摘　　要：马鞍山钢铁股份有限公司电炉厂圆坯开坯机实现全自动轧钢,其压下电动机、推床和翻钢钩通过自动位置控制(APC)完成精确定位。详细阐述了自主设计的APC功能块的参数设定与计算方法,主要包括速度给定和减速距离的计算。经实际应用证明,该功能块定位精度高,完全满足工艺要求,为自动轧钢提供了有力保障。Automatic rolling of round billet breakdown mill is realized in MaSteel electric furnace fac- tory. The screwdown motor, manipulator and hook tilter are piecisely positioned by the automatic posi- tioning control （APC）. The parameter setting and calculation methods of APC function block mainly including the calculation of speed reference and deceleration distance which are designed by ourselves are described in detail. Practical application shows that the function block has high positioning accura- cy,fully meets the technical requirements, and provides powerful support for automatic rnilinr,
