MULTI-LAYERED ELECTRIC STEEL SHEET MANUFACTURING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a multi-layered electric steel sheet of high quality so that all laminated steel sheets are subjected to desired decarburization-annealing even when three or more steel sheets are laminated in a multi-layered electric steel sheet manufacturing method. SOLUTION: In the multi-layered electric steel sheet manufacturing method comprising at least a step of performing cold rolling to the target thickness after two or more electric steel sheets 30 overlap by using adhesive 31, each steel sheet is subjected to decarburization-annealing processing as a preceding step of a step of laminating two or more steel sheets 30.
