摘　　要：热轧产品质量终判在制造执行系统(manufacturing execution system, MES)中进行,采用取样方式进行检验,难以满足客户对生产过程把控的需求。为了将过程参数对产品质量的影响准确表征出来,本文提供质量过程判定与评级方法,在传统基于人工经验规则判定的基础上,加入了去头尾规则,并对判定结果进行分项评级后再综合评级。现场实际应用中,对比之前单一基于人工经验规则判定方法,该方法为MES质量终判提供了更全面、精细、精准的数据支撑,降低了质量缺陷卷的流出率,提高了客户满意度,提升了企业竞争力。The final judgment of hot rolled product quality is carried out in the manufacturing execution system(MES),and the sampling method is used for inspection,which is difficult to meet the needs of customers for production process control.In order to accurately characterize the influence of process parameters on product quality,the quality process judgment and grading method provided in this paper adds the head and tail removal rule on the basis of the traditional judgment based on manual empirical rules,and then comprehensively evaluates the judgment results after sub item grading.In the actual application of the field,compared with the previous method based on manual empirical rules,this method provides more comprehensive,refined and accurate data support for MES quality final judgment,reduces the outflow rate of quality defected coiles,improves customer satisfaction,and enhances enterprise competitiveness.
