Product definition
Refractory castable is a mixture of refractory aggregate, binder and admixture, mixed with water (or liquid binder) into mud can be cast method construction called refractory castable.
Matters needing attention
The refractory castable has a certain setting and hardening time after construction, so the mold can be removed after a certain time of curing after pouring molding, and then it can be put into baking use after a proper time of natural curing.
Application field:
Refractory castable is widely used in power plant CFB boiler, aluminum melting furnace, medium frequency furnace, coreless induction furnace, rotary kiln and other industrial kilns.
