Abstract

The invention relates to a semi-continuous production metal vacuum smelting reduction device which comprises a reduction tank that is communicated with a liquid state crystallizer arranged outside the reduction tank by a diversion device; the liquid state crystallizer comprises a crystallizer shell which is provided with a containing space, and is provided with a crystallizer heating control device used for controlling the temperature of the containing space and a crystallizer vacuum extractor used for controlling the vacuum degree of the containing space; and the crystallizer shell is also provided with an intermediate pipeline used for communicating a liquid state intermediate packet. The device can be used for realizing semi-continuous production of metal vacuum smelting, thus improving the production efficiency and reducing the production cost.

Description

technical field [0001] The invention relates to a metal vacuum smelting reduction tank, in particular to a vacuum smelting reduction tank for smelting metal magnesium or calcium. Background technique [0002] Some alkali metals and alkaline earth metals with high vapor pressure, such as chromium, chromium, magnesium, calcium, etc., can be prepared by metallothermic reduction of silicon, aluminum or their alloys under vacuum conditions. Among the metallothermal reduction preparation methods of magnesium, the silicothermal or aluminothermic metalthermal reduction principles are most widely used, but the reducing agent is mostly used in the form of ferrosilicon alloy, and the raw material to be reduced is mostly calcined dolomite. A wrought product of a mixture of magnesite and limestone can also be used. The use of ferrosilicon reducing agent, known as silicothermal magnesium smelting, is the most widely used. [0003] According to the different heating methods, the current ...
