Problems solved by technology

[0005] 1) Low effective utilization of energy and raw materials
[0006] The reduction period is long, and the energy utilization rate is extremely low; the service life of the reduction tank is short, resulting in high cost; the existing silithermal magnesium metal smelting process consumes 4.5 tons of standard coal per ton of magnesium, and there is still a large potential for energy saving
In terms of raw material utilization, the utilization rate is low, which indirectly increases energy consumption
[0007] 2) High labor intensity and low labor productivity
[0009] 3) Poor working environment
Environmental pressure is high
[0011] 4) Unable to mechanize production and automation
[0013] 5) Lack of high-quality magnesium and magnesium alloy products
The internal heating type magnesium smelting furnace

Abstract

The invention discloses a vacuum smelting furnace for reducing magnesium metal. The vacuum smelting furnace for reducing the magnesium metal comprises a vacuum feeding device and a furnace body, and the vacuum smelting furnace further comprises an induction heater, a microwave heater, a vacuum discharging device, a condensation tank and a crystallizer, and a vacuum system; the induction heater isarranged at the upper part in the furnace body; the microwave heater is arranged at the lower part outside the furnace body; the vacuum feeding device is used for adding reaction materials to the reactor in the furnace body, magnesium vapor generated by the reaction enters the condensation tank located at the top of the furnace body to crystallize in the crystallizer; the vacuum discharging device is located at the bottom of the furnace body to discharge the reacted and treated materials; the vacuum system is used for ensuring that the whole vacuum smelting furnace works under vacuum conditions, and the connection among the components is carried out according to the requirements of the vacuum conditions. connection. The vacuum smelting furnace provided by the invention completely adopts the mechanized and automatic structure, saves energy, reduces labor intensity of workers under high temperature conditions and improves working efficiency.

Description

technical field [0001] The invention belongs to the technical field of light metals, in particular to a vacuum smelting furnace for reducing metal magnesium. Background technique [0002] It has been 210 years since metal magnesium was discovered. Although its industrial production history is only 132 years, it has become a metal material widely used in aerospace, automobile, electronics, optical equipment, precision machinery, electrical appliances, transportation and other industries. The smelting process of metal magnesium mainly includes electrolysis method and thermal reduction method. In the 20th century, 80% of the world's primary magnesium production was produced by electrolysis and 20% by thermal reduction. After the 1990s, the output of primary magnesium by the thermal reduction method increased rapidly. In addition, the production cost of the electrolysis method was relatively high, and the electrolysis methods at home and abroad were closed one after another. A...
