| Properties
Forged steel rolls are treated with dual frequency heating machine and cold treatment equipment. The whole procedure is computer-controlled so as to provide rolls with a deep hardened layer, high and homogeneous hardness, superior wear ability and sufficient resistance to accident. We produce forged roll for rolling mills, specialized making kinds of steel forging and casting mill roll and back up roll.
