STANDARD DENSE CASTABLES & GUNNING MIXES
VITCAST 1800STD & GUN MIX
VITCAST 1700STD & GUN MIX
Tabular alumina based castable with high chemical purity, high strength, impact resistance and abrasion resistance up to 1850 O C in suitable atmospheres. Examples of Applications: Used in the petrochemical industry and fertiliser production industry. Also in situations where the temperature can be low but the materials are very aggressive such as melting of copper and brass.
Fused aggregate and chrome alumina based refractory castable for molten metal contact at temperatures up to 1700 O C.
Examples of Applications: Used for containing molten iron and for spouts and launders where extreme temperatures and abrasion make extremely arduous conditions.
