True and false of titanium sponge rods how to judge

Now, the application of titanium alloy rods is more and more widely, with the continuous development of society, some people in order to covet interests, produce fake of titanium alloy rods, shoddy, sales to the customer, make a lot of damage to customer interests, therefore we need to know how to judge the true and false of titanium alloy rods, avoid buying home of titanium alloy rods. Below, will introduce you to judge true and false of titanium alloy rods.

Judge true and false of Titanium Graphite Mold Casting rods the simplest method is the weigh in hand, if feel lighter, so may be pure titanium rod, this is the difference between titanium and the titanium frame is one of the most simple way.Because when the proportion of Sunrui titanium golf clubs frame is about 8.9 g/cm3, and the proportion of pure titanium frame is 4.5 g/cm3, titanium rod weight equal to half of the alloy frame. Weld mark as "steps"; Spot welding, the welding of titanium alloy rods investigate the nasal stem and the weld of box, and pure titanium material welding for anaerobic touch welding. Weld mark as "slope", this is the difference between titanium and titanium frame, titanium and non-uniform titanium frame of one of the useful way.

So, to see if there are any more gaskets, hinge place is the difference between pure titanium rods of a more effective method.

Some common titanium products

Titanium washing tower is installed on the incinerator for processing very low levels of radioactive waste . The device has been put into use in 1973 , titanium pumps the operating temperature of 160 a 250 ℃. According to the results of the last inspection , the titanium device is not found evidence of corrosion .
    Recently, the scrubber waste heat boiler in a pulp mill on the uniforms of water have been used titanium plates . 3l6L originally designed using stainless steel, 1979 replaced with titanium plates dehydrating it . These dehydrated plate for 120 ℃, pH value of the water cycle water cycle 3-4 aggregate a large number of hydrogen sulfide and sulfur dioxide gas . Using the results are quite satisfactory , and therefore , the plant plans to other scrubber systems all use titanium plate dehydration .
    Titanium is also being used in addition to the ttitanium valve need from the scrubber wash hydrogen chloride , and have achieved good results . The column was washed at a temperature of 140 ℃, pH value of 10-11 , a sodium hydroxide solution after two cycles of operation , the frame and mesh of titanium are not corroded . Therefore , the plant engineering have made handsome would rather invest in titanium does not require maintenance , rather than using plastic or fiber- reinforced plastic titanium pump Branch (FRP).

Titanium tube heat transfer efficiency to beat rivals

  From the viewpoint of heat transfer efficiency, we find that the titanium alloy pipes with other tubing (e.g., copper-nickel alloy) match. High strength titanium and high Titanium Casting Manufacturer impact resistance allowable turbidity of seawater with high flow rates and titanium alloys have a high temperature corrosion resistance, titanium-nickel alloy than copper heat exchanger 60 a weight reduction of 70%, the their overall heat transfer efficiency is roughly the same.
     Due to the longer life of the titanium tube structure to offset one-time investment, in terms of economic efficiency is also something else. And because of the speed for the entire period in the life of the tube can reduce downtime, thus also receive an additional character. With the growth and expansion of the use of titanium production, the cost and availability of titanium improved. aerospace investment castings Titanium also with 317L stainless steel, Monel alloy 400 and Hastelloy C-276 to compete. It is predicted that in the middle with seawater cooled heat exchangers, finned whole rolled titanium tube will completely replace copper-based alloy tube.

