Titanium, a spongy metal produced by thermal reduction of metals. Purity % (quality) is generally 99.1 ~ 99.7. The total impurity element % (mass) is 0.3 ~ 0.9, the impurity element oxygen % (mass) is 0.06 ~ 0.20, and the hardness (HB) is 100 ~ 157. It is the main raw material for producing industrial titanium alloy. Sponge titanium production is the basic link of titanium industry, it is the raw material of titanium materials, titanium powder and other titanium components. The ilmenite is turned into titanium tetrachloride, which is then placed in a sealed stainless steel tank filled with argon, which reacts with magnesium to produce titanium sponge. The porous titanium sponge cannot be used directly and must be melted into liquid in an electric furnace before it can be cast into ingots.

1. Boiling chlorination

Boiling chlorination is a method to produce titanium tetrachloride by using a fine particle titanium-rich material and a solid carbon (petroleum coke) reducing agent, which is fluidized under the action of high temperature and chlorine gas flow. This method can accelerate the process of mass and heat transfer between gas and solid phases and enhance production. The raw materials used for boiling chlorination at home and abroad are high titanium slag, natural rutile, artificial rutile and so on. Fushun titanium factory and zunyi titanium factory in our country's new boiling chlorination furnace diameter of 1.4 m and 2.4 m Φ Φ respectively, no sieve plate adopts the unique technology, chloride of zunyi titanium factory design nissan 70 t coarse titanium tetrachloride.
