Production process of titanium aluminum profiles

Reducing the price of titanium alloy materials such as titanium rods, titanium plates, and titanium wires must be carried out from two aspects: the development of new low-cost alloys and the improvement of production processes:

1. Reduce raw material costs

Titanium has a high melting point and very active chemical properties. It has a strong chemical affinity with elements such as O, H, N and C, which makes it difficult to extract pure titanium. The Kroll magnesium reduction method is widely used in industry to produce sponge titanium. The Kroll magnesium reduction method produces sponge titanium with a complex process, high energy consumption, long cycle time, and cannot be continuously produced. At the same time, a large amount of metallic magnesium is required as a reducing agent, and the production cost is relatively high. At present, the process of direct electrochemical reduction of TiO2 in molten CaCl2 developed by the University of Cambridge in the United Kingdom has made a breakthrough. This method has a short production cycle for producing sponge titanium, and the production cost has been reduced by 40%.

Titanium alloys mostly use high-priced V as alloying elements to increase their strength, and these alloying elements are mostly added with Al-X as a master alloy. Substituting cheap Fe, Cr and other alloying elements for V is an effective way to reduce the cost of titanium alloys.

With the advancement of titanium smelting technology, it is an effective method to reduce the cost of raw materials to add the leftovers and scraps generated during the production and processing of titanium as furnace charge after a series of treatments to achieve recycling.

2. Reduce processing costs

Casting is a classic net (near) forming process. The parts produced do not need to be machined or machined very little, which saves a lot of metal. Casting can often produce parts with complex shapes, and when these parts are manufactured by other traditional methods, the process is complicated and the production cost is relatively high, especially for titanium, which has relatively high material prices. At present, titanium castings are widely used in the aviation industry. In the automobile manufacturing industry, parts produced by casting methods include valves and turbochargers. Powder metallurgy, as an advanced technology method of modern metallurgy and material processing, has played an important role in the titanium industry. The use of titanium powder metallurgy near-forming technology can directly produce finished products or parts close to the finished size, which reduces the consumption of raw materials, shortens the processing cycle, and saves 20% to 50% of the cost compared with conventional processes. At present, the research of titanium powder metallurgy is in a stage of rapid development, which mainly includes several aspects. One is the preparation technology of high-quality and low-cost titanium powder and its industrialization; the other is the preparation technology of titanium powder metallurgy, which is also popularized and applied in the automobile industry.
