综述了双传感器表面检测系统的功能与组成,以及在首钢京唐公司冷轧2 230镀锌产线的使用现状,并详述了双传感器表面检测系统的技术优势、检测特点和应用价值。根据产品表面状态和质量要求对镀锌产品细分材料组和分类器优化,使表检仪的检测能力和分类水平大大提高。分析了几种典型缺陷在线阵相机和面阵相机拍摄下的各自特点及差异原因,增强了对于重要缺陷如翘皮、孔洞、夹杂、锌渣、硌痕、划伤等在表检仪下的认识和检出率,大大提高了镀锌带钢表面质量判定的准确性,也对促进镀锌产线的工艺改进起到了重要的作用。
The function and composition of the dual sensor surface inspection system are reviewed. The current situation of the 2 230 galvanized line in cold rolling in Shougang Jingtang Company is reviewed. The technical advantages, testing features and application values of the dual sensor surface inspection system are also described in detail. According to the product surface condition and quality requirements of the galvanized product subdivision material group and classifier optimization, so that the detection of inspection apparatus and classification level greatly improved. The analysis of several typical defects in the line array camera and area array camera under the shooting characteristics and differences between the reasons for enhancing the important defects such as warping, holes, inclusions, dross, scratches, scratches and other inspection instrument in the table Recognition and detection rate, greatly improving the quality of the surface of galvanized steel to determine the accuracy, but also to promote the process of galvanized production line played an important role.
