Abstract
PURPOSE: To flatly skin-pass roll various plate metal strips without middle waviness and edge waves by matching the peripheral speed of one of upper and lower rolling rolls of a fixed roll curve to the product speed after rolling and controlling the peripheral speed of the other to the speed of the specific range.
CONSTITUTION: In rolling the rolling material 3 of a thickness h1 with rolling rolls 1 and 2 on the upper and lower sides to a product 4 of a thickness h2, the peripheral speed n2 of the roll 2 is controlled to the speed between the speed v1 of the rolling material 3 and the speed v2 of the product 4 after rolling, in the state where the peripheral speed n1 of the roll 1 is matched to the speed v2 of the product 4. If the peripheral speed n2 of the roll 2 is changed from the speed v1 to V2, the curve as shown in the figure is obtainable between the rolling load P and n2/n1. Namely, if there is made n2/n1=0 when n2=v1 and n2/n1=1 when n2=v2 with the peripheral speed n1 being constant, then the rolling load P decreases when n2/n1 is changed from 1 down to 0. According to this method, the number of rolls held and the times of roll changing may be considerably reduced.
