CAST SLAB OF NON-ORIENTED MAGNETIC STEEL AND METHOD FOR PRODUCING THE SAME
Document Type and Number:
WIPO Patent Application WO/2010/010801
Kind Code:
A1
Abstract:
There is prepared a molten steel containing, in mass%, not less than 0.1% but not more than 7.0% of Si, not less than 0.1% of Mn, not less than 0.2% but not more than 5.0% of Al, not less than 0.1% but not more than 10% of Cr and the like, and the balance of Fe and unavoidable impurities. A REM is added in the molten steel in an amount of not less than 0.0005% but not more than 0.03%. The molten steel into which the REM is added is then casted. As a result, there is produced a cast slab of a non-oriented magnetic steel.
