Corundom Castable Mix
It is a castable mixture made of light refractory aggregate, powder, binder and additive. Because of the small volume density and low thermal conductivity of light castables, it is also known as insulating refractory castables. Light castables are divided into semi-light refractory castables, light refractory castables and ultra-light refractory castables according to volume density, and low-temperature insulation (light) refractory castables, medium-temperature insulation (light) refractory castables, high-temperature insulation (light) refractory castables according to end-use temperature. The main used part are furnace roof, furnace wall and insulation layer in the furnace. It has good thermal insulation, can inhibit the heat radiation and heat transfer loss of high-temperature objects, has a significant energy-saving effect.
