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,CVC ® plus bending and shifting systems in finishing,,12.06.2018· Within the next few years, the CVC ® system was integrated in a large number of various types of hot rolling mills due to its simple and efficient operating principle combined with robust and reliable mechanical equipment.
