Ironmaking blast furnaces are commonly known as blast furnaces; The blast furnace generally refers to a vertical furnace for smelting non-ferrous metals.

1. The blast furnace can be used for matte smelting of metals such as copper, nickel, cobalt, and reduction smelting of metals such as lead and zinc. It can also be used for melting miscellaneous copper and processing other materials. The charge of a blast furnace is generally block shaped, and the fuel is coke. The cross-section of the blast furnace body is mostly rectangular, while small furnaces are generally circular or elliptical.

2. A circular iron making vertical furnace with a steel plate shell and a refractory brick lining inside. The main body of the blast furnace is divided from top to bottom into five parts: throat, shaft, waist, bosh, and hearth. Install charging equipment above the furnace throat (see the blast furnace feeding and charging system). The upper part of the furnace hearth is uniformly equipped with air vents along the circumference, and hot air is blown into the furnace through the air vent through the hot air enclosure, branch pipes, elbows, and direct blowing pipes (see blast furnace blowing system). There is a slag outlet below the air outlet plane, and an iron tapping hole below the slag outlet plane.
