Furnace for abstracting high-purity magnesium metal by electromagnetic method

Abstract

The invention relates to a smelting furnace for extracting high-purity metallic magnesium, providing an electromagnetic method to extract the high-purity metallic magnesium furnace, which solves the technical problems of low pure magnesium yield, low purity and discontinuity of the production process of the prior art. The invention is a closed furnace body of which the outside is wound by an excitation coil; the excitation coil is connected electrically with a medium-high frequency power source; a furnace body are divided into a smelting area and a furnace slag area; the lower part of the smelting area is provided with a briquette; the bottom part of the furnace slag area is also provided with a magnetized body. The closed furnace for extracting the pure magnesium has the advantages of long service life, continuous production, high yield, non-pollution to environment, energy conversation, high purification rate and small floor area, and conveniently adjusts and controls the furnace temperature, thereby realizing the pure magnesium extraction by creatively using the electromagnetic method.

Description

technical field [0001] The invention relates to a nonferrous metal smelting furnace, in particular to a smelting furnace for extracting high-purity metal magnesium. Background technique [0002] At present, the Pidgeon method is mostly used to extract high-purity magnesium from crude magnesium. This method has the disadvantages of low yield of pure magnesium, low purity of finished magnesium from smelting, environmental pollution in the production process, high energy and raw material consumption, and no continuity in the production process. , The reduction tank covers a large area, high initial investment, high maintenance costs, short life of the "crucible", high labor intensity, long smelting time and unstable smelting temperature and other technical and social problems. There are also a small number of pure magnesium production enterprises using electrolysis. Although this method only increases a small part of the pollution of the electrolyte, greatly reduces the damage ...
