Refractory castable is a kind of granular and powdery material made of refractory material with a certain amount of binder. It has high fluidity and is formed by casting.
Refractory castable is a kind of granular and powdery material made of refractory material with a certain amount of binder. It has high fluidity and is formed by casting.
Compared with other amorphous refractories, the binder and moisture content are higher and the fluidity is better, so the castable has a wide range of applications, and the materials and binders used can be selected according to the conditions of use. It can be directly cast into a lining body, or can be used as a prefabricated block by casting or shaking.
