Al2O3 SiC C Brick Details

Al2O3 SiC C brick refers to the non-burnt carbon composite refractory material that uses AL2O3, SiC and carbon raw materials as the main components and synthetic phenolic resin as the binder. The production of Al2O3 SiC C mainly includes fused corundum, sintered corundum, alumina clinker, andalusite, silicon carbide, graphite and other additives. In addition, a certain amount of fused magnesia is added to the matrix, so that the brick forms spinel during the application process, and has residual expansion properties, and improves the thermal strength, thereby enhancing the brick's corrosion resistance.It is mainly used for lining of hot metal pretreatment equipment such as torpedo-type mixed iron trucks and hot metal tanks. AL2O3 SiC C brick has excellent slag resistance and thermal shock resistance, as well as good erosion resistance and wear resistance. It is by far the most ideal lining material on hot metal pretreatment containers.

Production Process：

Adding carbon raw materials to the main alumina raw materials, adding a small amount of other raw materials such as silicon powder, SiC powder, aluminum powder, etc., using phenolic resin or asphalt as a binder, after batching, mixing , Isostatic pressing (or machine pressing), firing in a reducing atmosphere.

Features

High refractoriness.

Good spalling resistance and wear resistance.

Good corrosion resistance.

Good thermal shock resistance.

High mechanical strength.
