基于力学分析的热轧张力压头使用问题研究

Application research of hot mill looper loadcell based on the mechanics analysis

张力控制是热轧工艺精轧区域重要的控制参量之一,为实现高效的张力控制必须要有精确的张力测量设备。由于张力压头是首次在宝钢的热轧工艺使用,在测量原理和维护方式等方面均无经验可参考,在使用过程中也出现了一些问题。通过对张力压头和活套进行受力分析,详细阐述力的整个传递过程,逐一解释使用中出现的问题和异常现象,如寻找最佳的校零位置、张力负值问题的发生原因等。同时据此也建立自主的维护和使用技术,为精轧的稳定高效运行服务。

Tension-control is one of the important parameters in finishing area of the hot rolling,In order to realize efficient tension-control,there must be accurate tension measuring equipment.Because of the first time that the looper loadcell is used in Baosteel hot mill,not only the measuring principle,but also the maintenance method etc,no experience can be referenced in use process,so there are some problems. Through the mechanics analysis on looper and loadcell,the transfer process of the force was detailed elaborate,the problems occurred and the abnormal phenomenon in the use were explained one by one,such as the search for the best zeroing position and tension negative problem causes. At the same time to establish the independent maintenance and use of technology,to supply the stable and efficient service for finishing.
