摘　　要：踏步控制功能是热轧卷取机最为重要的功能之一,对卷取稳定性、设备使用寿命、带钢质量起着非常重要的作用。结合踏步控制原理,对踏步时序异常与助卷辊压力波动大的原因进行了详细分析;并通过对带钢头部跟踪、跳跃补偿量、控制增益参数、设备精度等进行调整和优化,降低了助卷辊压力波动,提升了助卷辊踏步控制稳定性,减轻了对设备的冲击,延长了设备使用寿命,提高了带钢质量。Step control function is one of the most important functions of hot rolling coiler,which plays a very important role in coiling stability,equipment service life and quality of strip steel.Combined with the principle of step control,the causes of abnormal step timing and large pressure oscillation of wrapper roller are analyzed in detail.By adjusting and optimizing the strip head tracking,jump compensation,control gain parameters and equipment precision,the pressure oscillation of wrapper roller is reduced,the stability of wrapper roller step control is improved,the impact on equipment is reduced,the service life of equipment is prolonged,and the quality of strip steel is improved.
