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.‍

Material characteristics of titanium alloys and welding

Material characteristics ( a ) titanium : density ( about 4.5g/cm3), high tensile strength (441 ~ 1470MPa), that is the great strength ratio ( strength / density ) large . In sea water and most acids, alkalis, salts medium all have excellent corrosion sunrui Titanium EB Slab resistance compared .

Weldability (b ) a titanium alloy , having a number of significant features, which are due to the physical and chemical characteristics of welding titanium is determined .

1 impurity contamination caused by gas embrittlement of welded joints

At room temperature , titanium and titanium alloys are relatively stable. However, in the welding process , the liquid metal droplet and the pool has a strong absorption effect of hydrogen, oxygen, nitrogen , and in the solid state , with these gases have a role. With increasing temperature , titanium and titanium alloys absorb hydrogen , oxygen, nitrogen capacity also will rise significantly , about 250 ℃ titanium began to absorb hydrogen , began to absorb oxygen from 400 ℃ , 600 ℃ began to absorb nitrogen from these after the gas is absorbed directly will cause embrittlement of welded joint is extremely important factor affecting the quality of welding .

( A ) Effect of hydrogen is

Impurities in the hydrogen gas to affect the mechanical properties of titanium most serious factor. The impact of changes in hydrogen content in the weld performance the most significant effect on the weld , mainly due to the increase of the hydrogen bomb with the seam with the amount deposited weld flake or needle TiH2 increased. TiH2 low intensity , the effect of the sheet-like or needle guard according to HiH2 notch impact sunrui Titanium Welded Tube properties significantly reduce aggregate ; weld hydrogen to reduce the amount of change effect of improving the strength and the ductility is not very significant .

( 2) The effect of oxygen

With the oxygen content of the weld is substantially increase the oxygen content in the argon gas increases linearly with the increase of the oxygen content of the weld , the weld hardness and tensile strength significantly increased , and the plasticity is significantly reduced. In order to ensure the performance of welded joints , the welding process should prevent the weld and HAZ fat oxidation.

( 3 ) the impact of nitrogen

At temperatures above 700 ℃ , plays the role of nitrogen and the titanium , titanium nitride is formed a hard brittle (TiN) is formed of titanium and nitrogen and the slip degree of lattice distortion caused by solid solution of the gap , the consequences caused by the same amount of oxygen than more seriously , so nitrogen to improve industrial pure titanium weld tensile strength , hardness, ductility properties of the weld reduced more significant than that of oxygen . When the nitrogen content in the weld than 0.13% , the weld due to the brittle and cracks .

( 4 ) the impact of carbon

Carbon is also common in titanium and titanium impurities, experiments showed that when the carbon content of 0.13 % or less, because deep in the α carbon titanium weld strength limit somewhat improved plasticity some decline, but not as strong role of oxygen and nitrogen . But when further increase the carbon content of the weld , the weld has appeared mesh TiC, their number increased with the carbon content and increase the weld plastic sharp decline in the welding prone to stress cracking . When the carbon content of 0.55% weld , the weld disappearance of almost all the plastic and the material becomes very brittle . sunrui titanium sponge Weld heat treatment can not eliminate this brittleness. Of technical conditions , the carbon content of the titanium alloy of the base material is not more than 0.1% , the carbon content of the weld does not exceed the base material carbon content.

2 titanium weld defects and Mechanism .

( 1 ) Color oxide

Around about 250 ℃ titanium begins to absorb hydrogen and oxygen to be absorbed from 400 ℃ , 600 ℃ starts from the absorption of nitrogen , and the air contains large amounts of nitrogen and oxygen species . Titanium during welding , argon gas protection layer is formed by welding guns can better protect the weld pool from the harmful effects of air , which has been solidified in the vicinity of the weld and no high-temperature state near protection, while the area around the weld titanium tube and in this state is still strong absorption of nitrogen and oxygen in the air capability . Gradually increased with the degree of oxidation , and changes in the laws of titanium weld seam plastic drop colors occur. Silver-white ( no oxidation ) , golden yellow (TiO, slightly oxidized ) , blue (Ti2O3, oxidation slightly serious ) , Sunrui titanium coils gray (TiO2, oxidation severe ) .
