8-Hi Strip Rolling Mill is driven by support roller, deviated from the work roll bearing roll center installation. So that the reduction of the diameter of the work rolls is not limited by the torque, and is not affected by horizontal bending. Therefore, the work roll diameter can be small, usually half of the four-roll mill work roll diameter, this off-set 8 hi rolling mill can meet the requirements of rolling thin steel and rolling difficult-to-deform products like the cluster mill.
