self-sustain

The configuration of dissymmetrical CVC work roll contour and symmetrical conventional backup roll contour results in bad self-maintenance of backup rolls in downstream stands.

非对称的CVC工作辊与对称支持辊辊形配置易导致下游机架支持辊辊形自(保)持性差。

In the paper,control configs of level and temperature in detail were analyzed,fault of the existing configs was found and the updated config which contains self-maintenance circuit and interlocking circuit was risen.

物料容器的液位和温度等工艺变量控制是自控工程设计中经常遇到的问题,文章针对液位和温度工艺变量控制方案的关键内容分别进行详细分析,发现现有方案存在的缺陷和误区,提出了自(保)持电路加互锁电路的改进方案。
