What is refractory casting material

Refractory castable refers to a mixture of refractory aggregates, binders, and additives, mixed with water (or liquid binders) to form a slurry that can be used for pouring construction. The difference from other amorphous refractory materials is that the refractory casting material has a certain setting and hardening time after construction, so it needs to undergo a certain period of curing after casting to demould, and then natural curing for an appropriate period of time before it can be put into baking use.
