摘要：
A method of producing non-oriented magnetic steel plate having high magnetic flux density in a low magnetic field and uniform magnetic properties through the thickness direction, comprising selection of a heating temperature and finish rolling temperature to coarsen the size of the austenite grains and prevent refinement of the grain size in the rolling process, and annealing the steel after it has been rolled.
