Product Introduction
Chrome corundum castable is a high-performance amorphous refractory material. It is mainly composed of refractory aggregates such as chrome corundum, corundum, aluminum chrome spinel, special binders (such as pure calcium aluminate cement, phosphoric acid or aluminum dihydrogen phosphate, etc.) and additives.
These ingredients make chrome corundum castable have excellent high temperature resistance, wear resistance, corrosion resistance, slag resistance and other characteristics, so it has been widely used in high-temperature equipment in metallurgy, petrochemical and other industries.
Rongsheng can produce refractory castables of different strength grades according to customers’ specific needs.
