High-alumina insulating bricks are insulating refractory material primarily made from high-alumina bauxite clinker. It features high refractoriness and excellent thermal insulation properties. It is widely used in high-temperature insulation applications in industries such as steel, glass, ceramics, and cement. · High Refractoriness: Suitable for high-temperature environments due to its high refractoriness. · Excellent Thermal Insulation: Effectively reduces heat loss, improving energy efficiency. · High Compressive Strength: Possesses sufficient mechanical strength to withstand certain loads.
Steel Industry: Used in the high-temperature insulation layers of blast furnaces and hot blast stoves.
Glass Industry: Applied in high-temperature insulation areas of glass furnaces.
Ceramics Industry: Used in the high-temperature insulation layers of ceramic kilns.
Cement Industry: Utilized in high-temperature insulation areas of cement rotary kilns.
