Submerged heating magnesium smelting furnace

Abstract

The invention discloses an immersed type heating magnesium smelting furnace. The immersed type heating magnesium smelting furnace comprises a furnace shell, a separated type furnace cover, a feeding device, a protective gas input device and a smelting crucible. The smelting crucible is embedded in the furnace shell. The separated type furnace cover covers the furnace shell. The feeding device and the protective gas input device are both fixed to the separated type furnace cover. The immersed type heating magnesium smelting furnace is characterized in that an immersed type heater and a discharge transmitting device are additionally arranged, the immersed type heater is detachably and fixedly connected with the separated type furnace cover, the upper end of the immersed type heater extends out of the separated type furnace cover, and the lower end of the immersed type heater is located in the smelting crucible and arranged below the separated type furnace cover; the discharge transmitting device penetrates through the furnace shell and the smelting crucible and is located at the bottom of the side face of the smelting crucible, one end of the discharge transmitting device is located in the smelting crucible, and the other end of the discharge transmitting device is located outside the furnace shell. By the adoption of the immersed type heating magnesium smelting furnace, the volume of molten magnesium or magnesium alloy can be increased, work efficiency is improved, and the heating efficiency is greatly improved; in addition, the arranged heating device can guarantee that air is isolated when feeding is conducted, and the quality of the molten magnesium or magnesium alloy is improved.

Description

technical field [0001] The invention relates to a magnesium smelting furnace, in particular to a submerged heating magnesium smelting furnace, which belongs to the technical field of magnesium alloy metallurgy. Background technique [0002] Magnesium and magnesium alloys are very important raw materials in today's society. Although my country is a big country with magnesium resources, its resources account for 60% of the world's total, but the price of my country's exported magnesium ingots and magnesium alloy ingots is very low. One of the main reasons is that my country's magnesium and magnesium alloy ingots are of poor quality and low added value. It cannot meet foreign technical requirements for high-quality magnesium ingots and magnesium alloy ingots. [0003] Magnesium smelting furnace is a special equipment for melting magnesium or magnesium alloys. At present, the magnesium industry in my country mostly smelts magnesium or magnesium alloys in open or semi-open magnes...
