Magnesia Ramming Mass

Magnesia ramming mass is a bulk material made of fused magnesia, mixed with a variety of superfine powder additives, and fused cement or composite resin as a binder. The ramming material has good chemical stability, erosion resistance, abrasion resistance, peeling resistance, and heat shock resistance. It is widely used in metallurgy, building materials, non-ferrous metal smelting, chemical, machinery and other manufacturing industries.
