Filed: 2022-01-28
Abstract: To prevent curvature at the time when dissimilar metal joining materials are rolled, by identifying the relationship of mechanical properties of metal plates arranged on both sides and the metal plate arranged between them.SOLUTION: In a method for longitudinally rolling a dissimilar metal joining material by arranging and joining two types of metal plates in a width direction, first metal plates 10 with an elongation ratio during rolling being relatively large are arranged at both sides, and a second metal plate 20 with the elongation ratio being relatively small is arranged between them, and then the joining is performed. When the dissimilar metal joining materials are rolled longitudinally, the first metal plates 10 of both sides extending relatively large are rolled while giving tensile tension from both sides in the longitudinal direction to the second metal plate 20 arranged between them. Accordingly, the curvature at the time when the dissimilar metal joining materials are rolled is prevented effectively. The process control being more severe and complicated than before is unnecessary, and thereby it can easily be implemented industrially.SELECTED DRAWING: Figure 3
