Rolling processes

Rolling processes 5-1 introduction this point slipping and friction occur between roll and work The amount of slip between the rolls and the work can be measured by means of the forward slip a term used in rolling that is defined 5 5 Where s = forward slip v f = final (exiting) work velocity m/s (ft/sec) and v r = roll speed m/s (ft/sec) The rolls pull the material into the roll Get price
