摘要： PURPOSE:To miniaturize a joining device and to shorten joining time by forming the rear end part of a preceding rolled stock and the tip part of the following rolled stock into an approximately rectangular projecting and recessed parts which are mutually fitted in and executing finish rolling after these projecting and recessed parts are mutually combined in the same plane as the rolling line. CONSTITUTION:The rear end part of the preceding rolled stock 1 after rough rolling and the tip part of the following rolled stock 6 are joined and finish rolling is continuously executed. The rear end part of the preceding rolled stock is cut at a cutting line 3 avoiding the crop part 2. The shape of the rear end part after cutting is made into a shape that the recessed part 4 and project part 5 are continued. Also the tip part of the following rolled stock is cut into the similar shape and formed into approximately rectangular projecting and recessed parts 4, 5 which are mutually fitted in. After these projecting and recessed parts are mutually combined in the same plane as the rolling line, they are joined by executing finish rolling. In this way, the miniaturization of the joining device and shortening of joining time can be realized.

摘要： PURPOSE:To execute the grinding work of stability by installing the rotary shaft of a grinder shifting from the rotary shaft of the roll by the amt. of offset and setting the relation between the amt. of offset and the dimension of the grinder in a specified relation at the time of grinding the roll without driving the grinder forcibly. CONSTITUTION:In a frame which is able to move back and forth along the axial line OR of a work roll 1 plural grinder holders 6 pushing the grinder 3 set at its end part on the roll surface are arranged in the axial direction of the roll. The above grinder is set in the above holder with its rotary shaft inclined to the roll axial direction against the perpendicular line on the roll surface and with its rotary shaft 4 shifted by the amt. of the offset H from the rotary shaft line of the above roll. On the method of grinding the above roll without forcedly driving the grinder, the relation of the amt. of offset H and dimensions of grinder D, d is set within the range of equation I and equation II, and therefore the grinding work of stability is executed without generating cracking of the grindstone, the bad vibration and the baking, etc.

摘要： PURPOSE:To permit the follow-up shift of a spindle to a work roll and to simplify the construction of a spindle device by executing a roll shift while the spindle is held pressed to the work roll by a spindle shift cylinder. CONSTITUTION:The spindle shift cylinder 9 is driven by a hydraulic device to hold the spindle 4 pressed to the work roll 1 via a connecting coupling 14. The work roll 1 is shifted leftward by a shift block 7, a connecting plate 3a and a chock 3 and the spindle 4 is shifted by the pressing force of the cylinder 9 in follow up to the work roll 1 when a roll shift cylinder 8 is driven. The spindle 4 is slightly moved to a driving side D by the cylinder 9 to eliminate the axial load acting on the slipper 14a and slipper pin 14b of the coupling 14 when the shift of the roll 1 is completed. The axial movement of the spindle 4 is further fixed by blocking the oil pressure of the cylinder 9.

摘要： PURPOSE:To permit the selective use of a shift roll and conventional roll and the reduction of a product cost by providing a work side bender block slidably with a housing. CONSTITUTION:The bender blocks 34, 34' are incorporated into the housings 31, 31' on the driving side D and work side W of a rolling mill and the bender block 35 is fixed to the housing 31. On the other hand, the bender block 37 is slidably fixed to the housing 31' and a liquid pressure cylinder 38 is disposed. A cylinder 38 is operated to move a cylinder block 37 and the block is pressed to the housing 31' by means of bolts 39 in the stage of using a shift roll 32. A projecting part 43 of a roll chock 42' is clamped by the bender block 37 in the stage of using the conventional roll 41. Since the selective use of the shift roll 32 and the conventional roll 42 is made possible by the above- mentioned method, the roll consumption is reduced. The cost is thus reduced.

摘要： PURPOSE:To permit reduction of an initial cost, etc., by using a magnetic material to form a piston rod of a roll shift cylinder, disposing annular nonmagnetic materials to the outside circumference thereof and detecting the roll shift position via a change in the magnetic resistance. CONSTITUTION:The piston rod 6 consisting of the magnetic material is fixed to a piston 25 of the roll shift piston rod 5 and the annular nonmagnetic materials 24 are mounted at an equal pitch on the outside circumferential surface thereof nearly over the entire length thereof. On the other hand, a non- contact type position detector 22 consisting of an annular electromagnetic coil is disposed to the inside circumferential part of a cylinder cover 21. A change in the induced voltage of a coil of a head 23 is detected via the change in the magnetic resistance if the coil is excited to actuate the cylinder 5. The roll shift position is then exactly measured. Since the construction of the detector is simple, the initial and maintenance costs of the device are reduced and the accuracy of the shift position detection is improved.

摘要： PURPOSE:To flatly roll the rolling materials of various kinds of sizes and materials without requiring roll spares of multiple kinds of crown amounts by loosely fitting offcentered sleeves to both side parts and central parts of the backup rolls of the 4-stage rolling mill and providing rotating devices for controlling of the rates of offcenter to the roll bodies. CONSTITUTION:At the time of rolling a plate-form rolling material 1 by a work roll 2, sleeves 7, 8 are rotatably loosely fitted to the outside circumferences of both side parts and central part of upper and lower backup rolls 5. The central sleeves 8 are mounted with offcentering by e with respect to the revolving center of the backup rolls 5. When the rolls 5 are revolved by driving fine adjustment devices 16, the roll bodies 5 revolve about the center A of the roll bearings 12 and the center B of the central sleeves 8 deviate by e1. When rolling is done in this state and if the maximum deflection of the rolls 5 is equal to e1, the outside surfaces of the contact of the sleeves 7, 8 with the work rolls 2 become linerar irrespective of the deflections of the rolls 5 and the rolling material 1 is flatly rolled.
