Industry in the production of alloy metabolism process, the main raw materials are rutile, waste titanium metal, titanium iron gold ore, etc., which we said in addition to the waste titanium metal material, are required to use a reducing agent for the reduction reaction, in order to get the recovery of titanium chips, pure titanium chips is a very difficult to reduce the oxide, only in the high temperature of the conditions of the use of carbon as a reductant in order to achieve the purpose, and the production of products is often titanium carbide rather than pure titanium.
If you want to get high carbon ferro-titanium just use silicon to reduce, titanium oxide is not able to achieve this purpose, often need to add calcium oxide as a catalyst in it, which in turn leads to the generation of restitution reaction. We recover titanium chips are often the use of three methods can be produced, respectively, for the electric silicon heat method, electric carbon heat method and remelting method, the use of coke as a reductant in small electric furnaces, and add a large number of lime as a solvent, will be able to produce an alloy of titanium chips, this alloy of titanium chips with a low carbon content, in addition to the furnace can be added to the silica if you can increase the proportion of silica. Can be smelted out of the high silicon content of low carbon high silicon alloy titanium chips.
The use of electrosilicon heat method to produce the alloy titanium chips, often the use of silicon reduction to produce some composite alloys, if you add other oxides or other ferroalloys, it can be made into a variety of elements of titanium alloys. In addition, remelting is a process that utilizes steel and titanium scrap as the main raw materials, which are remelted in an induction furnace to produce alloys containing up to 70% silicon. In order to minimize the loss of silicon during the reaction process, the scrap is often packed in steel cylinders and covered with a mixture of barium chloride and sodium chloride, as well as low melting point mixtures as solvents to minimize the loss of silicon. The production process of recycling titanium scrap is introduced here today, hoping to help you better understand this alloy.
