摘要： PROBLEM TO BE SOLVED: To make it possible to stably heat by interrupting the leakage current of an eddy current to a metallic roll while preventing a spark from generating when heating the strip edge by the induction heating device using a C-type inductor. SOLUTION: The method for absorbing the leakage current of the heating treatment device for the strip edge and absorbing devices 6a and 6b for the leakage current, are provided as follows; that is, in the induction heating device for the strip edge, using the C-type inductor, on metallic rolls 7 supporting the strip on the inlet and outlet of the inductor, a pair of short-circuit rolls 8a and 8b connected through conductors are arranged, and by bringing the short-circuit rolls 8a and 8b into press contact with tip parts on both sides of the strip to be subjected to induction heating, the leakage current of the eddy current being made to flow through the strip, is bypassed.

摘要： PROBLEM TO BE SOLVED: To prevent any wrinkle or swell and defective profile in the plate width direction of a cast slab which are generated by the increase of the surface area of the molten steel between a scum gate and a drum circumferential surface caused by the change of the molten steel level and the increase of the distance between a lower end of the scum gate and the drum circumferential surface caused by the ascent/descent of the scum gate in molding a thin strip cast slab by a twin-drum continuous casting device. SOLUTION: When a drive cylinder 17 is contracted, rollers 16 fitted to the right and left of a gate supporting arm 15 are guided and raised by a guide groove 14, and the gate supporting arm 15 ascends from the position A to the position B. The arc of the guide groove 14 is formed of the radius by adding the distance k between the scum gate 5 and the drum circumferential surface 1a to the radius r of a cooling drum, and the scum gate 5 is raised while maintaining the predetermined distance from the drum circumferential surface 1a. As a result, the surface area of the molten steel between the scum gate and the drum circumferential surface, and the distance between the lower end of the scum gate and the drum circumferential surface are not increased.

摘要： PROBLEM TO BE SOLVED: To provide a control method for the induction heating of the strip edge, by which an unannealed area caused by the interruption of the induction heating, can be sufficiently heated at a time restarting a line, and an unannealed part in the line direction does not occur, for instance, when annealing the strip edge after trimming by a trimmer by heating with the induction heating device, and when the induction heating has been discontinued because of a line stop during the induction heating. SOLUTION: When annealing an edge part by heating up to an annealing temperature by the induction heating over the whole length of the strip, and when the line has been stopped for an undecided time during the induction heating, by compensating a heating quantity required for reaching an annealing temperature to be determined by stop time, plate thickness, etc., by heating during an acceleration just before restarting the line and after restarting the line, the temperature of the strip edge of the unannealed area caused by the interruption of the induction heating, is increased to prevent an unannealed part from generating.

摘要： PROBLEM TO BE SOLVED: To provide a casting drum composed of a Cu-alloy made sleeve and an SUS-made core light in weight, free from the sliding of a fitting part in thermal loading, and long in durable life, in a twin drum type continuous casting drum used for twin drum type continuous casting equipment. SOLUTION: By constituting the SUS made core, which is fitted into a Cu- alloy made sleeve, of ring-shaped cores juxtaposed in the axial direction with a space with one another as a plurality of splitted bodies, the sleeve is movable in the axial direction at the part where the core does not exist, and the relative sliding on the fitting part becomes hard to be caused at the part where the core exists owing to that the length in the axial direction of the fitting part of the sleeve and the core is cut to be short, as a result, enabling the tightening force to be small in fitting of the sleeve and the core, which enables the sleeve to be formed thin.

摘要： PROBLEM TO BE SOLVED: To provide a lubricating device and a lubricating method for a roll type continuous caster, that the lubrication is uniformly applied on the sliding surface to further reduce the wearing. SOLUTION: Sliding members 18, 19 are disposed on the sliding zones 17R, L, in which the inner surface side of the side weir 4 and the end surface sides of the rolls 1 are relatively slid, and the sliding members 18, 19 are formed of a first material and a second material, having different material characteristics, and alternately disposed in the sliding direction of the sliding zones 17R, L so as to have the sliding surface 11 in each of the sliding zones 17R, L. One of the first material and the second material, having mutually different material characteristic, is the lubricant for the other. Powdered powders are transported on the front of high hardness material adjoining in the sliding direction and rollingly shifted or slidingly shifted to lubricate the sliding surfaces on the surface of the high hardness material. Such a lubricating action is repeated in turn in the sliding zones 17R, L, such as the arc orbits and is uniformized over the whole sliding zones 17R, L.

摘要： PURPOSE:To exchange a ladle with one carriage in the stage of casting and to reduce the time for the exchange by disposing a base provided with a lifter for a ladle provided with a support in a trunnion direction and a traveler for the ladle and a stationary stand for holding the empty ladle in a stand-by position to a ladle exchanger for continuous casting. CONSTITUTION:A lifting base 1a of a carriage 1 holds a full ladle 2 and pours the molten steel into a tundish 3 in a casting position A. When the ladle 2 is emptied, the ladle 2 on the base 1a is risen by the lifting device 4 of the carriage 1 and is retreated to the stand-by position of the position B. The carriage 1 arriving at the position B lowers the ladle 2 by the device 4 and leaves the same on a stationary stand 5, then the carriage 1 returns to the position A. When the carriage 1 returns to the position A, the next full ladle 2' carried already by a crane 6 stands by. The ladle 2' is placed on the carriage 1 and the molten steel is poured into the tundish. The crane 6 carries away the empty ladle 2 on the stand 5 in the position B.
