Refractory Bricks Manufacturer

Special grade high alumina brick is a dense special grade high alumina brick with high compressive strength and high density. The firing temperature of this  high-alumina brick is similar to that of ordinary high-alumina bricks, with low energy consumption and low cost. Its service life in the kiln is twice that of ordinary high- alumina refractory bricks . It uses special-grade bauxite clinker calcined in a rotary kiln as aggregate, with a particle size of 1smm to 3smm. Weight ratio: 40% to 45%, adding bauxite clinker powder and fine powder: 45% to 51%. Soft clay: 7% to 10%, a small amount of kyanite powder: 3 to 5%. And it consists of 4% to 5% of adhesive pulp waste liquid. During production, the bauxite clinker needs to be crushed and sieved, and the powders are mixed and ground together. After batching, mixing, shaping, and drying, it is fired into refractory bricks at 1440~1460℃. Special Grade High Alumina Brick Special grade high alumina bricks are high alumina refractory bricks
