摘要： According to the invention, the rear end of a preceding metal piece and a front end of a succeeding metal piece are heated, pressed and joined prior to the finishing hot rolling. An alternating magnetic field running through the metal pieces in the thickness direction thereof is generated in an end region on opposed faces of the respective metal pieces to perform heating. Another alternating magnetic field whose direction is reverse with respect to that of the former alternating magnetic field is partially generated in the end region on the opposed faces of the metal pieces and in either a region where the metal pieces exist or a region outside width ends of the metal pieces. This assures a uniform heating of the end region on the opposed faces of the metal pieces over their full width to reliably join the both metal pieces to each other.

摘要： The invention comprises a continuous hot rolling method in which a rear end portion of a preceding metal block and a fore end portion of a succeeding metal block are cut and the metal blocks are joined to each other by heating and pressing followed by a finish rolling. A region of each metal block is restrained from a clamping position to the end portion thereof in order to prevent a change in level of the metal blocks in heating and pressing the piece. The end portions of the metal blocks can be thus prevented from deformation.

摘要： An apparatus for joining metal pieces using induction heating. Preceding and succeeding metal pieces are followed by a carriage which carries an inductor. The inductor has the ability to move in the longitudinal direction of the metal pieces relative to the carriage to allow the inductor to move more or less upon the preceding or succeeding metal pieces to increase or decrease the induction heating effect, thereby taking into account any thickness variation of the metal pieces and yet still heating them evenly with regard to each other, prior to their being pressed against each other for joining before hot finishing rolling.

摘要： Method and apparatus for joining metal pieces using induction heating. Metal pieces to be joined are placed end-to-end with a gap between them and induction heated in the thickness portion. To maximize speed and even heating edge-to-edge of the ends, members of a magnetic substance are provided in a gap between the inductor and the piece to be heated, thereby enhancing local heating effect by increasing magnetic flux density. Once heated, the ends are pressed together end-to-end for joining.

摘要： The invention provides a method for improving the luster of a metal sheet surface without deteriorating the productivity and also in reducing the difference in glossiness between the upper and lower surfaces of the metal sheet at the time of cold-rolling. By making the velocity, after rolling of the metal sheet, equal to or larger than the rotational circumferential velocity of the work rolls, and by rolling the metal sheet with upper and lower work rolls crossed with each other in such manner that an angle of slip scratches left on the metal sheet surfaces becomes 5 degrees or larger and shear deformation in the widthwise direction can be effectively given to the metal sheet just before rolling, thereby improving the surface luster of the metal sheet. In addition, in the case where luster of the metal sheet surface is improved by changing the cross angle between the upper and lower crossing work rolls, the sheet configuration is corrected by a configuration control actuator, depending upon the sheet configuration of the metal sheet after the cross angle is changed. Furthermore, the difference in glossiness between the upper and lower surfaces of the metal sheet is reduced by selecting the cross angles formed by the upper and lower crossing work rolls with respect to the direction at right angles to the rolling direction and also employing rolls having different surface roughness as the upper and lower work rolls.
