摘要
某无取向硅钢板在生产过程中表面出现涂层缺陷。采用宏观观察、化学成分分析、硬度测试、能谱分析及涂层厚度测试等方法对缺陷产生原因进行了分析。结果表明:该无取向硅钢板在生产过程中进行了宽度规格的切换,生产窄硅钢板时残留的非环保涂料与生产宽硅钢板时板面上的环保涂料不相容,导致了该无取向硅钢板涂层缺陷的产生,出现了涂层不均的现象。
Coating defects appeared on the surface of a certain non-oriented silicon steel plate during production.The causes of the defects were analyzed by macro observation,chemical composition analysis,hardness test,energy spectrum analysis,coating thickness test and so on.The results show that the width specification of the non-oriented silicon steel plate was changed during production.The residual non-green coatings of narrow silicon steel plate was not compatible with the green coatings on the surface of wide silicon steel plate during production.As a result,the coating defects of the non-oriented silicon steel plate were produced and the coatings were uneven.
