张力辊的张力控制在冷轧连续退火线中应用十分普遍,也是不可缺少的。T400工艺板可以实现张力辊的建张、张力闭环、负荷平衡、断带检测、电机常用的逻辑控制等,且在使用上完全以参数化编程,可以广泛应用在冷轧连续退火线的控制系统中。实践表明以T400工艺板为核心的直接张力控制系统具有结构简单、张力控制精度高、故障率低、维护方便等特点。 Tension roller tension control in cold-rolled continuous annealing line is very common, but also indispensable. T400 technology board can realize the tension roller building Zhang, tension closed loop, load balancing, broken belt detection, the motor commonly used logic control, and in the use of fully parametric programming, can be widely used in cold rolling continuous annealing line control system in. Practice shows that the T400 technology board as the core of the direct tension control system has the advantages of simple structure, high tension control accuracy, low failure rate, easy maintenance and so on.
