Zusammenfassung:The invention belongs to the technical field of strip steel production, and particularly relates to a strip steel hot rolling control method. The method comprises the steps of providing a plate blank;and controlling tapping operation of the provided plate blank in a control mode that the temperature of the head of the plate blank is higher than the temperature of the middle and the temperature ofthe tail of the plate blank. According to the strip steel hot rolling control method, the heating temperature of the head of the plate blank can be increased, the temperature of the head of the plateblank can be higher than the temperature of the middle and the temperature of the tail of the plate blank, the difference between the temperature of the head of the plate blank and the temperatures of the middle and the tail of the plate blank in the rolling process is reduced, and therefore the FDT hit rate of the head of strip steel can be guaranteed, the situation that the steel is stacked onthe head due to the fact tha
