The authors first selected HW * in CIE1976 L *a *b * color space as evaluating indices of surface quality of stainless steel cold rolling coil after pickling. The orthogonal test and ANOVA were carried out to the pickling process parameters.

• 首次选用 CIE1976 L* a* b* 色空间中的白度 H W* 作为不锈钢冷轧卷酸洗工艺后表面质量的评价指标 ,对酸洗工艺参数进行了正交试验和方差分析 ,通过 F检验判定出各工艺参数的显著性及其顺序 ,给出了酸洗工艺参数的优化结果 ,以指导不锈钢的实际生产工艺。
