摘要： PURPOSE:To extract a coil and to supply rapidly a spool, by inserting a new spool into an upper space caused by the descent of a coil extracting device which is actuated immediately after extracting a coil from a coiling axis. CONSTITUTION:A titled device is constituted by providing, as accessories, a spool supplying device 19, a coil taking-out device 12, and a controlling device in addition to a coiling drum 17 placed at the outlet side of a rolling mill 16. The device 19 has a horizontally moving part which moves the device 19 in the axial direction of the drum 17 and in the direction perpendicular to said direction. Further, the device 12 has a driving part which actuates the descending motion of the device 12 when it moves to the position of coil extraction along the axial direction of the drum 17. Then the initial movement of the device 19 to the axial center and the descending movement of the device 12 are combined without idle time. Thus the extraction of a coil and the supplying of a spool 15 are rapidly performed by the titled device.

摘要： PROBLEM TO BE SOLVED: To prevent the occurrence of scratches on the surface of a rolling material and a trouble of responsivity in cold rolling, to properly respond to a variation of a thermal crown that momentarily varies while rolling, and to prevent the deterioration of the whole shape of a plate. SOLUTION: In a six-stage rolling mill, a local pit-shaped crown 2a having a club shape towards its tip is formed at one end of each working roll 2 that comprises a shifting unit, the working rolls 2 are so disposed as to be symmetric with respect to a top-and-bottom point. A decrease bender 10b that acts to narrow a gap between the working rolls is mounted as a first shape-controlling means, and the local pit-shaped crown 2a is used together with the roll bender 10b for controlling the thermal crown. In order to compensate a variation of a body crown caused by use of the roll bender, an increase bending unit 11a that controls a deflection of an intermediate roll 3 is mounted as a second shape-controlling means capable of controlling a shape of the center part of the rolling material at least to the pit-shaped crown side.

摘要： PROBLEM TO BE SOLVED: To improve the quality in shape even when a rolled stock has asymmetrical thickness distribution with respect to the center of the rolled stock by arranging rolls so that the point of action of the bending force of a roll bending device is asymmetrical with respect to the center of the rolled stock and controlling screw-down location so that the total sum of the moment of distributed rolling load which acts on the roll to the center of the rolled stock becomes approximately zero. SOLUTION: It is assumed that the right and left work roll bending forces are equal, intermediate roll bending forces Fi are also equally controlled and the fore Fi is expressed by Fi=FbL+FbR (where, FbL=FbR). Detected supporting loads FbL, FbR are calculated and averaged and measured δFbL of an unbalance supporting load which acts on at present is outputted. On the other hand, calculated δFb is determined from the deviation between the measured amount (s) of shift and the quantities of the state of the force Fi with a deviation unbalance supporting load computing element, and added to the reference δFb and outputted. The difference between this target δFb and the above force FbL is calculated, is inputted into the position commanding device and the position command values δCbL, δCbR to the right and left screw-down cylinders are outputted.

摘要： PURPOSE:To protect the winder and coil from being damaged by making the cradle contact slightly with the coil in a mechanism wherein the cylinder to lift the winding coil cradle is actuated by hydraulic pressure being controlled and reduced thru relief valve. CONSTITUTION:Winding operation at the coil 13 is carried out along the sequence as below: (a) by the operation of valve 18, wedge piece 9 is moved to the left via cylinder 11, which enlarges the diameter of the drum 8 being consisted of a plurality of a plurality of segments, (b) at the same time, by the operation of the valve 37, pressure at the reducing valve 30 is made equal with the value set at the relief valve 3l via the bypass pipe 33, then, (c) the winding of the coil 13 is started. Before the winding is finished, by the operation of the valve 28, hydraulic pressure being reduced at the reduction valve 30 is supplied to the down chamber C of the cylinder 21 which lifts the cradle 20 upward and after making it contact with the coil 13 slightly, supply of hydraulic pressure is suspended by operating the valve 28. After the winding is completed, diameter of the drum 8 is shrunk thru the cylinder 11 by operating the valve 18, valve 37 is switched, setting the pressure at the chamber C of the cylinder 21 at the value as set at the relief valve 32, and the coil is drawn out while the coil is being supported by the cradle.
