Description

Technical Field

[0001] The utility model belongs to the technical field of white corundum production, and in particular relates to an electric arc furnace for smelting white corundum. Background Art

[0002] The smelting of white corundum is completed by a dumping furnace. First, bauxite or alumina powder and other reducing agents and other formula materials are added to the dumping furnace body, and then an electric current is sent through three electrodes to melt the charge in the furnace body and react with the reducing agent. After the reaction is completed, the high-temperature melt in the furnace is poured into the receiving bag to obtain the white corundum product. When the smelting of white corundum is completed, due to its high internal temperature, the white corundum inside needs to be dumped into the receiving bag device, and then the receiving bag device is moved to the cooling device to take the high-temperature white corundum inside the receiving bag device for cooling treatment.
