<P>PROBLEM TO BE SOLVED: To solve the problem that core-loss reduction effect obtained by giving a tension is not sufficiently exhibited because the tension in the right angle direction to a rolling direction of a grain-oriented magnetic steel makes elastic extension of the steel in the rolling direction small and lowers the substantial tension in the rolling direction. <P>SOLUTION: In the grain-oriented magnetic steel sheet, after forming a tension-coating, the extension in the right angle direction to the rolling having ≤3.0%, is given in the rolling direction at the right angle to the rolling. <P>COPYRIGHT: (C)2010,JPO&INPIT |
