Problems solved by technology

①The heat conduction radius is large, the heat loss is large, the environment is seriously polluted, and the reduction time is long for 12-14 hours; ②All manual operations, the labor intensity of the on-site workers is high, and the efficiency is low; ③The production cost is high, mainly due to high energy consumption and high cost of the reduction tank , low yield, unsatisfactory economic benefits; ④ can not form large-scale continuous production, does not meet the requirements of modern large-scale industrial development
Aiming at the current backward magnesium smelting technology and production defects, the point of view of molten silicothermal reduction magnesium smelting was put forward. However, due to the restriction of the circulation mechanism of single and double dipping tubes, the volume of the silicon thermal bath is extremely high, and the heating is difficult. The continuous production is not possible, the site requirements are harsh, the investment and production scale are extremely large, and in the environment exposed to the atmosphere, the yield of magnesium metal is low

Abstract

The invention discloses a molten carbon heating type induction furnace based vacuum magnesium production system. The system is characterized by comprising a pulverizing system, a preheating decomposing system, a roasting system, a secondary heating system, a vacuum reaction system and a condensing collecting system which are sequentially connected. The magnesium production method of the system comprises three stages, namely, the preparation stage, the induction furnace based vacuum magnesium production stage, and the starting and stopping stage after finishing. According to the system and the method, magnesium-contained powder which is pulverized, decomposed and heated is utilized; a melting tank in which iron is molten into liquid is subjected to vacuum treatment and then charged with argon; high-temperature carbon powder and the magnesium-contained powder are sprayed in the melting tank to reduce so as to produce magnesium steam; the magnesium steam is converted into molten magnesium after being collected and condensed, wherein the molten magnesium is coarse magnesium which is refined to obtain a magnesium ingot. The system and the method are reasonable and compact in production process, complete in equipment coordination and process, fast to react, short in reacting time, and high in production efficiency, and can reduce more than 1 / 3 of the production cost.

Description

technical field [0001] The invention relates to a metal smelting system and a method thereof, in particular to a molten carbon thermal induction furnace vacuum magnesium smelting system and a magnesium smelting method with high yield, low cost and less environmental pollution. Background technique [0002] Magnesium is an extremely abundant metal element in the earth, accounting for about 2.1% to 2.7% of the total mass of the earth. my country has the largest reserves of magnesium resources in the world. At present, tens of billions of tons have been proven. Magnesium and magnesium alloys have small specific gravity, high strength, good shock absorption, impact resistance, good machinability, good thermal conductivity, can be recycled and reused, have less environmental pollution, have excellent environmental advantages and performance advantages, and have a wide range of applications. It is a rare metal that can be recycled. Vigorously developing the magnesium industry ha...
