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 ...

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 ...
