Hot Strip Mill

For the roughing mill (reversible 4-high) both roll force and roll torque were available so the friction coefficient could be evaluated in addition to the flow stress for each pass. The values were close to 0.3 so it was decided to use this for all calculations, also for the finishing, six-stand (4-high), tandem mill.
