Description

Technical Field

[0001] The utility model relates to a production device for titanium sponge, in particular to a heat exchange device for titanium sponge reduction production. Background Art

[0002] The industrial production of titanium sponge adopts the method of reducing titanium tetrachloride with magnesium. Most furnace types adopt the inverted "U" type combined production method, which is characterized by large single furnace output, high rate of high-quality products, and low energy consumption. The reduction of titanium tetrachloride with magnesium is an exothermic reaction. A large amount of heat is released during the reduction production. During the reduction period, the heat dissipation in the center of the reactor is not timely, and the temperature in the center of the reactor is high, resulting in sintering of the product in the center, an increase in the amount of hard blocks, a dense product structure, and too much MgCl2 in the center, which seriously affects the product quality and increases the production cost of titanium sponge. For this reason, some manufacturers use forced ventilation of the furnace shell to dissipate heat, which can only take away the heat on the surface of the reactor, but cannot solve the problem of heat dissipation in the center of the reactor. A reactor center heat dissipation device is now provided to improve the product structure and quality. Utility Model Content
