Our company is adjacent to the high-quality titanium sponge production base, and raw material purchases are made of grade 0 and grade 1 titanium sponge, which fundamentally guarantees the quality of the product and lays the foundation for the subsequent processing of the product and the quality of the final product.
At present, the industrial method for the production of titanium metal is the Kraul method, and the product is titanium sponge. The traditional process of making titanium is to melt and cast sponge titanium into ingots, and then process them into titanium. According to this, the main steps of the technological process from mining to making titanium are: titanium ore -> mining -> beneficiation -> too concentrate -> enrichment -> titanium-rich material -> chlorination -> crude TiCl4-> Refining -> Pure TiCl4-> Magnesium reduction -> Sponge titanium -> Casting -> Titanium ingots -> Processing -> Titanium material or titanium parts. Chemical preparation of crude TiCI4. In addition, the casting operation should be a metallurgical process, but sometimes it is also classified as a processing process.
The processing in the above process refers to plastic processing and casting. Plastic processing methods include forging, extrusion, rolling, stretching and so on. It can process titanium ingots into various sizes of cakes, rings, plates, pipes, bars, profiles and other products, and can also be cast into various shapes of parts and components. Plastic processing of titanium and titanium alloys has the characteristics of large deformation resistance; normal temperature plasticity difference, high yield limit and strength limit ratio, large rebound, sensitive to notches, easy to bond with molds during deformation, and easy to absorb harmful gases when heated, etc. Plastic processing is more difficult than steel and copper.
Therefore, the processing technology of titanium and titanium alloys must consider these characteristics of them.
Titanium adopts plastic processing, the processing size is not limited, and it can be mass-produced, but the yield rate is low, and a large amount of scraps and residues are generated during the processing. In view of the above shortcomings of titanium plastic processing, powder metallurgy technology has been developed in recent years. The powder metallurgy process of titanium is the same as ordinary powder metallurgy, but the sintering must be carried out under vacuum. It is suitable for the production of large-volume, small-sized parts, and is especially suitable for the production of complex parts. This method requires almost no processing and has a high yield rate. It can not only make full use of titanium waste as raw materials, but also reduce production costs, but it cannot produce large-size titanium parts. The powder metallurgy process of titanium is: titanium powder (or titanium alloy powder) -> sieving -> mixing -> press forming -> sintering -> auxiliary processing -> titanium products.
