る（特開昭５８−１５５９４６号参照）。<Prior art and its problems> Conventionally, when manufacturing vibration-damping steel plates, etc., which are one type of composite steel plate, in which polymer film is laminated, for example, thermoplastic A resin film is sandwiched and preheated to lower the Young's modulus of the film to soften it, defoamed with a pressure roll outside the furnace, then heated again with a heating device, and then heated with a hot roll. A manufacturing method and manufacturing apparatus for melt-press bonding have been proposed (see Japanese Patent Laid-Open No. 155946/1983).

しやすい。(2) Once the laminate is pulled out of the furnace and pressed together, it is rapidly heated again to the melting point of the polymer film, so the outer surface of the steel plate is inevitably heated rapidly to a temperature considerably higher than the melting point of the polymer film. Since rapid heating is performed in a short period of time, temper color is likely to occur on the surface of the steel sheet.
