【摘要】：本文以冷轧UCM轧机FGC断带和末机架轧辊粗糙度均匀性为研究对象,通过实践与理论分析完成冷轧UCM轧机生产稳定性的相关研究。针对酸轧FGC断带,主要通过对电气二级程序中FGC过渡轧制表优化和在一级和二级程序中将剪切时序提前以及针对特定钢种做自动抬辊缝功能,最终通过统计学的方法,将容易发生断带的钢种进行预判,增加合理过渡料降低断带风险。末架轧辊粗糙度均匀性研究,主要利用minitab软件进行,对所有影响因素进行分析,由FMEA打分,筛选因素,随后进行DOE设计实验,找出主要影响因素,运用相应曲面找到合理打毛参数配比,最终确定的毛化工艺参数为横移速度为45mm/min、通电时间为17us、断电时间为41us,达到Ra为3.6um±0.15的轧辊粗糙度合格率在80%以上。
[Abstract]:In this paper, the coarseness uniformity of cold UCM rolling mill FGC break and end stand roll is taken as the research object, and the production stability of cold UCM mill is studied by practical and theoretical analysis. In view of acid rolling FGC break strip, by optimizing the FGC transition rolling table in the electrical secondary program, advancing the shearing timing in the first and second grade programs, and making automatic lifting roll gap function for specific steel grades, the final statistical method is adopted. In order to increase the reasonable transition material and reduce the risk of broken zone, the steel grade which is prone to break zone is forecasted. The research on the roughness uniformity of the final roller is mainly carried out by using minitab software. All the influencing factors are analyzed, and the factors are scored by FMEA and screened. Then, the design experiment of DOE is carried out to find out the main influencing factors. Using the corresponding surface to find out the reasonable ratio of tapping parameters, the final process parameters are 45 mm / min traverse speed, 17 us. electrification time and 41 us. the qualified rate of roughness of roller with Ra being 3.6um 卤0. 15 is over 80%.
