Embodiments of the invention disclose an automatic leveler shutdown control method. The method includes: determining a target operating state of a leveler; determining a real-time operating state of the leveler which enters in the operating state; when the real-time operating state of the leveler reaches the target operating state, sending a shutdown control command to the leveler. Therefore, the leveler can automatically shut down when autonomously determining that a leveled coil passing slitting shears reaches the specified length of a finished coil; the automation level of the simple production mode is increased and further popularization and application is facilitated; the embodiments further disclose an automatic leveler shutdown control device.
