Corundum plastic refractory is a type monolithic refractory material in clay lump or agglomerate shape. Wear resistant plastic refractory are usually rammed, vibrated or pressed when applied into construction or repair process. So corundum plastic refractory is very convenient and economical. Abrasion resistant plastic refractory raw material includes: chromium corundum and silicon carbide aggregate, power or liquid binder and additives. Wearable corundum plastic refractory has excellent high temperature abrasion resistance and chemical erosion resistance, is very suitable for circulating fluid bed boiler cyclone, furnace wall lining and parts where coal ash and slag impact is severe.
Corundum Plastic Refractory Features
High temperature abrasion resistance, chemical erosion resistance.
Thermal shock resistance, high rupture modulus.
Good plasticity, good palling resistance, long service life.
Convenient for application, can be rammed or painted directly.
High temperature stability.
