Problems solved by technology

[0003] The production of ferro-titanium mainly adopts the production process of reduction method, but due to the high oxygen content in the preparation process of the thermite method, the yield of metal produced is low, and the content of impurity elements is not up to the standard; the main raw material of the remelting method is titanium sponge, which is subject to The source is limited, the price is expensive, the production process needs to be vacuumed, and the cost is very high

Description

technical field [0001] The invention relates to the technical field of ferro-titanium alloy smelting, in particular to a production process of ferro-titanium alloy powder. Background technique [0002] Pure titanium is a silver-gray metal with metallic luster. It has good ductility when heated, and its powder is dark gray. As a strategic resource, titanium is mainly used in high-strength alloys for aircraft and missile structural components, high-temperature high-strength alloys such as gas turbine blades, age-hardening superalloys, high-temperature casting alloys, etc. Titanium forms two compounds with iron: TiFe 2 and TiFe, of which only TiFe is stable, and TiFe 2 Exists only in solid alloys. Ferro-titanium is an alloy of titanium and iron. The melting point of ferro-titanium is between 1400~1500℃ due to its different chemical composition, and its density is 5.7~6.4g / cm 3 . Ferro-titanium is widely used in metallurgical production. It can be used as a deoxidizer, deni...
