Method and device for coiling strip steel

The invention relates to the technical field of steel rolling, in particular to a method and a device for coiling strip steel. The device is applied to a coiling system comprising a side guide plate,a pinch roll and a coiling machine, the side guide plate and the pinch roll are sequentially arranged at the inlet position of the coiling machine. The method comprises the following steps that when the head of the strip steel is conveyed to an inlet of a finish rolling area, the side guide plate and the pinch roll in the coiling inlet area is controlled to be in a waiting position; a coiling mandrel of the coiling machine is controlled to generate a steel biting signal; the pinch roll is controlled to execute the pressure control mode, meanwhile, after first target time is delayed, the side guide plate is controlled to execute the pressure control mode, and the first target time is determined according to the camber length of the strip steel and the conveying speed of the strip steel; andafter the coiling mandrel
