Description
Technical Field
The invention relates to the technical field of steelmaking equipment, in particular to an energy-saving cupola furnace.
Background
The cupola furnace is an important equipment for melting cast iron in casting production, and cast iron blocks are melted into molten iron, poured into a sand mold, cooled and opened to obtain a casting. The cupola furnace is a vertical cylindrical smelting furnace, which is divided into a front furnace and a rear furnace. The forehearth is divided into a tap hole, a slag hole, a furnace cover forehearth and a gap bridge. The rear furnace is divided into three parts, a top furnace, a waist furnace and a furnace hearth. The waist furnace and the hot blast bustle pipe are separated, closed after the furnace is repaired, and sealed by mud. On the top furnace is a heat exchanger. It is mainly used for producing iron castings and is also used for matching converter steelmaking, so the cupola furnace is called because the opening of the furnace top is upward.
The working process of the cupola furnace is that a certain amount of coal is firstly loaded into the furnace as bottom coke, and the height of the bottom coke is generally more than one meter. After ignition, the bottom coke is added to a specified height, and the height from the tuyere to the top surface of the bottom coke is the bottom coke height. Then, the prepared limestone, metal furnace charge and coke layer are added from the feed opening in sequence and in batches according to the melting rate of the furnace. The top surface of the furnace charge is kept under the charging opening in the whole furnace opening process. The air blown into the furnace through the tuyere and the bottom coke are subjected to combustion reaction, the generated high-temperature furnace gas flows upwards to heat the furnace burden, and the first batch of metal furnace burden on the top surface of the bottom coke is melted. The molten iron droplets are further heated by the hot furnace gases and hot coke in the process of falling into the hearth, which is called superheating. The bed of material gradually descends as the bottom coke is burned off and the metal charge is melted. After each batch of furnace burden is melted, the fuel is supplemented by the added layer coke, so that the height of the bottom coke is basically kept unchanged, and the whole melting process is continuously carried out. The cupola furnace is mainly applied to industries such as steel, metallurgy, mine and the like.
