Abstract

PURPOSE: To maintain the breadth of slab at constant while the rolling work, and to contrive the improvement of the yield, by constituting the dummy caliber consisting of the roll group whose position is adjustable, instead of the vertical roll provided with the caliber.
CONSTITUTION: The distance between the end faces of the thrust rolls 3 of the broadside rolling mill is set by reducing, etc., the pressure of the balance cylinder 26 with the position adjuster 5, so as to be equal or a little narrower than the breadth of the slab (a) to be rolled. Next, the draft of the backup roll 4 is set so as to make the distance between the lower face of the thrust roll 3 and the upper face of the flange 2 of the vertical roll 1 to be equal to the thickness of the slab (a) to be rolled. Finally, the screw-down of the vertical roll 1 is carried out so as to make the gap of the right and the left vertical rolls 1 to be equal to the breadth of the slab (a) to be rolled. As a result, the caliber size required for the rolling work together with the setting action of the breadth of the slab (a) can be freely obtained, and the fluctuation in the breadth of the final product is made small, and the yield is improved.