13 years of industry subsidence trough titanium sponge titanium industry-wide losses

‍013 years of industry subsidence trough titanium sponge titanium industry-wide losses
December 2013 Titanium Market Review

This month perovskite thin market , aerospace investment casting traders expect downstream manufacturers can then take advantage of the phenomenon appears Dongchu stocking raise ore price , but on the downstream market before the Spring Festival perovskite save more bearish attitude , procurement were significantly hesitate Dongchu stocking phenomenon later later in the future. And near the end , the buyer Yakuan serious , some businesses are willing to boost sales of low-cost shipping return cash flow. Imported ore more or less supported by the outer disk costs , limited the decline , while the Panzhihua region ore price confusion, repeated exposure to small factory prices low.
New Year's Eve , 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 presented a loss. Affected companies choose slag based on customer orders to schedule production, lower overall industry operating rates. Meanwhile, the 2013 annual market performance is more sluggish domestic acid soluble chloride slag and slag showed a state of oversupply . titanium bicycle frames 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 relatively 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 , the highest price of 0 # titanium sponge over 52,000 yuan / ton. However, due to the downstream repercussions dull , no corporate procurement , the price has become a castle in the air , then quickly dropped to 4.9 yuan to 50,000 yuan / ton price . Titanium Casting Golf Heads According to a 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 , but did not change the current market downturn titanium sponge trend. As of the end of December 2013 , the domestic price of titanium sponge is only 1000 yuan / ton symbolically raised , and the actual volume is still maintained at a low level. In addition, the purchasing and storage operations led some companies to obtain the melting orders for titanium ingot processing enterprises inject some vitality. However, due to the downstream market remains in the doldrums , making the purchasing and storage policies benefiting a narrow face .
Subsidence trough titanium sponge titanium industry wide losses
Throughout 2013 , we can say the whole titanium industry has experienced a very difficult year , the most obvious manifestation is the price of all products falling almost all year . Among them, the import price of titanium dropped from the beginning of 2300 yuan / ton to the end of 1600 yuan / ton , down 30% ; 90 slag fell from the beginning of 8000 yuan / ton to 5,800 yuan to 6,000 yuan / ton , down more than 25% ; 0 # titanium sponge price from 66,000 yuan in early / ton decreased to 4.9 yuan to 50,000 yuan / ton, down about 25 %. Currently, the price of titanium sponge was significantly lower than its cost , the titanium bicycle part companies are operating at a loss situation, few companies have been forced to stop production .
Affected by the downturn in the overall economic environment in 2013, non-ferrous metals industry generally face greater difficulties. Under this background , the titanium industry is not immune . Downstream products unsalable forcing down prices upstream manufacturers of raw materials, while the upstream companies had gradually compromise, bottom- price surges gradually spread to the entire industry . In addition, various manufacturers feel uncomfortable phenomenon is the decline in prices can not be picked up in exchange for sales , customer purchases always in tepid state.

‍From the Swiss road network information

‍From the Swiss road network information currently available to view, in 2013 the total output of the industry is in a state of slight growth , the growth rate of more than between 5 % to 8 % growth in individual sectors stagnated . The annual average price is lower than in 2012 , which resulted titanium bicycle frames in the majority of enterprise revenue is lower than last year. Meanwhile, the downstream product prices first drop, after drop upstream raw material prices , thus causing downstream enterprises to bear more pressure . Tension downstream enterprise funds , making widespread payment defaults occur within the industry . The spread of this case bottom , making 2013 the individual enterprise funds are plagued by varying degrees .
At the end of 2012 when the annual plan to do , the industry was optimistic the market will improve in 2013 . This also leads to a certain extent, when enterprises are facing a downturn , the difficulties are not sufficient to prepare . Preliminary statistics from the current point of view , in 2013 the national production of titanium sponge is still modest growth , the supply is higher than demand for titanium processing industry. When the increase in business inventories , the usual coping should be controlled in order to maintain profit margins yield . But in fact, some companies fail to make adjustments in a timely manner , yields rise, Titanium Artificial Joint not fall , resulting in a large number of products unmarketable. The product unsalable lead enterprise funds tight , which prompted enterprises to turn to loans from financial institutions . Although you can ease the financial pressure in the short term , but also to bring greater financial costs , potentially increasing the burden on enterprises. In order to repay the loan , some companies phased cheap Paohuo return funds, further exacerbating the decline in product prices , which thus caught in a vicious cycle .
After December 2013 the State Reserve policy began , some titanium sponge enterprises raise product prices , but signs of recovery as the market did not like before . Since downstream firms reflect flat, high offer titanium sponge 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, which is also reflected in the side after a long titanium sponge industry expansion has weakened the influence of leading enterprises . Manufacturers unsalable inventory into titanium sponge titanium ingots after , although the pressure of titanium sponge enterprises get some relief , but we also worry about the future market demand may Titanium Golf Club Heads be overdrawn in advance , thus making the market more difficult in 2014.

