  • A BASIC UNDERSTANDING OF THE MECHANICS OF ROLLING MILL ROLLS

    A BASIC UNDERSTANDING OF THE MECHANICS OF ROLLING MILL ROLLS

    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 ...
