Abstract

PURPOSE: To enable the chock of the rolling mill to arbitrarily adjust the skew angle without the use of a high-accurate position detector, by attaching a tachometer to the driving device for operating the positioning nut for adjusting the skew angle of the work roll, at continuously controlling the skew angle during the rolling work.
CONSTITUTION: A couple of cavities 6, 6, are bored in parallel with the center of axis of the roll 3 in each of side planes 5, 5, on the feed-in side A and the run-out side B of the work roll chock 2; the liner holding rods 71, 72, are respectively fitted into these cavities 6, 6, so as to be slidable. The pressure oil is supplied into the cavity 6 for thrusting the rod 7 at the corresponding liner 8. The fixing pieces 10, 10, are fixed to specified positions in the outer surface of the rods 71, 72, on the run-out side B; and the oil pressure is applied to the rods 71, 72, on the feed-in side A in order to press the chock 2 against the pieces 10, 10; thereby, the roll 3 is fixed to an unskewed normal condition. Besides, external gears 14, 15, are respectively arranged for the positioning nuts 91, 92, attached to the rods 71, 72; the number of teeth of these gears 14, 15, is determined from the formula, and a tachometer is attached to the driving unit for operating the nuts 91, 92.
