Explanation

Also called cupola, it is a cylindrical shaft furnace for smelting cast iron. III Furnace body support part (furnace base, furnace legs, furnace bottom door), furnace body (furnace bottom, furnace hearth, furnace body), furnace top (chimney, dust collector) Air supply system (Composed of blower, air duct, air belt, tuyere and front furnace, etc. Compared with electric arc furnace, induction electric furnace, reverberatory furnace and other equipment, the cupola has the advantages of simple structure, convenient operation, rapid melting, strong adaptability, continuous production and low cost; it is more difficult to improve the temperature of cast iron and adjust the chemical composition with cupola melting, and alloy burning loss is large, so the cupola and electric furnace double melting are also used to complement each other's advantages The melting of cast iron in the furnace can be divided into three processes: coke combustion process; Preheating and melting of metal charge and overheating of molten iron; Interaction process of furnace gas, slag, molten iron and coke. The nominal tonnage of the cupola is the tonnage of molten iron per hour. The nominal diameter is the inner diameter of the furnace of the melting zone.
