1550C Cupola Furnace Iron Melting furnace Steel Melting Furnace for Making Steel
Cupola is an important equipment for melting cast iron in foundry production. The cast iron block is melted into molten iron and then poured into the sand mold to be cooled and then opened to obtain castings. Cupola is a vertical cylindrical smelting furnace, which is divided into front furnace and rear furnace. The forehearth is further divided into a tap hole, a slag outlet, a hearth in front of the furnace cover and a bridge. The rear furnace is further divided into three parts, the top furnace, the waist furnace and the hearth. The waist furnace is separated from the hot air surrounding pipe, closed after repairing the furnace, and sealed with mud. On the top furnace is a heat exchanger. It is mainly used in the production of cast iron castings, and is also used in conjunction with converter steelmaking. Because the top of the furnace opens upward, it is called a cupola furnace.
work process:
First put a certain amount of coal into the furnace as bottom coke, and its height is generally more than one meter. After ignition, add the bottom coke to the specified height, from the tuyere to the top surface of the bottom coke is the bottom coke height. Then according to the melting rate of the furnace, the prepared limestone, metal charge and layer coke are added in batches from the feeding port in order. Keep the top surface of the charge at the lower edge of the charging port during the entire furnace opening process. The air blown into the furnace through the tuyere undergoes a combustion reaction with the bottom coke, and the generated high-temperature furnace gas flows upward to heat the charge and melt the first batch of metal charge on the top surface of the bottom coke. As the molten iron droplets fall to the hearth, they are further heated by the hot furnace gas and the hot coke, a process called superheating. With the loss of bottom coke and the melting of metal charge, the charge layer gradually declines. After each batch of charge is melted, the fuel is supplemented by the additional layer coke, so that the height of the bottom coke remains basically unchanged, and the whole melting process is carried out continuously. Application field: Cupola is mainly used in steel, metallurgy, mining and other industries.
