Load torques which always oppose the motion and change their sign on the reversal of motion are called passive load torques. Torque due to friction cutting – Passive torque. Components of load torques: 1. Friction Torque (TF) The friction torque (TF) is the equivalent value of various friction torques referred to the motor shaft. 2. Windage Torque (Tw) When a motor runs, the wind generates a ...

Roll stands holding pairs of rolls are grouped together into rolling mills that can quickly process metal, typically steel, into products such as structural steel (Ibeams, angle stock, channel stock), bar stock, and rails. Most steel mills have rolling mill divisions that convert the semifinished casting products into finished products.

Torque required to provide a certain level of tension to a web is total tension measured across the web times roll radius. This means the torque driving the unwind shaft must decrease at a linear ratio, relative to roll diameter, as an unwind roll decreases in size, through a machine run, to keep tension constant. Conversely, the torque driving the
