Application of quality process judgment and grading method for hot continuous rolling
The final judgment of hot rolled product quality is carried out in the manufacturing execu-tion 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 man-ual 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 fi-nal judgment,reduces the outflow rate of quality defected coiles,improves customer satisfaction,and enhances enterprise competitiveness.