titanium sponge plant

From a historical perspective titanium widely adopted

Historically, the use of titanium for two main titanium sponge plant reasons: the structure of materials with properties; resistant to corrosion. Because titanium combination of high strength, low specific gravity, good toughness and has good resistance to smallpox labor performance, etc., so you can design excellent performance components. In many or most cases, the titanium can be obtained after annealing these properties, which greatly facilitates manufacturing. Chloride and titanium oxide dielectric, since the passivation layer is formed on the surface, thereby having a very good corrosion resistance, can be the same as the corrosion-resistant metal is set. 
     The rise in the titanium industry's first 20 years, titanium is mainly used in aviation and aerospace industry. Titanium production is unstable in 198t years ago, titanium precision casting from about 1970, sales of titanium in the civilian industrial market began to rise, and relatively stable to 1981 civilian industrial markets titanium consumption of industrial production accounts for about 20 a 30%. Civilian industrial market volatility than small aviation and aerospace industry, which for the stable development of the industry in Chin provided favorable conditions.

Titanium sponge plant and chloride furnace

In the design of titanium sponge plant , the general use of open type or closed type three-phase arc furnace smelting of titanium slag. The former low thermal efficiency, high energy consumption, poor labor conditions and low yield.

  Chloride furnace has several types, vertical furnace, a sieve plate fluidized chlorination furnace, no sieve fluidized chlorination furnace and molten salt chlorinator etc.. aerospace castings

  Furnace type selection depends on the grade of raw materials, harmful impurities (Mg, CA), the content of raw materials, energy consumption and metal yield.

  Calcium and magnesium chloride containing fewer impurities titanium raw material, selects the fluidizing chlorination furnace. Molten salt chlorination device is an effective device for processing low grade and high content of calcium and magnesium rich titanium sponge material, but there must be effective facilities disposal or recycling of waste salt.

Four refining process of crude titanium tetrachloride of titanium sponge

Coarse titanium tetrachloride refining process by four vanadium removal and separation of four chlorinated silicon two system components. Four refining process for coarse titanium tetrachloride in the production of titanium sponge , and the two system. In addition to the four chlorinated silicon technology is not suitable for the production of titanium dioxide.

  Anhydrous magnesium chloride is a good raw material for magnesium smelting, recycling is an important measure to reduce the cost of production of sponge titanium. Production of  titanium sponge ( aerospace castings )by Kroll Process Factory, are equipped with anhydrous magnesium chloride electrolysis workshop, recovery of metal magnesium and chlorine.

Early sponge titanium production

Chlorination process choice depends on the TiO2 content in raw material. Many western countries to natural rutile (95% ~ 98%TiO2) and high-grade artificial rutile as raw material, the process is simple, chloride, low material consumption, high utilization rate of chlorine and simple equipment system.

  China titanium slag as raw material, the content of impurity, high material consumption, low utilization rate of chlorine, equipment system is huge.  Titanium sponge production early, some factory used shaft EAF process.

Production of sponge titanium materials

Magnesium reduction process is composed of process of titanium concentrate or titanium rich material, refined, chloride reduction distillation and broken packing etc..

  China lack of natural rutile, titanium sponge production of raw materials can only be based on by the rich titanium material titanium iron enrichment.

  Rich titanium material is referred to as the titanium slag and rutile in commodities. The production of artificial rutile titanium slag and process had electric method, hydrochloric acid direct decomposition of titanium concentrate, combined dressing and smelting of dilute hydrochloric acid leaching method and reductive leaching pressure leaching method, pre oxidation fluidized acid etc..

