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.

摘要： PURPOSE:To obtain the titled welder whose upper shearing blade exhibits its function in only one-way motion, by incorporating shearing unit using a rotatable round blade as an upper shearing blade, and using a straight blade that servs both as an lower electrode, as a lower shearing blade. CONSTITUTION:The flash butt welder consisting of fixed table 2 and traveling table 3 centers the tail end part of leading steel belt 1 on the head part of following steel belt 1-2 and clamps them by lower shearing blades 6 and 6-2 serving both as lower electrodes and upper electrodes 4 and 4-2. Upper shearing blades 5 and 5-2 are both rotatable round blades, which are supported on rails 21 and 21-2 via saddles 7 and 7-2 and movable along the weld line. In said constitution, lower blades 6 and 6-2 are straight ones, so that curvature 30 seldom occurs. Additionally, the conventional titled welder needs to perform going and returning motion for every welding, but this welder can exhibit the function of upper shearing round blade in only one-way motion.

摘要： PURPOSE:To perform a flash welding without scattering the spatter outside, by conducting the gas including the spatter to the spatter isolating means via the pipe line from the chamber which encloses the welding part of the object to be welded. CONSTITUTION:When a fan 8 is rotated while performing the welding, the air flows in through the opening part at one end of the chamber 18 and then goes into the suction hood 5 along with the spatter (a). The air flow speed is uniformly adjusted by the adjustment damper 13 between the upper and lower chambers partitioned by the strip 2. The air flowed into the hood 5 and including the spatter (a) enters the separator 7 via the transport pipe 6. The separator 7 reduces the flow speed to separate the coarse grain spatter 10, and the separated spatter 10 is discharged into the backet 11 by the operation of the double open/close-type cover. Then the fine spatter is separated through the bag filter 9 to be stored in the dust box 12.

摘要： PURPOSE:To effectuate less deformed shear over all the width of the strip in such a way that depression of the strip is eliminated by offsetting upper and lower rotary shear blades in the directions of shearing lines, and the strip is clamped close by the shear blades. CONSTITUTION:By properly selecting offset extent S of upper shear blade 4, lower shear blade 5 to a strip 1 of thick plate, upper surface and lower surface of the strip 1 begin to come into contact with upper and lower shear blades 4, 5 in the shearing direction almost at the same time, the strip 1 undergo all but no depression in the vertical direction. By this reason, the strip 1 can be clamped close by the shear blades 4, 5 with use of upper and lower clamps 2, 3, by which less deformed shear can be obtained over all the width of the strip 1.

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.
