Abstract
A rolling process wherein a pair of working rolls are driven at different peripheral velocities so that the peripheral velocity ratio may be varied, and the peripheral velocity ratio is so controlled that the rolling torque of each of the working rolls may be within a maximum tolerable torque which the working roll may transmit, thereby reducing the rolling force.
Claims1
A rolling process for a metal piece maintaining a peripheral velocity ratio between a pair of working rolls as high as possible but below a thickness ratio between the metal piece entering the working rolls and the same metal piece leaving the working rolls, whereby the rolling torque may be within a maximum tolerable torque.
