Roll Torque - an overview | ScienceDirect Topics

The speed of the rolling mill is set at 10 rpm, giving a roll surface velocity of 70.69 mm/s. It was found necessary to use guides for the bars, both at entry and exit, in order to minimize sideways bending. The parameters monitored during the experiments include the temperature, roll force and torque.
