【摘要】：针对带钢切边过程现场与下游客户缺少统一的切边质量评价标准的问题,结合圆盘剪的设备与剪切工艺特点,经过大量现场试验与理论研究,在分析了带钢切边过程所存在的扣边、毛刺、切断比失衡三大主要质量缺陷的基础上,提出了一套有效实用的带钢切边质量评价方法。将带钢切边综合质量评价函数作为目标函数,圆盘剪间隙量与重叠量作为优化变量,开发出一套圆盘剪切边过程间隙量与重叠量综合优化设定的技术,并将其应用到某钢厂1 420生产线,大大提高了带钢切边质量,扣边、毛刺和切断比失衡缺陷改判率从技术应用前的0.52%下降到0.03%,同时保障了无返修,为企业创造了较大的经济效益,具有进一步推广应用的价值。
[Abstract]:In view of the lack of uniform quality evaluation standard for cutting edge in the field and downstream of strip cutting process, combined with the equipment and cutting process characteristics of disc shear, a large number of field tests and theoretical studies have been carried out. Based on the analysis of three main quality defects in the process of strip cutting, such as buckling, burr and disequilibrium of cutting ratio, a set of effective and practical methods for evaluating the quality of strip cutting are put forward. Taking the comprehensive quality evaluation function of strip cutting edge as the objective function and the disc shear clearance and overlap as the optimization variables, a set of optimization techniques for the optimization of gap and overlap in the process of cutting edge are developed. It has been applied to the production line of 1 420 in a certain steel plant, which has greatly improved the cutting quality, buckling, burr, burr and cutting ratio of steel strip. The rate of correction of the imbalanced defects has been reduced from 0.52% before the application of the technology to 0.03%, and at the same time, no repair has been guaranteed. For the enterprise to create greater economic benefits, has further promotion and application of value.
