Blast Furnace Ironmaking Refractory Solutions

Bottom: The bottom of the blast furnace, where the molten iron metal (molten iron) and slag are collected. The bottom of the furnace is usually made of high alumina bricks and silicate bricks with good refractory and corrosion resistance.

Furnace Body: Above the bottom is the body of the blast furnace. The furnace wall is the main component of the blast furnace body, which is a cylindrical structure mainly divided into three zones: high-temperature zone, medium-temperature zone and cooling zone.

High-temperature zone: In the high-temperature zone, the commonly used refractory bricks include high alumina bricks and silicate bricks. High-alumina bricks have excellent refractory properties and erosion resistance, while silicate bricks are also used in some special cases.

Medium temperature zone: Refractory bricks for medium temperature zones are usually silicate bricks, which can adapt to higher temperatures and chemical environments.

Cooling zone: Refractory bricks or other refractory materials are used in cooling zones to resist lower temperatures and mechanical stresses.

Furnace throat: The throat is the transition area between the furnace body and the furnace seal. The throat is generally made of carbon bricks, which can withstand high temperatures and impacts and have good thermal conductivity.

Seal: Above the throat is the seal of the blast furnace, which is a conical structure usually made of high alumina bricks or silicate bricks capable of withstanding high temperatures and chemical attack.

Top of Blast Furnace: Above the seal is the top of the blast furnace, which usually also includes the desulfurization equipment, gas treatment equipment and chimney. Generally use high alumina bricks, silicate bricks and refractory castables.