  In the two method, reduction of dose per tonne of titanium sponge production required, sodium nearly twice higher than magnesium, sodium price must be less than half the magnesium, sodium reduction method have the competitiveness.

Comparison method for industrial production of titanium sponge

Sponge titanium production quantity by Kroll, accounts for more than a total of 80% world production of sponge titanium. Klau Apha is the advantage of the purification by distillation of the products of good quality, chlorine content is low, in favor of processing smelting.

  Chlorine content and gas Hunter method of product impurities, processing and smelting difficult, but less investment, finished product size of titanium sponge alloy for small.

  Easy preparation, powder metallurgy.

The production of titanium sponge industry,Kroll Process

The reduction reaction is completed in a Klau Apha reactor made of steel in. About 50% of magnesium and magnesium chloride containing the reduction product, three kinds of methods available vacuum distillation, purification of helium gas and wet purification treatment reduction product, made of titanium sponge weight or grain.

  Three purification process of reduction products are broken system to adapt with it, cooperate with each method made size to meet the requirements of the commercial titanium sponge.

  At the beginning of the 90's, have been useful to replace his potential of vacuum distillation method. In the reduction process, a by-product of anhydrous magnesium chloride and sent to the recycling of magnesium electrolysis workshop, magnesium and chlorine.

The production of titanium sponge industry,Hunt's method

The main process , Huntfa crude sodium metal with filter screen or a filter for fine purification method of sodium. In the reactor, with a fine four fine titanium chloride sodium reduction, the reduction product after removing, crushing, pickling and drying products made from titanium sponge.

  A method of a segment and a two segment sodium reduction, a method is complete reduction work in a reactor, the two segment method is complete reduction reaction in two reactors, in the first reactor reduced to low valence titanium compound, add sodium in a second reactor, complete to restore the whole process after sintering, the finished product of titanium sponge production.

Method for producing of four titanium chloride

The production method and the process of the selection in twentieth Century 80 time end stop, industrial production of  titanium sponge in two ways, namely by Kroll and Hunter method.

  Followed by the metal magnesium and sodium reduction four titanium chloride. Method for producing fine four titanium chloride two are the same.

The last century of titanium sponge plant expansion

In twentieth Century 60, titanium sponge factory of China built the largest, started for 1000t / A. And the initial size of titanium sponge plant in the west between 300 ~ 5000t / A, the former Soviet Union is 3000 ~ 10000t / A.

  Characteristics of titanium metal construction investment, the market more volatile and high production cost based, after 60 years, some foreign titanium sponge factory basically rely on technological innovation, and gradually expanded to the annual production capacity of more than 10000 tons of dachang.


  Chinese was completed in 1990 large-scale titanium sponge plant expansion, the expansion of the annual production capacity is 2000t. Design to determine the size of Xinhai titanium sponge factory, to adapt to the basic industrial technology level and market demand.

The Chinese and USA titanium sponge plant

Product scheme and design of the scale Chinese design of titanium sponge factory or workshop, the final product is only one kind of  titanium sponge.

  Titanium sponge plant in Japan and the former Soviet Union is also designed with ingot casting workshop, using the consumable electrode and non consumable electrode melting titanium ingots, titanium sponge production will account for 6% ~ 8% of titanium added to substandard titanium ingot, in order to improve the economic benefit.

  Titanium mill products in more than two, titanium sponge factory USA many and processing plant design as a whole, the main products for the multi specifications, many varieties of titanium material.

Chinese first titanium sponge plant

In twentieth Century 60, Chinese scientific research - float valve tower, used for titanium sponge factory, instead of packing tower equipment is huge and low efficiency; Chinese developed circular molten salt chlorinator, titanium slag effectively deal with Gao Gaimei content.

  In 70's, China initiated chlorination furnace titanium chloride slag by fluid production technology, has designed a variety of furnace type for the chlorination of  titanium slag. The 1964 design Chinese first titanium sponge factory - Zunyi titanium  plant, put into operation in 1970.
