Refractory castable refers to the mixture composed of refractory aggregate, binder and admixture, mixed with water (or liquid binder) into the construction of the method of pouring mud.
The difference with other amorphous refractories lies in that the refractory castable has a certain setting and hardening time after construction, so after pouring molding needs to go through a certain time of curing before demoulding, and then after a proper time of natural curing can be put into baking use.
