Use stiffer rolls, namely roll material of high stiffness or elastic constant, we could avoid mill spring.Normally elastic constant for mills may range from 1 to 4 gnm-1.Roll elastic deformation may result in uneven sheet thickness across.Roll material should have high elastic modulus for reducing the roll def ormation.

The higher the precharge pressure the softer the spring rate.A low precharge pressure will make the system very stiff and may not allow sufficient float to let tramp iron through the mill, which may cause damage.A high precharge pressure will make the system very soft and the top roll bearing may continually rise up to its maximum lift.

A z-mill or sendzimir mill is a machine for rolling steel.Unlike a traditional rolling mill this 20-high cluster mill configuration utilizes cascaded supporting rolls to apply force on the small work rolls in the center.This allows the application of a higher roll pressure without bending the work rolls, which would result in poor metal quality.
