Cement Furnance Ladle Refractory Castable

Product introduction of ladle refractory castable

The ladle refractory castables are made of high-quality high-alumina bauxite, corundum and high-quality magnesia as the main materials, and appropriate amount of binder and additives (dispersant, water reducer) are added.

Features of ladle refractory castable

Ladle refractory castables have good slag resistance and peeling resistance, high volume stability, high strength and short sintering time.
