摘要
针对超深冲热镀锌冲压开裂问题，利用Minitab软件，采用DOE实验设计的方法，分析了成分、退火温度、平整率对材质性能的影响；通过实验结果得出了屈服强度及抗拉强度的回归公式。利用回归公式确定了工艺优化方案，实现了产品质量改进，满足了用户要求。
In this paper, in order to solve the stamping cracking of Extra-Deep Drawing hot-dip galvanized, we use the DOE method to analysis composition, annealing temperature, smooth rate and their impact on the performance of the material. According to the research results, we found the regression formula of yield strength and tensile strength. By using the regression formula, the process optimization scheme is determined, and the product quality is improved, which meets the requirements of the users.
