摘　　要：对铝型材氧化着色处理过程中因色差造成的一次合格率偏低的问题进行现场调研,找到了问题产生的主要原因是槽液调配不及时槽液消耗不稳定及上架挂面积过大,实施了改进措施后,铝型材合格率由97.29%提高到99.25%。The issues of aluminum profiles with low first-time qualification rate of oxidation coloring are investigated on site in the paper, and it is found the main reasons for the problem is that the liquid of tank is not adjusted in time and is not consumed stably, and the shelf area is oversize. After improving meas- ures are worked out and implemented, the qualified rate of aluminum profile has been increased from 97.29% to 99.25%.
