Title:
GRAIN ORIENTED ELECTROMAGNETIC STEEL PLATE WITH LOW IRON LOSS
Document Type and Number:
Japanese Patent JP3333798
Kind Code:
B2
Abstract:
PURPOSE: To obtain a grain oriented electromagnetic steel plate which facilitates the suppression of the unevenness of a magnetic flux distribution in the steel plate and the significant reduction of an iron loss.
CONSTITUTION: A silicon containing steel plate which is subjected to a final finishing annealing has a foundation covering film which contains 0.1-0.7g/m2 of Al component and 0.1-0.8g/m2 of Ti component on its surface, has the average aspect ratio of 0.10-0.95 between the rolled direction length and the plate width direction length of a secondary recrystallized grain and, further, has a magnetic flux density B8 is not less than 1.89T at a magnetization force of 800A/m. With this constitution, a grain oriented electromagnetic steel plate with a significantly low iron loss can be obtained.
