The invention discloses a crystallizer nozzle optimization method based on an optimal F number, and relates to the technical field of steel. The method comprises the following steps: determining the insertion depth, the inclination angle, the side hole width and the side hole height of the crystallizer nozzle according to the F number; according to the requirements for improving the quality and the continuous casting efficiency of a continuous casting slab in actual production, the rule of fluctuation of the liquid level in a slab continuous casting crystallizer is analyzed, and structural parameters of the submersed nozzle are designed and optimized. Meanwhile, when pure steel with the high surface quality requirement is produced, a novel F number calculation method suitable for actual production is found, and slag entrapment of the crystallizer is controlled by controlling the value range of the F number so as to improve the surface quality of a casting blank.
