Product description
Castable refractory cement forge are castable refractory materials formulated with soft clay as the binding agent, alumina clinker, clay clinker or corundum, mullite, etc. as refractory aggregates and powders and additives. According to the types of refractory aggregates and powders used, castable refractory cement forge are divided into clay-based, high-aluminum, corundum-mullite, lightweight high-aluminum, etc. It has excellent properties such as good thermal expansion resistance and strong peeling resistance. Mainly used in thermal equipment such as high furnaces, soaking furnaces, and heating furnaces.
The type and dosage of clay binder have an important impact on its performance. The choice of soft clay binder requires good plasticity, strong dispersion, good adhesion, wide sintering temperature range, and high refractoriness.
Application of castable refractory cement forge
Castable refractory cement forge also called calcium clinker, is made from industrial alumina oxide powder and selected limestone powder. castable refractory cement forge is produced after manufactured under high temperature in rotary and grind into powder. High temperature castable refractory is for making high temperature good quality refractory castables, which is a basic furnace refractory materials used in high temperature facilities in industries like metallurgy, building material, chemical, electric plant, etc.
