ABSTRACT:
A rolling mill wherein a pair of upper and lower work rolls are rotated at different peripheral velocities with the peripheral velocity ratio being substantially equal to an elongation ratio at which a sheet metal is rolled, and the tensions exerted to the sheet metal entering and leaving the pair of work rolls are controlled in such a way that the velocity of the sheet metal entering the work rolls may be maintained equal to the peripheral velocity of one of the pair of work rolls which is rotated slower than the other while the velocity of said sheet metal leaving the work rolls may be maintained equal to the peripheral velocity of said the other work roll. Rolling may be accomplished without the need of wrapping the sheet metal around the work rolls, and the rolling pressure may be reduced to a degree comparable RD process.
