PRODUCTION OF DAMPING LAMINATED STEEL SHEET

摘要

PROBLEM TO BE SOLVED: To easily produce a damping laminated steel sheet equipped with a foam layer. SOLUTION: A method for producing a damping laminated steel sheet 1 equipped with a foam layer is equipped with a lamination process bonding a granular or powdery foamable material 12 to the surface of a steel sheet 11 in a laminar state to form a laminated sheet 13 and a foaming process heating the laminated sheet 13 to foam and expand the laminar foamable material 12 to form the foam layer 2 and bonding the foamed layer 2 to the surface of the steel sheet 11 at the same time.
