Abstract
In a rolling mill wherein product is rolled continuously in successive first and second blocks at the finishing end of the mill, a pinch roll unit is interposed between the two blocks. The motor speed of the pinch roll unit is employed in combination with other variables to preset the motor speed of the second block prior to entry of the product front end therein. The preset motor speed of the second block produces an acceptable level of interblock product tension once the product has entered the second block. Thereafter, product elongation in the first block is monitored and required adjustments to the motor speed of the second block are made in order to maintain interblock product tension within acceptable limits.
