Gr23 Titanium Processing

The industrial method for the production of titanium metal Gr23 is the Kroll method, the product of which is titanium sponge. The traditional process for producing titanium is to melt and cast titanium sponge into ingots, which are then processed into titanium rods. Accordingly, the main steps in the process from mining to titanium are:
Titanium ore -> Mining -> Beneficiation -> Terra-concentrate -> Enrichment -> Titanium-rich material -> Chlorination -> Crude TiCl4 -> Refining -> Pure TiCl4 -> Magnesium reduction -> Titanium sponge -> Melting and casting -> Ingot -> Processing -> Titanium or titanium parts In the above steps, if rutile is obtained from the mining, then it does not need to go through the enrichment process, and it can be chlorinated directly to obtain crude TiCI4. In addition, the melting and casting operation is a metallurgical process. metallurgical process, but it is sometimes categorized as a processing process.

Processing in the above process refers to plastic processing and casting. Plastic processing methods also include forging, extrusion, rolling, stretching and so on. It can be processed into various sizes of titanium ingots.
Size of the cake material, ring material, plate, tube, bar, profile and other products, can also be made into various shapes of casting parts, components.
Titanium and titanium alloy plastic processing with deformation resistance; room temperature plasticity is poor, yield limit and strength limit ratio is high, rebound, notch sensitive, deformation process is easy to bond with the mold, heating and easy to absorb harmful gases and other characteristics of plastic processing than steel, copper and other difficulties. Therefore, titanium and titanium alloy processing technology must consider these characteristics.
Titanium plastic processing, plus soil size is not restricted, and can be mass production, but the low rate of material, the process produces a large number of scrap residue. For titanium plastic processing of the above shortcomings, in recent years the development of titanium powder metallurgy process. Titanium powder metallurgy process is the same as ordinary powder metallurgy, only sintering must be carried out under vacuum. It is suitable for the production of large quantities, small size parts, especially for the production of complex parts. This method is almost no need to go through the processing treatment, high rate of material, not only can make full use of titanium waste as raw materials, but also can reduce the production cost, but can not produce large-sized titanium parts. Titanium powder metallurgy process: titanium powder (or titanium alloy powder) -> sieving -> mixing -> press molding -> sintering -> auxiliary processing -> titanium products.
