The system includes a raw material predrying kiln, a preheating kiln, a reduction rotary kiln, a cooling rotary kiln, a ball mill, a magnetic separator, a reduced iron powder drying kiln, a blank prefabricator, a blank drying kiln, a sintering furnace, a fused salt electrolysis tank, a titanium cleaning device, a filtering device, a vacuum dryer, a waste heat boiler, and a steam turbine generator. In the present disclosure, a high-temperature flue gas produced by the reduction rotary kiln is directly used to preheat a raw material. The CO-containing high-temperature flue gas discharged by the reduction rotary kiln and the CO discharged at the fused salt electrolysis stage are recovered and used for power generation and steam production of the waste heat boiler. Due to a low moisture content of the flue gas, a low-temperature flue gas obtained after the waste heat recovery is used for drying.

The present invention belongs to the field of titanium metallurgy, and particularly relates to a method for preparing a titanium-aluminum alloy. The technical problem to be solved by the present invention is to provide a method for preparing a titanium-aluminum alloy, including the following steps: a. adding TiCl.sub.4 and AlCl.sub.3 to a molten electrolyte in a protective atmosphere, wherein the molten electrolyte is a mixture of at least one of alkali metal chloride or alkaline earth metal chloride and alkali metal fluoride; b. electrolyzing the mixture obtained in step a; and c. obtaining a titanium-aluminum alloy through vacuum distillation of a cathode product after electrolysis.

A device and a method for preparing pure titanium by electrolysis-chlorination-electrolysis, wherein the device includes a first electrolytic cell, a second electrolytic cell, a chlorination reactor and guide tubes. The Cl.sub.2 generated at the anode of the first electrolytic cell is introduced into a chlorination reactor containing the TiC.sub.xO.sub.y or TiC.sub.xO.sub.yN.sub.z raw materials via a guide tube, and a chlorination is carried out to generate TiCl.sub.4 gas at a temperature of 200° C.-600° C.
