Product Introduction
Corundum plastic is a kind of amorphous refractory material in the form of mud or mud balls constructed by ramming, vibration or pressing. This material has the characteristics of good plasticity, long shelf life, and strength increasing with increasing temperature, and has high strength and wear resistance.

Application Of Corundum Plastic
It is widely used in furnace linings, cyclones, heat radiation materials and other parts that require refractory materials in the power, metallurgy, steel, ceramics and other industries.
It is particularly suitable for the construction and rapid repair of circulating fluidized bed boiler linings, as well as the use of circulating fluidized bed gasification furnaces, biomass gasification furnaces and other furnace linings.
