摘要： According to the present invention, a rear end portion of a preceding metal piece and a front end portion of a subsequent metal piece are heated, pressed and joined prior to the finishing hot rolling thereof, by placing the two metal pieces so that the rear end portion of the preceding metal piece and the front end portion of the subsequent metal piece are spaced from and opposed to each other, heating the metal pieces with an alternating field, which passes through the metal pieces in the direction of the thickness thereof, generated in the opposed surface-side end regions of the metal pieces, and partially generating an alternating field, which extends in the direction opposite to the direction in which the previously-mentioned alternating field extends, in the opposed surface-side end regions which agree with either metal piece-existing regions or regions outside of the widthwise ends of the metal pieces, whereby the whole of widthwise parts of the opposed surface-side end regions of the metal pieces are heated uniformly to enable the two metal pieces to be joined reliably.

摘要翻译： 根据本发明，在精加工热轧之前，先前金属片的后端和后面的金属片的前端被加热，压制和接合。 在各金属片的相对面上的端部区域产生贯穿金属片的厚度方向的交变磁场，进行加热。 在金属片的相对面的端部区域和金属片存在的区域或外侧宽度端部的区域中部分地产生相对于前者的交变磁场的方向相反的另一个交变磁场 金属件。 这确保了金属片的相对面上的端部区域在其全宽上的均匀加热，以将两个金属片彼此可靠地接合。
