鞍钢技术2023年第3期ANGANGTECHNOLOGY研究与开发冷轧先进高强钢表面色差缺陷综合控制技术研究王植",孙荣生²,王静3,蔡顺达²,李岩²,刘仁东2（1.鞍钢股份有限公司冷轧厂，辽宁鞍山114021；2.鞍钢集团钢铁研究院，辽宁鞍山114009；3.鞍钢股份有限公司系统创新部，辽宁鞍山114021）摘要：针对C-Si-Mn系冷轧先进高强钢成品表面色差无法满足下游客户涂装的问题，采用扫描电镜（SEM）、能谱仪（EDS）、X射线衍射仪（XRD)及激光共聚焦显微镜（LSCM)等手段分析缺陷产生原因。结果表明，成品表面色差缺陷为热轧、酸洗等多道工序综合作用的结果。通过优化板坏加热工艺、增强除鳞效果及酸洗能力，制定表面色差综合控制技术，表面色差缺陷得到了有效控制，满足客户使用要求。关键词：冷轧先进高强钢；表面色差；综合控制技术中图分类号：TG33D01:10.3969/j.issn.1006-4613.2023.03.004StudyonComprehensiveControlTechnologyforSurfaceColorDifferenceDefectofCold-rolledAdvancedHighStrengthSteelsWANGZhi',SUNRongsheng’,WANGJing",CAIShunda?,LIYan?,LIURendong?(1.ColdRolledStripSteelMillofAngangSteelCo.,Ltd.,Anshan114021,Liaoning,China;2.AnsteelIron&SteelResearchInstitutes,Anshan114009,Liaoning,China;3.SystemInnovationDepartmentofAngangSteelCo.,Ltd.,Anshan114021,Liaoning,China)Abstract:InordertosolvetheproblemthatthesurfacecolordifferenceoftheC-Si-Mnseriescold-rolledadvancedhighstrengthsteelscouldnotmeetthecoatingrequirementsaskedbydownstreamcustomers,thecausesofcolordifferencedefectwereanalyzedbymeansofscanningelectronmicroscopy(SEM),energydispersivespectroscopy(EDS),X-raydiffraction(XRD)andlaserconfocalmicroscopy(LSCM).Theanalyticalresultsshowedthatthecolordifferencedefectoffinishedproductsurfaceswascausedbythecomprehensiveeffectofthesemultipleprocessessuchashotrollingandpickling.Sobyoptimizingtheslabheatingprocess,improvingthedescalingeffectandpicklingcapacity,anddevelopingthecomprehensivecontroltechnologyforsurfacecolordifference,thesurfacecolordifferencedefectwaseffectivelycontrolledandthustherequirementsbycustomersweremet.Keywords:cold-rolledadvancedhighstrengthsteel;surfacecolordifference;comprehen-sivecontroltechnology近年来，在碳达峰、碳中...
