Rolling [SubsTech]

A typical rolling mill consists of a pair of rolls driven by an electric motor transmitting a torque through a gear and pair of cardans The rolls are equipped with bearings and mounted in a stand with a screw-down mechanism A force applied to the rolls in vertical direction is called roll separating force A rolling mill is characterized by the maximum values of its roll separating force and

A BASIC UNDERSTANDING OF THE MECHANICS OF ROLLING MILL

Rolls are tools used in rolling mills to reduce the cross section of metal stock The weight of rolls may vary from a few kilograms up to 250 tonnes Under rolling conditions the contact area between roll and stock suffers wear the other parts of a roll - body and necks - have to be considered as normal parts of designed components under high load This means that necks should not experience
