摘要： PROBLEM TO BE SOLVED: To provide a process for manufacturing a grain-oriented magnetic steel sheet having an excellent surface quality and a high magnetic flux density. SOLUTION: A Bi-containing material is introduced into molten steel which contains 0.01-0.15% C, 2.5-5.5% Si and 0.03-3.0% Mn and has a flow rate of ≥70 g/(scm 2 ) to obtain a slab containing 0.002-0.08% Bi through continuous casting. The slab is subjected to rough rolling and subsequently to finish rolling by a tandem mill at 800-1,150°C wherein the cumulative rolling reduction in the first four stages comprising first to fourth stands is 70-95%. Next, the slab is successively subjected to cold rolling, primary recrystallization annealing and final finish rolling to obtain the grain-oriented magnetic steel sheet having an excellent surface quality and a high magnetic flux density.
