ABSTRACT:
A set-up method for unequal speed circumferential rolling. The setting values of the circumferential speeds of a higher speed roll and a lower speed roll and the roll position are obtained by using, as rolling parameters in a rolling schedule, the inlet and outlet thicknesses, the forward and backward tensions, the radii of the rolls, the frictional coefficients and the ratio of the circumferential speeds of the rolls. The setting values are computed such that these values meet the rolling conditions within both the load limit value and the tension limit value.
