P. Kucsera et al. Hot Rolling Mill HGC Thickness Control Improvement 98 Another way to determine the thermal expansion of the work roll is the modelling of the heat transfer between the work rolls and the strip. This depends on the roll speed, strip thickness, the properties of the strip, roll gap, contact time and cooling parameters.
