ABSTRACT:
A rolling mill capable of rolling a sheet metal into a final product under a low rolling pressure without the need of wrapping the sheet metal around a pair of work rolls. The pair of work rolls are rotated at different peripheral velocities, and the tensions exerted to the sheet metal entering and leaving the pair of work rolls as well as the degree of reduction are so controlled that the ratio of the peripheral velocity of one of the pair of work rolls which is rotated faster than the other work roll to the peripheral velocity of the other work roll may be substantially maintained equal to the elongation ratio of the thickness of the metal sheet entering the pair of work rolls to the thickness of the metal sheet leaving the work rolls.
