanium foundry currently has only met the requirement of Luoyang whole industry chain.Titanium sponge as materials research and application of marine focal point, located in Luoyang, China Shipbuilding Industry Corporation Institute is one of the seven two five research institutes to carry out a few handful of domestic titanium systems research , applied research in titanium areas represent the national level.

Titanium sponge recent attention by the market

I want to let more people know about titanium plate  titanium know , the use of titanium , titanium had to start from the origin , and the depth into the room , go slowly so that people know the truth about titanium .

Titanium sponge production and origin

German mineralogist and analytical chemist Klaproth in the analysis region of Hungary Bowie Nick red rutile production , Chen found mine looks like Manasseh , after comparative studies, titanium sponge knows the difference between the main ingredient similar, but Manasseh Chen ore containing iron . Klaproth convinced that this is a new metal oxide , and curiously named the new element to this "Titanium" ( Ti ) , the name refers to a Greek myth : that titanium companies heaven and earth son called first generation "Too Dan Adams " (Titans), it is the legendary Titan , from , Ti titanium has become a symbol . 1849 German chemist Weiler with potassium and fluorine potassium titanate of heat , a system of impure metal titanium. Smelting Titanium sheet is present , first through a series of titanium ore processed into titanium tetrachloride, and then magnesium or sodium reduction in an inert gas to produce spongy titanium is titanium sponge .

The principle of production of titanium sponge

Titanium sponge is a basic link of making titanium ingot and titanium indispensable and intermediate products, refined titanium sponge, high cost of titanium sponge ingot,restricted the development of titanium industry, affecting a wide range of application of titanium. I GB sponge titanium by hardness is divided into 6 grades, titanium sponge isloose and porous sponge, high surface area, more lively, easy oxidation. Titanium sponge is not easy to long-term storage. According to regulations, sponge titanium alloy pump grade 0 -5 total of six grades (quality, purity%) is generally 99.1 ~ 99.7, impurity elements (% quality) a total of 0.3 ~ 0.9, impurity elements oxygen (% quality) is 0.06 ~0.30, hardness (HB) of 100 to 200.

Production technology and method of titanium sponge

Method the sponge metal titanium produced metal thermal reduction. % purity (quality) is generally 99.1 ~ 99.7. Impurity elements% (quality) a total of 0.3 ~ 0.9, impurity elements oxygen% (mass) of 0.06 ~ 0.20, hardness (HB) ranged from 100 to 157, according to the different purity of WHTiO to MHTi4 five grades. As the main raw material for the preparation of industrial titanium alloys. Sponge titanium production is the basic link of titanium industry, it is titanium, titanium powder and other raw materials of titanium sponge  The ilmenite becomes four titanium sponge, then put in a sealed stainless steel tank, filled with argon, making them react with the magnesium metal, get "titanium sponge". The porous, "sponge titanium" is not used directly, also must put them in an electric furnace melting into a liquid, in order to cast titanium alloy plates  Molten salt chlorination process is developed in the former Soviet Union in twentieth Century 60, method for production of four titanium sponge, the raw material characteristics of this method is applicable not only to the former Soviet Union (titanium slag containing CaO+MgO about 6%), the furnace production capacity of 20 t/m2 ~25 t/m2 four titanium chloride, molten salt section area of 6m2. Large molten salt Nissan four Titanium alloy sheet chloride was 120 t~150 T, formerly the rectangular furnace, the furnace for the round, round molten salt chlorination furnace size of Φ 5 m × 8.5 m, inner diameter is 2.76 m, the rectangle is 4.5 m × 3.5 m × 8.5 M. No dead angle circular furnace, furnace body strength increase, 3 years 1 times than the rectangular furnace overhaul, nearly 1 times the service life extension. Molten salt chlorination can use a variety of rich titanium material, in addition to titanium slag containing calcium magnesium, is now widely used by red ilmenite (Fe2O3 3TiO2) Ti slag smelting (TiO2 87%~91%), can also use the rutile.

The nature of titanium sponge, packaging and storage

Titanium is a corrosion-resistant metal, but absolutely no oxidation, no corrosive substance is not there. Titanium oxide does not, particularly at high temperatures, easily combines with oxygen, but it is very dense oxide, oxygen can be prevented from further erosion. Titanium sponge is a loose porous sponge-like, large surface area, more lively. The larger the surface area, the contact surface with the air, the higher the activity, easy and gas, water reacts easily oxidized. The titanium oxide is an impurity element, oxygen content exceeded, you can not use titanium sponge, can only be scrapped. Fine powders of titanium sponge in the heat, may cause a fire in case of fire or contact with oxidants time, also can burn in carbon dioxide or nitrogen. Only argon and helium burning titanium powder can only be controlled, according to the combustion science we know, in the processing and handling of metal powders, usually produce a dust cloud, the cloud of dust mixed with air if the right proportion, reaching the limits of explosion inside, outside in case of fire, sparking, static fire can ignite the metal dust. Titanium sponge packaging: titanium sponge per barrel (piece) net weight 70kg ~ 250kg packing, galvanized iron drums, barrels lined with PVC film bag with Uncovery sealed lid junction with the barrel body should there can identify the identity of the packaging is intact. Generally are now 200kg barrel. After the product packaging, drums evacuated, filled with argon. Products should be stored in dry warehouse, shall open dumps or with acid, alkali and other corrosive materials mix. Product transportation should be handled with care to prevent moisture and seals collision damage. Based on the information available, titanium sponge is still no long-term storage experience. Depending on the nature of the experience of titanium sponge and titanium processing of various titanium plate must pick with storage period no longer than one year. We reserve system was stored over titanium sponge. In the 1970s, because of our lack of understanding of the nature of titanium sponge, had received a number of titanium sponge, a bucket was 100kg, large grain size are more now. This batch of titanium sponge receives less than six months, some experts pointed out that, not long-term storage of titanium sponge, titanium sponge National Bureau soon the library, from the factory for the titanium ingot processing and storage, the storage period before and after less than a year. So far as we, the long-term storage of titanium sponge is also inexperienced.

