China Common Lightweight Thermal Insulating Castable, Find details about China Refractory, Castable from Common Lightweight Thermal Insulating Castable
Common light adiabatic castable The castable mixture prepared by light refractory aggregate and powder, binder and admixture is called light castable.
Features:
Small volume density, low thermal conductivity, can reduce the weight of equipment, good heat preservation performance, make the furnace temperature uniform, energy saving, high fire resistance, strong overall performance, good spalling resistance, long service life, can be arbitrarily repair and not process all kinds of shapes or overall lining.Construction is simple, low cost, has been widely used in metallurgy, machinery, electric power, chemical, petroleum and other industries of industrial furnaces and thermal equipment.
