摘　　要：分析了影响厚板定尺剪切精度的设备和控制因素,通过采用加强设备维护、改进剪切工艺、增加定尺机的标定与校准限位、优化测长辊参数、编制测长自学习程序等措施后,厚板成品剪切的长度精度偏差由原来的3．0‰下降至0．4‰以下。Influence factors ofequipment and control system on shearing accuracy ofheavy plate were analyzed. The length shearing deviation was decreased from 3.0‰ to 0.4‰ by appling some measure.s, such as strictly maintaining equipment,improving shearing technology and optimizing parameters of length roll, etc.
