在连轧过程中，前后两架轧机存在金属秒流量差，当后架的秒流量大于前架时，造成前、后架之间的轧件受到前架轧机的拉力作用，此力通常称为张力。存在张力的轧制过程称为张力轧制。
根据该厂情况，将活套系统与轧机可控硅系统的参数合理匹配，实现了无张力轧制。
After the parameters of the looper system and silicon control system were matched reasonably with each other, the non-tension rolling was realized.
张力轧制是冷连轧生产的一个重要特点，张力控制的精度对轧制稳定性和成品带钢质量有着极大影响。
Tandem cold rolling is a producing technology with high efficiency and quality for cold rolling strip. It has a lot of equipment, and the control process that is complex.
分析了棒材轧制过程中微张力控制的基本原理，以及微张力控制在PLC程序中的实现方式。
The basic principle of micro tension controlling in rolling process of bar and the realization means of micro tension controlling in PLC program were analyzed.
