NON-ORIENTED ELECTRICAL STEEL SHEET WITH LOW CORE LOSS |
| 摘要 |
<P>PROBLEM TO BE SOLVED: To provide a non-oriented electrical steel sheet which has particularly low core loss and high magnetic flux density and has excellent magnetic properties which has not existed before and is used as an iron core material for electrical equipment and also to provide its manufacturing method. <P>SOLUTION: Proper amounts of REM are added to steel and also Sn is added to improve the texture of the steel sheet. By this method, the non-oriented electrical steel sheet with low core loss can be obtained while avoiding deterioration in magnetic flux density. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
