热轧板酸洗机组中的拉矫机故障分析与改进

摘要

对热轧板酸洗机组拉矫机在生产应用中出现的问题,进行了分析并采取改进措施,通过增设博士刀装置消除带钢表面压印,改变出口转向辊的安装位置,减少带钢C型弯,改进工作辊装配、安装方式,使旋转接头及支座频繁磨损、烧损的几率大幅下降,改进下弯曲辊零位标定方式,带钢的弯曲量更加合理.对提高带钢板型质量起到了良好的效果.%The problems of tension leveller for hot-rolled pickling line in production were analyzed and improvement measures were taken.Strip surface embossing was eliminated by adding the doctor knife, the strip "C" bending deformation were reduced by changing the installation position of the exit deflector roll, the wearing or burning of rotating joint and holder were reduced by improving the way of work roll assembly and installation, the strip bending were more reasonable by improving the way of the below bending roll zero calibration.The improvements got good effects for improving the strip shape quality.
