| description | PROBLEM TO BE SOLVED: To control slab heating temp. to the low one equal to that for common steel and to stably produce a steel sheet uniform in magnetic properties in the longitudinal direction without executing a nitriding stage by controlling the temp. difference between the temp. of the top part in the longitudinal direction and the temp. of the tail part in hot rolling for a slab as to the temp. in which a grain oriented silicon slab having a specified compsn. contg. C, Si, Mn, Al and N is subjected to hot rolling. SOLUTION: As to the production of this steel sheet, a grain oriented silicon slab is heated at |

C, Si, Mn, Al and N is subjected to hot rolling. SOLUTION: As to the production of this steel sheet, a grain oriented silicon slab is heated at <=1280 deg.C, is subjected to hot rolling and finish rolling, is thereafter subjected to hot rolled sheet annealing, is then subjected to cold rolling to form into a cold rolled sheet of final sheet thickness, is subjected to decarburizing annealing in wet hydrogen, is coated with a separation agent for annealing and is subjected to finish annealing. The temp. difference in the hot rolling is controlled to 50 to 150 deg.C.
