Forged steel backup rolls for hot and cold rolling mills

One-piece-forged backup rolls, sleeves of composite backup rolls are manufactured from carbon, high-carbon, tool and alloy steels, that provides rolls with high hardness and wear resistance. All backup rolls are manufactured from vacuum degassed steel. The uniform hardness after tempering on CFC (commercial frequency current) unit and high material strength in combination with ductility property are provided by means of complex chromium, molybdenum, vanadium or other elements alloying.
