High aluminum firebrick, that is, alumina content in more than 48 percent of a kind of aluminum silicate refractory. It is made by forming and calcination of bauxite or other raw materials with high alumina content. Generally, high alumina bricks are made of good bauxite clinker, combined with clay and additives. The refractoriness is above 1750℃. In the process of making high alumina firebrick, the corresponding technology is added to magnify the advantages of high alumina firebrick.

High aluminum refractory brick application field:

1. Steel manufacturing industry: blast furnace, hot blast furnace, electric furnace, ladle, tundish, heating furnace, refining furnace, heating furnace, annealing furnace, cupola furnace;

2. High-aluminum refractory brick non-ferrous metal industry: smelting furnace, refining furnace, reverberatory furnace, converter;

3. Building materials industry: high-aluminum refractory brick cement kiln, glass kiln, ceramic kiln, lime kiln, kiln car, tunnel kiln;

4. High aluminum refractory brick energy and incineration: coke oven, circulating fluidized bed boiler, carbon roaster, incinerator

High aluminum firebrick, that is, an aluminum silicate refractory with an alumina content of more than 48 percent. It is made of alumina or other raw materials with high alumina content by molding and calcination. High thermal stability, refractories above 1770℃. Good slag resistance.
