Load Analysis of Rolls in a Rolling Mill: A Comparison of ...

Rolls are the the most basic part in a rolling mill. Forces because of deformation of plate are transmitted to them directly, and then are transmitted to other parts like bearings, housings, etc. Rolls failure is a common problem faced by the rolling industry. It occurs due to overdraft which causes overloading, and also due to carrying out multiple passes without stress relieving the rolls in ...

POWER IN ROLLING - IDC-Online

The power in rolling process is expended principally in four ways: 1. The energy required to deform the metal. 2. The energy required to over come frictional force in bearings. 3. The energy lost in power transmission system. 4. The energy lost in the form of electrical losses in the motor etc., Torque and Power in Cold Rolling *Power is applied to the rolling mill by applying Torque to the ...
