Abstract
A continuous rolling mill capable of rolling a sheet metal under a reduced rolling force without wrapping it around work rolls wherein, at each of rolling stands, the upper and lower work rolls are rotated at different peripheral speeds in such a way that the peripheral speed of one of said pair of rolls which is rotated faster than the other may be substantially equal to the velocity of the metal sheet leaving said pair of rolls while the peripheral speed of said other roll which is rotated slower than said one roll may be substantially equal to the velocity of the metal sheet entering the pair of rolls.
