The blast furnace uses steel plates as the furnace shell, and the shell is lined with refractory bricks. The blast furnace body is divided into 5 parts from top to bottom: furnace throat, furnace body, furnace waist, furnace belly and furnace hearth. Due to the advantages of good technical and economic indicators of blast furnace ironmaking, simple process, large production volume, high labor production efficiency and low energy consumption, the iron produced by this method accounts for the vast majority of the world's total iron output.


During the production of blast furnace, iron ore, coke, slag-making flux (limestone) is loaded from the top of the furnace, and preheated air is blown in from the tuyere located at the lower part of the furnace along the furnace periphery. At high temperatures, carbon in coke (some blast furnaces also spray auxiliary fuel such as pulverized coal, heavy oil, natural gas, etc.) burns with carbon monoxide and hydrogen produced by the oxygen blowing into the air to remove iron ore during the ascent in the furnace Oxygen, thereby reducing iron. The molten iron is released from the iron mouth. Unreduced impurities in iron ore combine with flux such as limestone to form slag, which is discharged from the slag port. The produced gas is discharged from the top of the furnace, and after dedusting, it is used as fuel for hot air furnace, heating furnace, coke oven, boiler, etc. The main products of blast furnace smelting are pig iron, as well as by-product blast furnace slag and blast furnace gas.
