Andalusite Mullite Refractory Castable Gray Color For Furnace Liner
Product Introduction
high performance high alumina low cement refractory insulating castable for cement kilns is a kind of unshaped refractory made of granular and powdery material, in which add a certain amount of binder and water together. It has high mobility, is suitable for casting construction, and can be hardened without heating. Refractory castables consist of refractory aggregates, powders, binders, admixtures, water or other liquid materials. Generally in the use site, it is molded by pour, vibration or tamping method, and can be used as preforms. Refractory castables are mainly used in the metallurgical industry furnace, also in the petroleum, chemical, building materials, power and machinery industry furnace and thermal equipment.
