Embodiment Construction

[0016] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0017] As shown in Figure 1, the multi-heat source-electrothermal method smelting magnesium device of the present invention adopts a circular vertical vacuum furnace body, which is mainly composed of a steel furnace shell 3, a refractory layer 5 and a thermal insulation layer 4 inner lining arranged in the furnace shell 3 , such as the combination of magnesia refractory material and insulation cotton. The furnace body is provided with a reaction bin 20 and a hot slag bin 6 which communicate with each other. The upper part of the furnace body is provided with a heat insulation layer 16 and a furnace cover 15. The upper part of the furnace body inlet is provided with a feed bin 11 and a storage bin 13. A primary feed vacuum valve 12 is installed between the bin 11 and the storage bin 13, a secondary feed vacuum valve 14 is installed between the storage bin 13 and the f...

Abstract

The present invention relates to multiple heat source-electrothermal magnesium smelting apparatus and process. The magnesium smelting apparatus includes one vertical vacuum furnace with reactor, hot slag bin, furnace body heat isolator, feeding bin, one material, heater and electrodes inside the reactor; one magnesium crystallizer on the furnace; one cold slag bin blow the hot slag bin; and several vacuum valves. The present invention has high heating speed, high production efficiency, no pollution, high production adaptability, low labor strength, low production cost and high magnesium yield.

Description

technical field [0001] The invention relates to a metal reduction device and process, in particular to a multi-heat source-electrothermal method for smelting magnesium and a process. Background technique [0002] Metal magnesium is widely used, and the demand for magnesium in the world is increasing at a rate of more than 10% every year. my country's magnesium output accounts for more than 60% of the world's total output, about 500,000 tons, and it is an important export material with international competitiveness. More than 95% of my country's magnesium production is produced by the backward Pidgeon method, which has high cost, low efficiency, high labor intensity and serious pollution. [0003] Existing technologies such as "Pidgeon method", "tubular thermal magnesium smelting production process and its equipment" and "internal thermal magnesium smelting production process and equipment", "reduction tank vertical metal magnesium reduction kiln", "a kind of storage "Therm...
