PURPOSE:To correct the deflection in the transverse direction generated during rolling and to obtain a flate composite material by superposing plural plate materials and joining the materials by rolling to form a composite material then subjecting the composite material to rolling to curve the material in the transverse direction. CONSTITUTION:Prescribed metallic belt-like plate materials 1, 2 are combined and superposed then the superposed materials are press-welded and joined by hot or cold rolling to form a composite material 3. The composite material is subjected to a reduction of area to a prescribed thickness by cold or hot rolling according to need. The composite material 3 is then passed between a roll having a projecting surface and a roll having a recessed surface to correct the transverse deflection of the material 3 and to flatten the material. If there is a need for curving the composite material in the transverse direction according to applications, the transversely flat material 3 is rolled to curve transversely. Production of bimetals is made possible by utilizing the above-described working. |
