The world titanium industry is competing to develop new technologies
There are currently six sponge titanium production plants abroad. Except for the production capacity of Timet of the United States of 8000t / a, the other annual production capacity is more than 10,000 tons. Among them, the chlorine consumption of sponge titanium machining in Japan is 0.9t / t sponge titanium, and the steam consumption is 2500kWh / t sponge titanium, which are lower than the similar indicators of domestic enterprises.
The fundamental application of titanium is to reduce costs. In order to achieve this, on the basis of the preparation of titanium metal by Cambridge TiO2 electrolysis in the United Kingdom, Timet of the United States invested heavily in the industrial test of this method, while Japan is engaged in an industrial test of the improved Cambridge method, possibly in 5 years. After the initial industrial production. This new method will reduce the cost of titanium metal by one-third to one-half, possibly triggering a revolution in the titanium industry.
U.S., European and Russian titanium processing materials are mainly used in large civil airliners, military aircraft, aerospace rockets, missiles, ships, armored artillery, electric power, chemicals, automobiles and other fields. Its typical products are aircraft structural parts, titanium brake parts, compressor blades and bases, hydrofoils, propellers and shafts, brackets, floats, torpedo launchers, high-pressure gas cylinders and all-titanium condensers. To this end, they developed a large electron beam or plasma cold bed furnace melting furnace, a large profile production line, and a large machining titanium production line (Russia ’s Upper Salda Company has the world ’s largest 75,000-ton hydraulic press, capable of producing 3.2-ton titanium forgings), Large casting production line with a single piece weight above 770Kg, etc. In terms of new titanium alloys, they have developed high-temperature titanium alloys at 600 ° C (IMI834 alloy in the United Kingdom and Ti-1100 titanium alloy in the United States) and high-strength titanium alloys (such as Ti-1023, Ti-15-3, β21S in the United States, etc.) , Flame retardant titanium alloy Al-loyC (Ti-35V-15Cr), TiAl alloy, and low-cost titanium alloy (such as the United States Ti-4.5Fe-6.8Mo-1.5Al) and so on.
The civilian technology of the Japanese titanium industry is at the forefront of the world. If there is a sponge titanium enterprise with the best economic index, there is a large coil heavy titanium belt production line of Yigang. Its civilian titanium products cover chemical, petrochemical, construction, metallurgy, medical (human implants, wheelchairs, etc.), transportation (cars, motorcycles), sports (golf equipment, tennis rackets, fishing gear, fishing boats, etc.), daily use Various departments of electronic products (cameras, watches, copiers, typewriters, mobile phones, laptops, etc.), cookware (knives, *, pots, spades, etc.).
Judging from the development status of titanium technology in the world, its development trend can be summarized as follows:
