Alumina magnesite carbon brick is made from high quality bauxite, corundum, and fused magnesia. It has low thermal conductivity, good isolation ability, and appropriate residual expansion. It is mainly used for ladle side walls and bottoms.
Alumium-magnesia Carbon Bricks is used fused alumina, bauxite high clinker, spinel sand, fused magnesia, graphite flake as raw materials , phenolic resin as binder, add a variety of antioxidant compound , And other additives, as high pressure forming of the non-burning products...
