Abstract

PURPOSE: To prevent the camber of sheet and to manufacture the product of good quality, by arranging in each stand the high speed rolls in zigzag up and down alternately.
CONSTITUTION: In the first stand S1, the lower work roll 9 is made faster than the upper work roll 8; in the second stand S2, the upper work roll 10 is made faster than the lower work roll 11; and in the following stands, the faster work rolls 9, 10, are alternately arranged in zigzag. The high speed regulator 12 drives the motor 12c through the speed controller 12a and the speed meter 12b, and controls the circumferential speed of the upper work roll 8 to the settled speed. Similarly, the circumferential speed regulators 14, 15, respectively controls the circumferential speed of the lower work roll 9 to the settled speed faster than the circumferential speed of the upper work roll 8, and the circumferential speed of the upper work roll 10 to the settled speed faster than the circumferential speed of the lower work roll 11. The correction operator 16 for the thickness of sheet converts the deviation of thickness detected by the thickness gauge 6 into the rolling load; and when a fluctuation is caused in the thickness, the operator 16 corrects the settled load of the screw down device 18 of each stand.
