<P>PROBLEM TO BE SOLVED: To provide a method for producing a non-oriented magnetic steel sheet which can obtain a high magnetic flux density at low cost. <P>SOLUTION: In the production of the non-oriented magnetic steel sheet satisfying 0.1-2.0% Si, ≤1.0% Al and 0.1-2.0% Si+2Al and containing ≤0.004% C, it is decided that a slab heating temperature ST in a hot-rolling is 700-1,150°C, a finish-rolling starting temperature FOT is 650-850°C and a finish hot-rolling completing temperature FT is 550-800°C. <P>COPYRIGHT: (C)2011,JPO&INPIT |
