PURPOSE:To heat both end parts of a strip with a little electric power and to improve the strip quality by installing a couple of laterally movable suspended frames from an overbridge type gantry on the pass line between hot finishing rolling mills and installing a couple of induction heaters being vertically movable on the inside face of the frames facing each other. CONSTITUTION:Carriers 2a movable in the width direction on an overbridge type gantry 1a on the pass line between hot finishing rolling mills. Intermediate movable frames 5a and 5b, which are vertically moved by cylinders 12a, 12b and a distance between the frames 5a, 5b is adjusted by a gap setting cylinder, are installed on the inside face of a couple of vertical frames 2b facing each other. The frames 2b are suspended from the carriers 2a. The frames 5a, 5b are provided with heating faces 6c, 6d vertically moved by copying cylinders 9a, 9b. The heating faces 6c, 6d to which a steel strip 22 exists hold a proper gap against the strip 22 by actions of the above cylinders 9a, 9b. End parts of the strip 22 are heated with a temp. rise of the heating faces 6c, 6d by induction heating inductors 15a, 15b. Therefore, the rolling quality of the rolled strip 22 whose both end parts are easily cooled is made to be uniform and good. |
