At present, the industrial production of titanium sponge at home and abroad adopts a method for reducing titanium tetrachloride by magnesium. The method comprises the steps of adding liquid magnesium into a reactor, continuously adding titanium tetrachloride to react with the liquid magnesium to obtain granular titanium, slowly forming titanium sponge lump, after reduction charging production is finished, carrying out distillation production to remove a small amount of magnesium and magnesium chloride in the titanium lump, and adopting a distillation furnace type mode to comprise a series furnace and a parallel furnace (an inverted U-shaped combination method). In the reduction distillation production process, most furnace types are produced by adopting an inverted U-shaped combined method, and the method has the advantages of large yield, high qualification rate, low energy consumption, low labor cost and the like compared with a small single furnace. In order to improve the production quality of the titanium sponge and reduce the production cost, the large-scale equipment is taken as a technical development direction in all countries.
