摘要
One embodiment of the present invention in weight percent, C: 0.0005 to 0.0060%, Si: 2.6 to 3.8%, Mn: 0.05 to 2.0%, Al: 0.05 to 2.0%, Sn: 0.005 to 0.20%, P: 0.002 to 0.30%, S: 0.0002~0.005%, Ti: 0.0002~0.01%, Nb: 0.0002~0.01%, V: 0.0002~0.01%, N: 0.0005~0.006%, including balance Fe and other unavoidable impurities, It provides a non-oriented hot-rolled electrical steel sheet that satisfies 1 to 5 and has a low iron loss and excellent surface quality with an unrecrystallized structure of 30 to 80 area%. [Relationship 1] 3.5 ≤ [Si+Al+(Mn+Sn)/2+5P] ≤ 6.0 [Relationship 2] 1.0 ≤ [(Ti/48+Nb/93+V/51)(C/12+N/14)]×10
