Magnesium smelting technique by microwave heating

Abstract

The invention discloses a magnesium smelting technique by microwave heating and relates to the field of magnesium smelting techniques. The upper end of the round wall of a furnace body is connected with an expander by bricklaying through a refractory material, and the lower end of the round wall of the furnace body is fixed with a tray; the expander is movably connected with a support in a sliding manner; the lower end of a microporous ceramic tube is fixed with the tray while the upper end of the microporous ceramic tube is fixed with the support; the furnace body is fixed with a microwave generator and a shell; the shell is fixed with an upper flange and a lower flange; a gaseous magnesium collecting chamber is formed by the wall of the furnace body above the support, an upper convergent section of the shell and the inner side of the upper flange; a gaseous magnesium outlet tube is penetrated from the gaseous magnesium collecting chamber and then is fixed with the furnace body and the shell; a slag chamber is formed by the wall of the furnace body below the tray, a lower convergent section of the shell and the inner side of the lower flange; a magnesium ball is put in the microporous ceramic tube; slag is put in the slag chamber; the power of the microwave generator is 1-500KW, the frequency of the microwave generator is 300-3000MHz, the temperature of the microwave generator is 1200-1350 DEG C, and the smelting time is 15-60 minutes; the magnesium ball is acquired by roasting dolomite to acquire magnesium oxide and calcium oxide and then mixing silicon iron and fluorite with magnesium oxide and calcium oxide. The magnesium smelting technique by microwave heating is used for smelting magnesium, which is a microwave new energy heating technology.

Description

technical field [0001] The microwave heating magnesium smelting technology of the present invention relates to the technical field of metallurgy; in particular, it relates to the technical field of magnesium smelting; in particular, it relates to the technical field of microwave heating magnesium smelting furnace and technical control. Background technique [0002] Among practical metal materials, magnesium and its alloys have low density and are known as ultra-light materials in the 21st century. Adding ceramic reinforcements to magnesium can significantly improve the elastic modulus, strength, wear resistance and high temperature resistance. Compared with other metals, magnesium has lower density, higher specific stiffness and good damping properties. It is used in aviation and aerospace. There is a strong interest in industrial applications, and it is the most desirable material in today's national defense and high-tech fields. Its wide application prospects are showing a...
