<P>PROBLEM TO BE SOLVED: To develop superior magnetic properties after secondary recrystallization by the use of austenite - ferrite transformation, in an oriented electromagnetic steel plate produced by using cold rolling two or more times. <P>SOLUTION: In the production of the oriented electromagnetic steel plate by using as a raw material a steel slab having a predetermined component composition and using cold rolling two or more times, heat processing for between 10 minutes and 480 hours at a temperature range of 500°C to 750°C is performed before one of the cold rollings, except the final cold rolling. <P>COPYRIGHT: (C)2012,JPO&INPIT |
