METHOD FOR PRODUCING HOT-ROLLED STEEL SHEET FOR NON-ORIENTED ELECTROMAGNETIC STEEL SHEET AND METHOD FOR PRODUCING NON-ORIENTED ELECTROMAGNETIC STEEL SHEET

To suppress ridging in a process using thin slabs, ridging being a problem when handling steel containing a large amount of Si, Al, Mn alloying elements. A method of producing a hot-rolled steel sheet for a non-oriented electrical steel sheet includes: a continuous casting process of producing a steel slab by continuous casting, the steel slab having a defined chemical composition and a thickness of 50 mm or more and 200 mm or less; a transfer process of transferring the steel slab to a furnace while maintaining a surface temperature of the steel slab at 800 °C or more; a hold process of holding the steel slab in the furnace under a set of conditions including a hold temperature of 1100 °C or more to 1300 °C or less and a hold time of 60 s or more; and a hot rolling process of subjecting the steel slab to rough rolling, reheating treatment, and finish rolling in sequence to obtain a hot-rolled steel sheet, wherein the hot rolling process is performed under a set of conditions satisfying (1) and (2) below:(1) total rolling reduction of the rough rolling: 80 % or more, and(2) total rolling reduction of the finish rolling: 80 % or more.
