High Alumina Brick Introduction:

     High alumina brick, also known as alumina lining brick, is a silicon-aluminum refractory material with aluminum oxide (Al2O3) content greater than 48%. It is made by molding and calcining bauxite or other raw materials with high aluminum oxide content. High alumina bricks are classified into special grade, first grade, second grade, and third grade.

High Alumina Brick Characteristics:

     This product has the characteristics of low temperature creep, strong resistance to erosion, good thermal shock stability, high thermal stability, and good slag resistance. It meets the high-quality and high-grade refractory materials required for China's new-type hot blast stoves, and has been included in the national "Spark Program" project.

Applications of High Alumina Brick:

     Because high alumina refractory materials have high refractoriness and high temperature mechanical strength, they are often used instead of high-quality clay bricks and silica bricks to improve the service life of furnaces. Currently, they are mainly used for constructing blast furnaces, hot blast stoves, electric furnace roofs, blast furnaces, reflector furnaces, rotary kiln linings, and firewalls for regenerators in glass furnaces. In addition, high alumina bricks are widely used as checker bricks for the regenerator of a flat furnace, as well as for stoppers and spouts in casting systems.
