Description

Castable Refractory is a kind of material made by mixing the granular and powdered materials with a certain amount of binder composition and water together.

It is an amorphous refractory with high mobility, it can be used with casting method of construction but be hardened without heating.

It is made from refractory aggregate, powder, binder, additives, water, or other liquid material.

In general it can be used with molding method of site casting, vibrating or tamping, also a preform can be made in use.
