镀锌生产线新型张力控制系统的设计与研究

Design and Research of New Tension Controlling System of Galvanized Line

结合首钢某冷轧厂镀锌生产线出口段张力控制系统改造项目，介绍了新型张力控制系统的构成、工作原理及开发中应用的主要控制技术，并通过过程数据处理获取数据采集系统对实际生产中的重要参数进行了采样和分析。结果表明，新型张力控制系统运行稳定可靠，解决了镀锌生产线出口段带钢易滑落、头部划伤和采样长度精度差等问题。

Combined the project of tension controlling system reconstruction at the exit section of Continuous Galvanizing Line in Shougang a certain cold rolling mill, this paper introduces the new tension controlling system constitution, operating principles and main application controlling technology during developing. In addition, the important parameters in actual production are collected and analyzed in virtue of process data acquisition system. The results show that new tension controlling system has a stable operation and can solve the problems of strip sliding, strip head scratching and bad sampling length precision at the exit section of CGL.
