摘要： PURPOSE:To obtain good steel strip products with eliminating the unstabilized straightening part generated on a strip steel at the operation starting and finishing times by giving to a leveller roll the specified state of rolling reduction at the operation starting and finishing times. CONSTITUTION:The operation is executed by arranging a deflector roll 3 on the outlet side of leveller roll group 2, speed detector 4, the intermesh setters 9, 10, 11, 12 to perform position setting and the arithmetic unit 13 to set up the intermesh of each leveller roll 5, 6, 7, 8 according to the movement of the strip steel with operating the strip steels position by speed detecting signal. At the operation starting time of the tension leveller, the rolling reduction is applied by bringing into contact with the strip steel the rolls in order from the leveller roll 5 of the inlet side by setting to the passing through the prescribed position of the strip steel and at the completion time the rolls are released in order from the strip steel from the leveller roller of the inlet side by setting to the passing through the prescribed position of the strip steel. The camber and shape change at the starting and finishing times of tension levelling are thus prevented.

摘要： PURPOSE:To prevent the camber variation of a strip by adjusting the intermesh of a leveler roll prior to the passing of a leveling unnecessary part, thereafter, by shifting the strip tension to a lower tension, further by performing the reverse operation after its passing. CONSTITUTION:The inlet side and outlet side bridle rolls 3, 4 are arranged for a leveler roll group 2 and on the bridle roll 4 a tracking pulse counter 5 of the strip, the rolling reduction setters 10, 11, 12, 13 performing the rolling reduction and release of leveler rolls 6, 7, 8, 9 and a load cell 14 are respectively set up. The intermesh adjustment and the high and low switching of the strip tension are performed in case of the passing of the leveling unnecessary part, by tracking the leveling unnecessary position via the signal of the pulse counter 5. In this way, the deflection variation of the strip before and behind the leveling unnecessary part can be prevented.

摘要： PURPOSE:To perform a flash welding without scattering the spatter outside, by giving the rotary drive to each sealing plate provided to the conductor or the member connected to the mobile and fixed upper and lower electrodes each in order to cover the welding part. CONSTITUTION:The cylinders 18 and 19 are actuated to rotate the sealing plates 1 and 3 which cover the upper parts of the upper electrode 8 of the mobile side and the upper electrode 8' of the fixed side respectively. And the plate 1 is set to ride on the insulated plate 5 on the plate 3 while performing the welding to prevent the outside scattering of the spatter at the upper part of the strip 25. On the other hand, the sealing plate 10 is rotated by the cylinder 20 to secure a contact to the insulated plate 12 of the lower electrode stand of the mobile side to prevent the outside scattering of the spatter at the lower part of the lower electrodes 9 and 9'. When no welding is given to the strip 25, the plates 1, 3 and 10 are set under the state as shown by the 1-dot chain lines. Thus the passing is made possible for the rotary shears which cuts the strip before welding or the trimmer which eliminates the fins.

摘要： PURPOSE:To make exchanging of buckets easier and enable the volume of buckets to be effectively utilized by holding the scraps cut before welding of the opposing works with the damper mechanism between the shearing device and buckets and controlling the falling direction of scraps. CONSTITUTION:At the cutting of the works 26 on the stationary table 2 side with a cutting device 15, the control body 19 of a damper mechanism 25 is operated at the specified angle with the fulcrum axis 21 as a center by a fluid cylinder 22a. The other control body 20 is also operated at the specified angle with the fulcrum axis 21 as a center by a cylinder 22b. Next, when the end parts of the works 26 are cut with the device 15, the scraps 26a fall into the specified position in a bucket 18 by way of the control body 19. The works 27 on the movable table 3 side are also treated in the similar manner. At the exchanging of the bucket 18, the control bodies 19, 20 are made level and the scraps 26a, 17 are temporarily held on these. At the time when the exchanged bucket is inserted, both control bodies are lowered and the scraps are subsequently superposed in the bucket 18.
