Pollution-free clean taking-out method after production of titanium sponge

Abstract

The invention discloses a pollution-free clean taking-out method after production of titanium sponge, and relates to the technical field of production of titanium sponge. The pollution-free clean taking-out method comprises a reaction kettle, a reaction kettle flange and a sealing head lifting lug, wherein a reaction kettle large cover is mounted above the reaction kettle; a charging system is arranged at the outer side above the reaction kettle large cover; a finished product produced by the inner wall above the reaction kettle is wall-climbing titanium; and a finished product produced by the lower part inside the reaction kettle is a titanium lump. The pollution-free clean taking-out method has the beneficial effects that: the pollution-free clean taking-out method after production of titanium sponge adopts a reverse dismounting, reverse cleaning and forward taking method, is relatively scientific and practical, has personnel operability, reduces uncertainty of influence factors during taking of the titanium sponge lump, can prevent titanium sponge low-price substances from being inflammable and easily absorbing moisture, improves safety, effectively prevents impurities such as low-price substances and distilled magnesium from polluting the titanium lump to cause secondary pollution, and avoids a risk that foreign matters such as distilled magnesium enter titanium sponge, so that the yield and appearance quality of titanium sponge are effectively improved.

Description

technical field [0001] The invention relates to the technical field of titanium sponge production, in particular to a pollution-free and clean removal method for titanium sponge after production. Background technique [0002] In the current production method of sponge titanium, sponge titanium is chemically reacted in a closed container, and liquid magnesium is used to reduce liquid titanium tetrachloride to produce sponge titanium. This process is a disproportionation reaction. During the reaction process, the existence of the cold zone of the reactor; the reaction of steam and steam between the raw materials; especially in the later stage when the amount of magnesium is insufficient and the replacement reaction is not complete, low-priced substances will be generated, commonly known as "black powder". Although titanium sponge has a secondary reaction during the formation process, part of the black powder and low-priced titanium particles that have not undergone secondary r...

AI Technical Summary

Problems solved by technology

[0004] The object of the present invention is to provide a method for cleaning and removing sponge titanium after production, so as to solve the problem that the existing cleaning method for titanium sponge after production proposed in the above-mentioned background technology is in the cleaning process or the cleaning is not thorough when it is being dismantled. Under the circumstances, part of the black powder and low-priced titanium particles that have not undergone secondary reactions are easy to scatter on the wall-climbing titanium and titanium lumps, and secondary pollution of titanium lumps may occur.
