摘要: 热轧工作辊表层磨损状况的精准判定,对优化轧机效能具有显著工程价值。针对大尺寸辊面的成像难题,设计了融合双线阵相机与定制线光源的视觉采集系统,在换辊过程中稳定获取辊面图像。提出了基于约束动态时间规整的模板匹配算法,实现图像自动化采集。通过粗糙度、对比度、线性度与规则度构成的四维Tamura纹理特征向量有效表征了辊面磨损状态,结合极端随机树集成学习模型,对典型磨损形貌进行分类,准确率达95%。集成上述方法开发了辊面磨损智能检测平台,为热轧工作辊智能运维及工艺优化提供了新途径。

Abstract: Precise determination of hot rolling work roll surface wear conditions is critical for optimizing mill performance. To address the imaging challenges posed by large-sized roll surfaces, a vision acquisition system integrating dual line-scan cameras with customized linear light sources was designed, allowing roll surface images to be reliably captured during the roll changing process. A template matching algorithm based on Constrained Dynamic Time Warping is proposed to achieve automated image acquisition. Wear conditions are effectively characterized by a four-dimensional Tamura texture feature vector consisting of coarseness, contrast, linearity, and regularity. Furthermore, the classification of typical wear morphologies is achieved with 95% accuracy by employing an extremely randomized trees ensemble learning model. Finally, an intelligent roll surface wear detection platform was developed, providing a novel approach for the intelligent maintenance and process optimization of hot rolling work rolls.

Key words: hot rolling work rolls, surface wear assessment, machine vision, texture feature extraction, extreme random trees
