GRAIN-ORIENTED ELECTRICAL STEEL SHEET WITH EXCELLENT FILM CHARACTERISTICS AND MAGNETIC PROPERTY, AND ITS MANUFACTURING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a grain-oriented electrical steel sheet in which film adhesion is improved and application of tension by glass film to steel sheet can be effectively exhibited and which has low core loss value and excellent film characteristics and magnetic property, and its manufacturing method. SOLUTION: In the grain-oriented electrical steel sheet with glass film, the proportion of grains having <=10 deg. deviation angle from the 110} <001> crystal orientation is <=0.5, in the orientation distribution of the fine grains of the steel sheet in the mixed region of the anneal film and the steel sheet.
