description The invention provides a production method for improving the rolling efficiency of a ferrite area, and relates to the technical field of hot rolling processes, the production method comprises the following steps: rolling by adopting low-temperature heating, controlling the tapping temperature to be 950-1050 DEG C, and controlling the in-furnace time to be more than 120 minutes; a 3 + 3 rolling mode is adopted for rough rolling, three passes of an R1 rough rolling mill are adopted, and three passes of an R2 rough rolling mill are adopted; all-pass descaling is adopted by the roughing mills R1 and R2; a first intermediate billet cooling device is arranged at an inlet of the R1 rolling mill; a second intermediate billet cooling device is arranged at an outlet of the R1 rolling mill; a third intermediate billet cooling device is arranged at an inlet of the R2 rolling mill; and a fourth intermediate billet cooling device is arranged at an outlet of the R2 rolling mill. According to the production method for improv
