张力控制在1250mm冷连轧中的研究与应用
|
摘要
冷轧薄板属于高附加值钢材品种,是汽车、机械、建筑、电工电子、食品等行业必不可少的原材料。冷连轧是一种高效、优质的冷轧生产工艺,其设备众多、控制过程复杂。在冷轧薄板的生产过程中,连轧机架间张力控制的精度直接影响着带钢产品的质量,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。因此,张力控制具有重大的实际价值。
文中阐述了冷轧带钢机架间张力产生的原因,并分析了机架间张力的控制方式和张力自动控制的基本原理。通过自动张力控制系统,即ATC(Automatic tension control)系统的详细分析研究,结合福建永大集团凯西钢铁公司的1250mm五机架冷连轧机项目的设计要求,对ATC控制模型做出了设计、调试和改进。从三个月的调试到正常投产,表明这种控制方式的优越性和实用性,并对其中的不足之处给出了说明。
最后,根据轧机现场中存在的一些不确定因素,阐述了ATC控制系统在调节中对系统性能指标的影响,给出了现场的调试结果,找出应用的不足之处。
张力自动控制ATC对于提高控制精度,加强成品带材的质量都有着非常重要的影响,因此加强ATC的应用研究必将成为推动板带钢轧制现代化的重要保证。
Cold sheet metal is a product that yield a high added value, and the essential raw materialsof automobile, machinery, construction, electronic, food and other industries. Tandem coldrolling is a highly efficient, high-quality cold-rolled production technology and it has numerousequipment,complex control process. In the process of strip production, the control precision ofinterstand tension has a directly impact on the quality of steel strip products and rolling stability.
This article expatiates the main reason which lead to the interstand tension and analyzesthe control mode and basic principles of ATC（Automatic tension control）on detail.Coupledwith the requirements and development of technology of cold sheet metal rolling,it analyzesand studies the automatic tension control system (ATC), discusses the primary principlesand control methods of current ATC systems. With further study of ATC systems and designingrequirements of 1250mm 5 stands tandem cold mill project in FuJian Casey Steel plant, we alsoimprove the ATC control model and debugging in the field. With half three months' debugging,the mill puts into production normally. It fully indicates the superiority and practicability of thiscontrol method and also shows the shortage of it.
According to the existing uncertain factors in the field, it discusses the influence on thesystem performance which was caused by ATC regulation. In the meanwhile, it discusses theinfluence on the final control results which was caused by ATC measuring apparatus and findsout the deficiency of its application.
Automatic tension control (ATC) has a great impact on increasing control precision andenhanced the quality of sheet metal production. Accordingly the study of intensifying theapplication of ATC will be important guarantee of promoting sheet rolling modernization.
