Liquid vacuum stirring metallurgy device and method

Abstract

The invention provides a liquid relative-vacuum stirring metallurgy device and method. The device comprises a vacuum feeding system, a vacuum reduction system, a slagging device and a collecting and purifying system, wherein furnace charge is transported to the vacuum reduction system through a vacuum feeding sealed tank and a telescopic charging pipe; the vacuum reduction system is used for conducting vacuum reduction treatment on the furnace charge; a stirring head is arranged below a stirring mechanism rotator, the stirring head is inserted into a liquid reduction agent in a vacuum tank ina stirring mechanism vacuum chamber, the telescopic charging pipe is used for adding reduced powder to the surface of the liquid reduction agent, the reduced powder and the liquid reduction agent arestirred by the stirring head, and the reduced powder and the liquid reduction agent are subjected to a reduction reaction to generate metallic vapor; the slagging system is used for treating furnace slag generated after treatment of the vacuum treatment system; and the collecting and purifying system is used for collecting and purifying the target metallic vapor and non-target metal which are generated by the vacuum reduction system. By means of the liquid relative-vacuum stirring metallurgy device and method, the problems of serious splashing and the like of an existing liquid silicothermic injection method can be solved.

Description

technical field [0001] The invention relates to the technical field of metal smelting, and relates to a device and method for producing volatile metals or some non-volatile metal alloys by mixing reductant powder into a liquid reducing agent, which can be used for the reduction production of metal magnesium, lithium, zinc and lead . Background technique [0002] Metal magnesium, lithium, lead, and zinc have one thing in common: they are gaseous at the temperature of the liquid reducing agent. In view of this common point, the principles of smelting magnesium, lithium, lead, and zinc metals are the same, so the same smelting equipment and smelting methods can be used Smelting magnesium, lithium, lead and zinc metals. Among them, the following takes metal magnesium as an example to introduce the current status of such metal smelting. [0003] At present, the production methods of metal magnesium are mainly divided into two categories, one is the electrolysis of magnesium chl...
