remelting method of processing
The remelting method uses scrap titanium or sponge titanium as raw material and adds iron to remelt it. This method generally uses induction furnace remelting. It is also used to smelt in a consumable electric arc furnace or use molten steel to mix sponge titanium to produce high titanium ferro. Titanium scrap and scrap steel are used as raw materials and remelted in an induction furnace to produce ferrotitanium with about 70% Ti (Fe-Ti system has a eutectic point at about 68% Ti). To reduce the burning loss of titanium during the remelting process, the titanium scrap is packed in a steel cylinder and pressed tightly. Add a mixture of barium chloride and sodium chloride, cryolite, or a similar low melting point mixture as a flux to cover the titanium-iron melt. The remelting method can also produce various titanium composite alloys.
Developed countries such as Russia and Western Europe mainly use the remelting method to produce high titanium iron. In recent years, there have been new developments in the remelting process, and a process for preparing high titanium iron by smelting in a lined electro-slag furnace has emerged. This process was developed based on the principles and advantages of electro-slag remelting. It can eliminate the complex vacuum system of induction furnaces and consumable electric arc furnaces, reduce costs, and greatly simplify production operations. The quality of high-titanium iron produced by the remelting method is already very stable, especially in the control of oxygen content. However, because it uses scrap titanium as raw material, the source of raw materials is limited, the production cost is too high, and it is greatly affected by market prices.
