The invention relates to the field of hot-rolled strip steel, in particular to a method for preventing a coiler from slipping and stacking steel. The method comprises the following steps that after a coiling machine receives steel type and specification information of rolled strip steel, the expansion and shrinkage pressure value of a coiling block is automatically calculated, so that the initial expansion time and the final expansion time are determined, and when the final expansion time of the strip steel is smaller than the opening time of a wrapper roller, the strip steel is a safe area. According to the method, normal coiling of the strip steel can be achieved by setting the expansion and contraction pressure and adjusting and setting the safety area, and the problem of steel stacking caused by slipping and coil scattering when the head of the strip steel is coiled is solved. 本发明涉及热轧带钢领域，具体是一种防止卷取机打滑堆钢的方法。该方法包括以下步骤，卷取机接收到轧制带钢钢种、规格信息后，自动计算卷筒的涨缩压力值，从而确定初涨时间和终涨时间，当带钢终涨时间小于助卷辊打开时间即为安全区。该方法通过设定涨缩压力和调整设定安全区，可实
