mould level control meaning in English
锭模内钢液面控制
Examples
- The article have been discussed theoretically for some technology control system of continous casting , for example mould level control system , electromagnatic mould stirring system , soft - reduction , the secondary cooling water control ect
并对连铸一些特殊工艺控制如结晶器液位控制系统、结晶器电磁搅拌、轻压下、二冷控制等进行了理论探讨。 - Although the fuzzy self - tuning pid parameters controller has been applied in many control fields , it not be reported that the fuzzy self - tuning pid parameters controller be applied to the mould level control system , according to the present information
虽然pid参数模糊自整定控制器广泛应用于许多领域，但是，据目前所掌握的资料和信息来看，将pid参数模糊自整定控制器应用到结晶器液位控制尚未见报道。 - Based on the careful analysis on the difficulties , which the mould level control system encounters , and scrupulous research on many controllers which applied to the mould level control system , a fuzzy self - tuning pid parameters controller is adopted in this paper , which aimed at taking place the old pid controller for which bad control effect
本论文在仔细分析了结晶器液位控制所面临的困难和深入研究了多种结晶器液位控制方法的基础上，结合武钢二炼钢3 #连铸机液位控制系统的实际情况，设计采用一种pid参数模糊自整定控制器，用来代替传统的pid控制器。 - The control system of mould level is crucial to improve the slab quality in the continuous casting process , pid controller is used in the traditional mould level control , and it has some defaults , such as : at the start - up or finishing period of casting or during the changeover of tundish , pid control has a bad effect , its overshoot is large and its transient time is long ; the erosion of the tundish stopper and the submersed nozzles lead to the accuracy of control become bad ; the abrupt falloff of block in the submersed nozzles makes the level acutely fluctuate , and pid control can not overcome the disturbances resulted from the change of casting speed
结晶器液位控制系统是提高连铸产品质量的关键环节，传统的连铸机液位控制方法采用常规的pid控制，存在如下不足：开始、结束浇注和换中间罐浇注时，控制效果差，超调量大，过渡时间长；塞棒头和浸入式水口被腐蚀后引起控制精度差；浸入式水口堵塞物的突然脱落所引起的液位剧烈波动；无法克服拉速波动引起的扰动。
