Alumina-silicon-carbon

Alumina-silicon-carbon is a fire-lined product made of super high alumina bauxite or corundum sand, magnesia and flake graphite as the main raw materials. It is characterized in that in addition to the advantages of high corrosion resistance and not easy to peel due to carbon content at high temperature, it also has the advantage of showing high residual linear expansion rate due to the formation of spinel when heated during use, so it has become a newly developed high-quality product. Contains Al₂O₃ 60%~69%, MgO 7%~14%, C 5%~12%. It has good slag corrosion resistance and thermal shock resistance, and a small amount of reburning expansion.
