为了准确掌握冷轧钢卷经过各工序时的缺陷位置,查找缺陷产生的机组和原因,研发了钢卷缺陷位置判定技术。通过从后往前推算钢卷缺陷所在的表面位置、长度位置、宽度位置,定位缺陷发生的机组和具体位置。该技术的应用为分析缺陷产生原因、降低钢卷缺陷发生率、减少批次质量事故起到重要辅助作用。 In order to get an accurate grasp of the defects of the cold-rolled coil after each process, find out the generating units and the reasons for the defects, and develop the technology of determining the location of the coil defects. By locating the surface position, the length position and the width position of the coil defects from the back, the generating units and the specific positions of the defects are located. The application of this technology to analyze the causes of defects, reduce the incidence of coil defects, reduce batch quality accidents play an important auxiliary role.
