Method for producing small-particle sponge titanium and special device thereof

Abstract

The invention discloses a method for producing small-particle titanium sponge and a special device thereof, and relates to the field of titanium sponge production, the special device comprises a reduction furnace, a mixing furnace, a rectifying tower, a refining furnace and a reaction furnace, and the top of the mixing furnace is provided with a gas inlet pipeline. By arranging the liquid pushing assembly, after chlorine and nitrogen continuously enter the mixing furnace through a gas inlet pipeline, blades are impacted by gas flow to rotate, a movable shaft is driven to rotate, then a driving belt wheel is driven to rotate, then a transmission belt is driven to rotate, a driven belt wheel is made to rotate, and a rotating disc is made to rotate; after the rotating disc rotates, the connecting rod is pulled, so that the connecting rod rotates and pulls the sliding block to move, and after the sliding block moves, the liquid pushing piece is driven to move, so that the liquid pushing piece pushes away titanium slag and petroleum coke suspended in sodium chloride molten salt, and the titanium slag and the petroleum coke are pushed away and can be in full contact with chlorine gas and react with the chlorine gas, and when the rotating disc continuously rotates, the liquid pushing piece can move back and forth. And the preparation efficiency of the materials in the mixing furnace is further improved.

Description

technical field [0001] The invention relates to the field of sponge titanium production, in particular to a method for producing small particle sponge titanium and a special device thereof. Background technique [0002] Sponge titanium is spongy metal titanium produced by metallothermic reduction method, the purity (mass) is generally 99.1%-99.7%; the total amount of impurity elements (mass) is 0.3%-0.9%, and the impurity element oxygen (mass) is 0.06% -0.20%, hardness (HB) is 100-157, divided into five grades from MHTiO to MHTi4 according to the purity; sponge titanium is the main raw material for producing industrial titanium alloys; sponge titanium production is the basic link of the titanium industry, it is Titanium material, titanium powder and other raw materials for titanium components, turn ilmenite into titanium tetrachloride, put it in a sealed stainless steel tank, fill it with argon gas, and make them react with metal magnesium to get "sponge titanium" ; This ki...
