The use of titanium in automobiles is mainly divided into two categories. The first category is to reduce the mass of internal combustion engine reciprocating parts (for internal combustion engine parts that reciprocate, even reducing the mass of a few grams is important); the second category It is used to reduce the total mass of the car. According to the design and material characteristics, titanium is mainly distributed in engine components and chassis parts in new-generation cars. In the engine system, titanium can be used to make parts such as valves, valve springs, valve spring holders and connecting rods; in the chassis parts are mainly springs, exhaust systems, half shafts and fasteners.
According to the information, in addition to the above mentioned key points, there are rocker arms, suspension springs, piston pins, turbocharger rotors, fasteners, lug nuts, car stop brackets, door projection beams, brakes Caliper piston, pin, clutch disc, pressure plate, shift button, etc.
Ways to reduce the cost of titanium alloys
Although titanium and titanium alloys entered the field of automobile manufacturing as early as the 1950s, the development was relatively slow. The main reason was the price factors. A lot of work. To meet the needs of the automotive industry.
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 commonly used in industry produces sponge titanium.
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. The practice has shown that every 1% of residual titanium used can reduce the production cost of titanium ingots by 0.8%. If an electron beam cooling bed furnace or a plasma beam cooling bed furnace is used for smelting, not only can the metallurgical quality of titanium ingots be improved, but also recycled charge can be used in large quantities, effectively reducing the cost of ingot casting.
