摘　　要：冷轧辊的加工过程是典型的多工序、多指标的多元质量控制过程,其关键工序的质量尤需严格控制.以某钢铁公司某种冷轧辊产品为例,描述了其加工环节,在对其进行工序分析的基础上,介绍在其机械加工环节中引进关键工序质量控制的必要性,利用改进的田口质量损失函来确定关键工序,并进行多工序过程能力分析及其指数计算,最后通过案例验证了此方法的合理性和有效性.Machining the cold roller blank is typically a multistage and multivariable quality control process, of which the quality of rome key stages requires highly strict control. Taking the cold roller blanks supplied from a certain steel plant as example, the main stages of their machining procedure are described and analyzed showing the necessity of quality control of key stages which are determined by the simply improved Taguchi＇ s quality loss function. Moreover, the MPCI is analyzed and computed, and the rationality and effectiveness of this method is verified through exemplification.
