Corundum ramming material is a clay billet or an amorphous mortar constructed by ramming, vibrating or pressing.Refractory aggregate, powder, binder, admixture or other liquid with certain grade.Press refractory orthopaedic material to be divided into: clayey qualitative, high aluminous qualitative, rigid jade qualitative, siliceous qualitative, magnesian qualitative, chromic qualitative, zirconia is qualitative and carborundum is qualitative refractory but plastic.According to the type of binder is divided into: sodium silicate, phosphate and binder refractory plastics, etc.According to the way of hardening, there are gas rigid or thermal rigid refractory plastic two.

Corundum refractory plastic is made of wear-resisting raw material as aggregate, combined with powder or liquid binder and mixed with some additives. It is a plastic with excellent wear-resisting ability at high temperature.this product is suitable for circulating curing bed boiler cyclone tube, furnace wall lining and coal ash impact and serious parts.
