2、美观性要求，将用户需求指标化并定量化镀锡钢板表面光泽度控制目标值，根据光泽度测量原理建立金属表面光泽度理论计算模型，并经批量工业生产试验实测数据验证光泽度理论模型的正确性后，研究揭示钢板表面微观形貌对表面光泽度的影响机制，获得钢板表面微观形貌参数Ra值和Pc值对表面光泽度的影响规律。应用光泽度计算模型将用户要求的光泽度控制目标进一步转化为镀锡钢板生产中可控的Ra值和Pc值的控制目标，并针对某条国内最先进DI材镀锡钢板连续生产线，研究提出镀锡钢板表面光泽度控制的工艺方法和技术，投入长期生产稳定使用后使产品的光泽度

3、质量完全满足了用户的严格要求，创造了显著的经济和社会效益。关键词：视觉美观性；表面微观形貌；轧制转印；光泽度；光线跟踪中图分类号：TG33ControlofSurfaceGlossinessduringTemperRollingAimedatImprovingVisualAestheticsofTinplateZHANGQingdongZHANGBoyangLIRuiMALei(SchoolofMechanicalEngineering,UniversityofScienceandTechnologyBeiji
