| 摘 要： | 随着环保政策的加强，近年来无取向硅钢环保涂层产品产量迅速增长。环保涂层液成分与传统含铬涂液成分不同，表面质量稳定性差，极易出现各种缺陷。在生产某无取向硅钢过程中，无取向硅钢表面出现黑点缺陷，对产线稳定性以及产品成材率产生较大影响。通过宏观观察、扫描电镜（SEM）、能谱分析、现场模拟实验等，对黑点缺陷产生的原因进行分析，并针对此类缺陷提出控制措施，有效降低了黑点缺陷发生率。

| Abstract: | As the tightening of environmental protection policies, environmental protection coating products of non-oriented silicon steel have increased rapidly in recent years. The surface of the environmental protection coating liquid, of which the composition is different from that of traditional chromium-containing coating liquid, is poor on the quality stability and prone to various defects. In the process of producing a certain non-oriented silicon steel, black spot defects appeared on the surface, which impacted greatly on the stability of the production line and the yield of the product. Through macroscopic observation, scanning electron microscope (SEM), energy spectrum analysis, on-site simulation experiments, the causes of black spots were analyzed and control measures for such defects were put forward, which effectively reduced the incidence of black spot defects. |
