PROBLEM TO BE SOLVED: To obtain a hot rolled electric steel sheet having a texture which is highly accumulated in the azimuth of 110} <001> in the stage of rolling. SOLUTION: This electric steel sheet consists of composition containing <=0.005 wt.% C and <=7 wt.% Si, has the texture whose accumulating strength in the azimuth of 110} <001> over the entire of thickness including the centeral part in thickness is >=10 times that of a random structure and whose thickness is <=1.5 mm. In the manufacturing method of this electric steel sheet, after a steel slab containing <=0.005 wt.% C and <=7 wt.% Si is hot rough-rolled, the finish rolling is executed to <=1.5 mm thick under the conditions that the draft (one pass) is >=30% and rolling completing temp. is 600-800 deg.C. |
