ABSTRACT:
A rapidly-solidified non-oriented electrical steel sheet having high magnetic flux density and low core loss is provided.The method of producing the non-oriented electrical steel sheet excellent in magnetic properties comprises casting a steel strip by using a traveling cooling roll surface(s) to solidify a steel melt of a prescribed chemical composition, which melt contains one or both of REM and Ca at a total content of 0.0020 to 0.01% and is cast in an atmosphere of Ar, He or a mixture thereof.
