Refractory Castable

  • Product Description:

    The mixture composed of refractory aggregate, binder and admixture, mixed with water (or liquid binder) into the construction of the mud available pouring method is called refractory castable.There is a certain setting and hardening time after the construction of the refractory castable, so the mold can only be removed after a certain time of curing after pouring molding, and then after a proper time of natural curing can be put into baking use.
  • Application Field:

    Refractory castables are widely used in power plant CFB boiler, molten aluminum furnace, intermediate frequency furnace, coreless induction furnace, rotary kiln and other industrial furnaces.
