摘　　要：分析了某热轧线中用于检测立辊水平液压缸位置的磁尺数值偶尔发生跳变的原因,并进行了改进。认为磁尺清零位置程序计算故障是导致磁尺数值异常的根本原因。通过增加清零程序联锁、扩大出现极限值的范围等措施,使热轧立辊磁尺数值跳变得到根本解决。This paper analyzes the reason why the magnetic ruler value used to detect the position of the horizontal hydraulic cylinder of the vertical roller occasionally jumps in a hot rolling line,and improvement is made.It is considered that the fundamental reason for the magnetic ruler's abnormal value is the program calculating fault for the zero clearing position of the magnetic ruler.By adding the interlock of clearing program and expanding the range of limit value,the abnormal value of magnetic ruler of hot rolling vertical roller can be fundamentally solved.

关 键 词：热轧 立辊 宽度 磁尺 数值跳变 清零位置
