| description | To provide a magnetic steel sheet laminate which is reduced in core loss furthermore and increased in strength.SOLUTION: A method for manufacturing a magnetic steel sheet laminate 71 includes: manufacturing an initial magnetic steel sheet laminate from a magnetic steel sheet strip by means of helical winding: coating steel sheet layers 510, 520, 530 of the initial magnetic steel sheet laminate with coatings 61, 62, the coating containing aluminum and/or silicon in a weight percentage of at least 20 wt.%; and subjecting the coated initial magnetic steel sheet laminate 50 to heat treatment to obtain the magnetic steel sheet laminate 71. When heat treatment is performed until uniform distribution of silicon is achieved in the magnetic steel sheet laminate 71, a magnetic steel sheet laminate 71 having a silicon content of at least 6.5 wt.% can be obtained. If heat treatment is performed until a gradient of silicon content is present in the magnetic steel sheet laminate, a magnetic steel sheet laminate having a silicon content of greater than 4 wt.% and less than 6.5 wt.% can be obtained.SELECTED DRAWING: Figure 3
【課題】磁心損失をさらに減少させ、強度が増大した電磁鋼板積層体を提供する。【解決手段】電磁鋼板積層体７１の製造方法は、ヘリカル巻きによって電磁鋼板ストリップから出発電磁鋼板積層体を製造することと、出発電磁鋼板積層体の鋼板層５１０、５２０、５３０を、少なくとも２０重量％のアルミニウムおよび／またはケイ素を含有するコーティング６１、６２でコーティングすることと、電磁鋼板積層体７１を得るために、コーティングされた出発電磁鋼板積層体５０を熱処理することとを含む。電磁鋼板積層体７１内でケイ素の均一な分布が達成されるまで熱処理を実施すると、ケイ素含有量が少なくとも６．５重量％である電磁鋼板積層体７１を得ることができる。電磁鋼板積層体内でケイ素含有量の勾配が存在するまで熱処理を実施すると、ケイ素含有量が４重量％超かつ６．５重量％未満の電磁鋼板積層体を得ることができる。【選択図】図３ |
