High strength wear-resistant refractory castable for boiler 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 castable 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 castable are mainly used in the metallurgical industry furnace, also in the petroleum, chemical, building materials, power and machinery industry furnace and thermal equipment.