The development of scene of titanium sponge

In the production process of titanium to toxic chemical medium chlorine (chemical weapons in World War II oh) and noble metal magnesium, and the reaction process requires a lot of energy, which is why titanium expensive. The smelting process oftitanium is not to be used for production, because it is porous shape, resembling asponge, called titanium sponge, titanium alloy pump will be placed in vacuum consumable electrode arc furnace smelting titanium ingots, plates, rods, tubes and for other formsof titanium production. Titanium is rich in resources, mineral resources are relatively concentrated, converted into TiO2 total reserves of 90 million tons, is the first in the world. The main distribution of titanium ore, the reserves accounted for 35% of the world's total reserves. However, compared with the world's major mineral producing area, natural Jin Hongshi (TiO2) less resources, easy exploitation of placer less.Titanium, titanium iron ore more symbiotic, smelting high initial cost. Here also need to refer to a story, the original iron and steel smelting steel slag after stacked in a cornerfor a long time to climb, we did not find this kind of slag inside unexpectedly containprecious metal titanium. Later proposed to buy our slag, concrete truth that make our national attention on the Panzhihua Iron and steel slag, of course rejected japan.

titanium sponge industry started in twentieth Century 1954 50 years, non-ferrous metalbegan to research on the preparation of sponge titanium, titanium metal as thestrategy on the 12 year development plan, in 1958 in the industrial test of spongetitanium, founded the first titanium sponge production workshop, at the same time,non-ferrous metal processing plant was established the first titanium processing material trial production workshop. Before and after 1980, the titanium spongeproduction reached 2800 tons, but because most of them were lack of knowledge on the titanium, titanium pumps high prices also limit the application of titanium, titanium processing material production is only 200 tons, titanium industry in trouble.

Sponge titanium and titanium sponge powder is mainly used in which a few respects

Titanium sponge is the basic raw material for the production of refined metal titanium. The further refinement of titanium sponge, can be made of titanium ingots, titanium bar, titanium metal material. The sponge titanium by mechanical grinding, can produce titanium powder. Titanium powder as the coating material, is widely used for surface treatment processing machinery and equipment, electronics and precision instruments, and other metal can be synthesized titanium alloy powder etc.. The concept of another branch of titanium sponge titanium production on the stage, the titanium dioxide concept stocks, has become the focus of attention of the market. In the Western materials trading producing titanium sponge lead, also have the extraordinary performance. It is reported, authorities have to consider the introduction of policies, preparing for the implementation of access management of titanium sponge industry, without the technical characteristics obviously or duplicate construction projects during the 12th Five Year Plan period, will not be authorized. Sponge titanium production is the basic link of titanium industry, it is titanium, titanium powder and other raw materials of titanium component. The ilmenite becomes four titanium chloride, then put in a sealed stainless steel tank, filled with argon, making them react with the magnesium metal, get "titanium sponge". The porous, "sponge titanium" is not used directly, also must put them in an electric furnace melting into a liquid, in order to cast titanium ingot. Titanium industry chain from upstream rutile titanium concentrate, titanium,titanium sponge, to quote product of titanium, can more clearly see is currently occurring from the upstream industry chain and cost push price type promotion. Titanium dioxide is thought to be the world's best performance of a white pigment, widely used in paints, plastics, paper, printing ink, chemical fiber, rubber, cosmetics industry.

The titanium concentrate prices have hit a record and maintain the basic stability of titanium plate and titanium dioxide, shipment is basic and normal price increase, domestic titanium currently costs more difficult, suffered greater cost pressure. What is the titanium sponge? It is the sponge titanium production of metal thermal reduction method. % purity (quality) is generally 99.1 ~ 99.7. Impurity elements% (quality) a total of 0.3 ~ 0.9, impurity elements oxygen% (mass) of 0.06 ~ 0.20, hardness (HB) ranged from 100 to 157, according to the different purity of WHTiO to MHTi4 five grades. As the main raw material for the preparation of industrial titanium alloys. Sponge titanium production is the basic link of titanium industry, it is titanium, titanium powder and other raw materials of titanium component. The ilmenite becomes four titanium chloride, then put in a sealed stainless steel tank, filled with argon, making them react with the magnesium metal, get "titanium sponge". The porous, "sponge titanium" is not used directly, also must put them in an electric furnace melting into a liquid, in order to cast titanium ingot. From the discovery of Ti to first prepare the metal titanium relatively pure has experienced 120 years of history. By the lab for the first time to obtain the pure titanium to the first industrial production, has spent the past 40 years. Many researchers do a lot of exploration, from failed again and again, to produce titanium sponge tonnage.

Four titanium chloride is mainly used for the production of sponge titanium, titanium dioxide and titanium trichloride. Many of its preparation method, mainly in boiling chloride fused salt chlorination furnace, and 3 methods of chloride. Boiling chlorination is the main method of the current production of four titanium chloride (China, Japan, America use), followed by the molten salt chlorination (the CIS countries), and the shaft chloride has been eliminated. Boiling chlorination is generally low in calcium and magnesium content of high grade titanium rich material as raw material, and molten salt chlorination could use the materials containing high contents of calcium and magnesium.‍
