ABSTRACT:
A grain-oriented silicon steel sheet having high magnetic induction and low iron loss can be produced by controlling properly the particle size of carbide precipitated in the crystal grains of the steel sheet before final cold rolling. Further, the magnetic properties can be more improved by adjusting the C content in a starting silicon steel depending upon the Si content in the steel and removing a proper amount of C from the steel during the course after completion of hot rolling and before final cold rolling, in addition to the proper control of the particle size of carbide precipitated in the crystal grains of the steel sheet before final cold rolling.
