Lightweight corundum bricks are widely used in various high-temperature thermal equipment and industrial scenarios due to their high temperature resistance, good thermal insulation and low bulk density.

Blast Furnace and Hot Blast Stove - Lightweight corundum bricks are used as insulation layers or linings in blast furnace bodies, regenerators, combustion chambers and other parts of hot blast stoves to reduce heat loss while withstanding the long-term effects of high-temperature flue gas.
Ladle and Tundish - used in the permanent layer of the ladle and the insulation structure of the tundish to reduce the heat dissipation of the ladle and improve the thermal insulation effect of molten steel.
Steel Rolling Heating Furnace - used for the insulation layer of the furnace roof and furnace wall, adapting to the high temperature environment in the heating furnace and reducing the weight of the furnace body.
Ceramic Tunnel Kiln and Roller Kiln - as the inner lining or thermal insulation layer of the kiln, especially in the high-temperature firing zone, they can withstand the high temperature during the firing of the green body, while reducing the heat dissipation from the kiln body and reducing energy consumption.
Glass Kiln - used in the furnace waist, furnace bottom, heat storage chamber and other parts. It can not only withstand the high temperature during glass melting, but also maintain the temperature inside the furnace stable through thermal insulation performance and reduce heat loss.
Chemical Reactor - in synthetic ammonia converters, gas generators and other equipment, it is used as a thermal insulation lining to resist indirect erosion from high temperatures and corrosive gases during the reaction process.
Waste Incinerator - lightweight corundum bricks are used for the thermal insulation layer of the furnace body, adapting to the high temperature of 800-1200℃ during the incineration process and withstanding the indirect effects of complex components in the flue gas.
Waste heat Boiler - used in the insulation structure of the high-temperature flue gas channel to improve the waste heat recovery efficiency and reduce the heat diffusion to the outside.
Laboratory High Temperature Furnace - used as the lining or insulation layer of box furnace and tube furnace to meet the high temperature requirements of material sintering, heat treatment and other experiments.
The Thermal Insulation Layer of Non-ferrous metal smelting furnaces, such as aluminum electrolytic cells and copper smelting converters, is adapted to the high temperature environment during the smelting of molten aluminum and copper.
High Temperature Pipe Insulation - used for the outer insulation of pipes that transport high-temperature flue gas and hot air, reducing heat loss in pipes and protecting external structures.
Tips: Lightweight corundum bricks have a higher porosity, and their slag erosion resistance and mechanical strength are lower than those of dense corundum bricks. Therefore, they are not suitable for direct contact with molten metal, large amounts of slag or highly corrosive media. They are mainly used in scenarios where insulation and heat preservation are the core requirements, and where gas or indirect high temperature effects are the main factors. When selecting a model, a comprehensive judgment must be made based on the temperature, force, and medium environment of the specific equipment.
