Blast Furnace Steelmaking
Steelmaking refers to the process of transforming iron ore into steel with specific chemical composition and properties through a series of smelting processes by controlling temperature, pressure and chemical reaction. Steelmaking not only provides high-quality materials for various industrial fields to meet the needs of different applications, but also promotes the effective utilization of resources, environmental protection and sustainable economic development.
Blast Furnace Cylinder (Furnace Belly)
The furnace cylinder is the main combustion area of the blast furnace and is subject to high temperatures and pressures. Refractory bricks, usually high alumina refractory bricks, are used in the inner wall of the furnace cylinder because they have high refractoriness and erosion resistance and are able to resist chemical erosion and mechanical wear at high temperatures.
Lower part of the blast furnace cylinder (furnace floor)
The bottom of the furnace is the melting area of the blast furnace and is subject to high temperatures and erosion from smelting slag. The bottom of the furnace usually uses carbon bricks or magnesium-carbon bricks as refractory materials. These bricks have high refractoriness and erosion resistance, and are able to withstand chemical corrosion and smelting slag erosion at high temperatures.
Upper part of the blast furnace (furnace throat and roof)
The throat is the gas outlet of the blast furnace and the roof is the upper closed structure of the blast furnace. The throat and roof need to withstand high temperatures and high thermal shock conditions, so refractory materials such as high alumina refractory bricks, carbon bricks, and silicon carbide bricks are used. In addition, the top of the furnace has openings and venting devices, which are usually made of refractory materials such as carbon bricks, carbonaceous materials and ceramic fibers.
Blast furnace interior (walls and body)
The interior of the blast furnace is the main area where iron ore is reduced and steel is made. The furnace walls and body need to have high refractoriness, erosion resistance and thermal conductivity. Commonly used refractory materials include high alumina refractory bricks, magnesium bricks and carbon bricks.
Blast furnace air opening (slag opening)
Blast furnace air vent is the key part to control the inlet and outlet of the blast furnace and the discharge of gases. The air opening needs to withstand high temperature and smelting slag erosion, and refractory materials such as carbon bricks and silicon carbide bricks are usually used.
