Hot blast stove checker bricks are a type of heat-carrying and heat-storing body, characterized by good volume stability, excellent high-temperature load creep performance, high density and low porosity.
Checker bricks are currently a heat-carrying and heat-storing body recognized and accepted by the world's ironmaking industry, with many thermal characteristics such as strong heat exchange ability, large heat storage area, smooth ventilation and low resistance. Checker bricks are a heat transfer medium, mainly used in the middle and upper parts of the hot blast stove regenerator. They play a heat storage role and are of great importance in the process of heating cold air into hot air.
Applications of hot blast stove checker bricks: Checker bricks are mainly used in hot blast stoves. When the hot air temperature is below 900℃, clay bricks are generally selected; when the air temperature is above 900℃, high-alumina bricks, mullite bricks, sillimanite bricks and silica bricks are used for checker bricks.
