The functions of the carbonization charge layer are: to protect the charge from oxidation at high temperature, so as to ensure that the metal elements in the slag will not volatilize; to maintain the carbothermal reduction reaction in the molten state, to ensure that the charge is smelted at the optimum temperature and time. The main function of the electric arc furnace is to introduce an electric arc into the charge to melt the molten carbon steel material into a metal alloy. The electrode material of electric arc furnace is generally graphite electrode, anode and cathode graphite. Carbonization furnace: charcoal is burned in the furnace to generate carbon and oxygen, and the generated flue gas enters the molten pool after cooling, and the molten steel is discharged outward at the same time. Rotary Kiln: A reduction kiln is used in the smelting process for smelting metals or alloys.
Due to its excellent physical and mechanical properties, graphite electrodes can meet various special requirements, such as working under high temperature and vacuum conditions.
As a metallurgical furnace refractory material, graphite electrodes are widely used in electric arc furnaces, carbonization furnaces and rotary kilns, etc., and mainly play a protective role in smelting, especially in carbon steel smelting.
