The Mill Load application is specifically developed for mill design/operation engineers to calculate roll separating force, rolling torque and power, etc. Typically, load calculation is needed for an existing mill when a new rolling process is applied either with higher reduction or in lower temperature or higher speed, or for a stronger material. This is to make sure the force, torque, etc ...

A BASIC UNDERSTANDING OF THE MECHANICS OF …

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 ...
