Description
Technical Field
The invention relates to a blast furnace structure, in particular to a blast furnace sealing mechanism with stable connection.
Background
The blast furnace uses steel plate as furnace shell, and refractory brick lining is built in the shell. The blast furnace body is divided into a furnace throat, a furnace body, a furnace waist, a furnace belly and a furnace hearth 5 from top to bottom. Because of the advantages of good economic index, simple process, large production capacity, high labor production efficiency, low energy consumption and the like of the blast furnace ironmaking technology, the iron produced by the method accounts for the vast majority of the total iron production in the world. In the production of a blast furnace, iron ore, coke, and a flux (limestone) for slag formation are charged from the top of the furnace, and preheated air is blown through tuyeres located along the periphery of the furnace at the lower part of the furnace. Carbon in coke (some blast furnaces also blow auxiliary fuel such as coal dust, heavy oil, natural gas and the like) at high temperature is combusted with oxygen blown into air to generate carbon monoxide and hydrogen, and oxygen in iron ore is removed in the ascending process in the furnaces, so that iron is obtained by reduction. The smelted molten iron is discharged from the iron notch. Unreduced impurities in the iron ore are combined with fluxes such as limestone to generate slag, and the slag is discharged from a slag hole. The generated gas is discharged from the top of the furnace, and is used as fuel for hot blast stoves, heating furnaces, coke ovens, boilers and the like after dust removal. The main products of blast furnace smelting are pig iron, and blast furnace slag and blast furnace gas are also by-products.
