Idiostncratic

The main physical and chemical properties of the material are equivalent to the corresponding low cement and ultra-low cement castable. Its remarkable characteristic is that it can flow and degassing, the structure is uniform and the durable performance is good.

Scope of application

Can be used for heating furnace, soaking furnace, tundish permanent lining, etc.
