平整机轧制力特性控制技术的改进

Improvement of Temper Mill Rolling Force Characteristics Control Technology

在平整机延伸率控制的几种方式中,通过调节轧制压力实现延伸率的自动控制方式占据了非常重要的地位,在冷连轧机的最末机架中也经常用到恒轧制力控制模式。以某厂平整机为例,通过对平整机液压压下控制系统(HAGC)的性能测试以及对测试结果的分析,提出改善和提高轧制力控制特性的新策略和新方法,以提高产品的性能和质量。

The automatic control mode for Temper Mill ehmgation control via screw-down roll force adjustment plays a very important role in all Temper Mill elongation control methods, and the constant roll force control mode is also frequently used in the last stand of coht rolling tandem mill. Taking a factory Temper Mill as an example, a new strategy is explained for improving and enhanc, ing the roll force control characteristics to improve the performance and quality of the products based on the performance test resuhs of hydraulic pressure control system（HAGC）.
