How to Obtain Rolling Torque? Metals

The torque is obtained by integrating the frictional force multiplied by roll radius over the arc of contact (lagging and leading zones). The negative sign before the second term is due to the fact that in leading zone the metal moves faster than the rolls hence it helps to rotate the rolls.

Between Brews: Mounting and Motorizing Your

06-07-2018  The motor must have sufficient torque to keep the mill rollers operating smoothly under load. When motorizing your mill, you need to have it either operate at a relatively low rpm (200 rpm is about right) or have a reduction system added to achieve the correct rate. DC motors can be speed controlled but this adds complexity and reduces available torque.

Basics of Rolling and Rolling Mills – IspatGuru

Power which is applied to the rolling mill by applying a torque to the rolls and by means of work piece tension. The power is spent principally in four ways namely (i) energy needed to deform the metal, (ii) energy needed to overcome the frictional force, (iii) power lost in the pinions and power transmission system, and (iv) electrical losses in the various motors and generators.
