Abstract

PURPOSE:To adjust accurately and separately with a simple device in a roll gap adjustment, by interlocking upper and lower hydraulic rolling-reduction cylinders into a pair, and actuating them by a separately installed synchronizing cylinder, and detecting roll positions too. CONSTITUTION:A flow regulating valve 47 is actuated by a flow-rate setting signal 52 to move a piston 45a of a synchronizing cylinder 45, and hydraulically interlocked hydraulic rolling-reduction cylinders 40, 41 are actuated to adjust the roll gap of rolls. The position of the piston 45a is detected by a position detector 49 to transmit it to a controlling arithmetic device 51. The device 51 adjusts finely the valve 47 so that the specified roll position is obtained, to adjust the positions of the cylinders 40, 41 through the synchronizing cylinder 45. This device is of low price, and is capable of not only adjusting the left and right rolls simultaneously or separately but being installed at the separated place where no vibration occurs, accordingly the adjustment is accurately performed and the working efficiency of the line is improved.

In addition, in order to precisely control the position of each oil cylinder, the position of each hydraulic cylinder is individually detected and the hydraulic pressure is controlled independently by a hydraulic control device that responds to each cylinder independently. Since we have been performing 'ζ position control, we have had a multiple control device configuration, and the frequency of troubles has been caused by humans.Furthermore, two IJ-rules are installed in the normal rolling 11i'1'.
The opening must be controlled symmetrically from the center of the rolling mill.・When initializing the opening of the CI-ru after changing the force and rolls, it is necessary to adjust the opening of the CI-ru on one side using a hydraulic pressure cylinder. The hydraulic downstream cylinder is required to have both the function of symmetrically stroking the two rolls with good accumulation and the function of arbitrarily stroking the rolls on one side.
