Description of LZ-48 LZ-55 LZ65 LZ 70 LZ75 LZ80 High Alumina Refractory Brick for Hot Blast Stoves

High Alumina Bricks are a type of refractory brick made with a high content of alumina, typically over 48%. This gives the bricks excellent high-temperature resistance, thermal shock stability, and low thermal conductivity.

High Alumina Bricks are manufactured by mixing alumina-rich raw materials, such as bauxite and kaolin, with water and other additives. The mixture is then molded into bricks and fired at high temperatures.
