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.
Off-set 8-Hi Strip Mill is driving by support roller, deviation 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.
Compared with the 4-hi rolling mill, the off-set 8-hi rolling mill requires the rolling force only half of the 4-hi rolling mill.
The off-set 8-Hi mill with a rigid structure of the larger roller system and roll shaped adjusting device. Which can be rolled out the strip steel with thickness deviation smaller and flat shape straight.
