Process for charging titanium tetrachloride for use in preparation of titanium sponge by magnesium method

Abstract

The invention discloses a titanium tetrachloride feeding method to manufacture titanium sponge through magnesium method, which is characterized by the following: setting an external heating device before the titanium tetrachloride is transmitted into reactor through feeding pipe, which gasifies the titanium tetrachloride; the gaseous titanium tetrachloride contacts metal liquid magnesium evenly to do reducing reaction; the external heating device contains external cylinder, closing plate, cylinder, heating element and flame-proof insulating material; two ends of external cylinder possesses closing plate, which contains an inner cylinder in the external cylinder; the heating element is set near to inner cylinder; the flame-proof insulating material is set among heating element, external cylinder and inner cylinder.

Description

technical field [0001] The invention relates to non-ferrous metal smelting, in particular to a method for producing sponge titanium by a magnesium method. Background technique [0002] The process of producing titanium sponge by the magnesium method is to add titanium tetrachloride to the reactor, reduce it with metal magnesium, and obtain titanium sponge after distillation and purification. In the prior art of the reduction process, the liquid titanium tetrachloride at normal temperature is directly added into the reactor through the feeding pipeline to contact with the liquid metal magnesium in the reactor to carry out the reduction reaction. The development direction of the titanium industry lies in the large-scale output of a single furnace. In the case of a large reactor capacity, the temperature in the reactor can be as high as 800-920 °C. Titanium tetrachloride is fed into the middle of the reactor, and most of the titanium tetrachloride It will be gasified and react...

Problems solved by technology

[0008] The purpose of the present invention is just to provide a kind of titanium tetrachloride gasification feeding method of producing sponge titanium by magnesium method, after titanium tetrachloride is fully gasified earlier, make titanium tetrachloride enter in the reactor with gaseous state and then mix with Magnesium carries out the reduction reaction, so that the reduction reaction is carried out more uniformly in the reactor, effectively solving the heat accumulation problem of magnesium reduction titanium tetrachloride, improving the density of sponge titanium and improving the quality of sponge titanium
