Admite Roll

Admite roll’s feature is between the cast iron roll and cast steel roll. It’s not only high strength and toughness feature of cast steel roll, but also good wear resistance of cast iron roll. For best features, it’s made by special and long time heat treatment.

Widely used on section steel mills, hot strip rolling mill, roughing stand, medium stand & pre-finish stand of bar and wire mills. For good performance, the fine water cooling is the must for admite rolls working.
