Abstract

The present invention provides a method for tracing the cause of sintering non-optimal operating performance based on parameter isolation. First, the present invention uses the process capability index as the evaluation index of operating performance, and integrates the cases whose operating performance evaluation grade is "excellent" into a case library. Then, the detection parameters are isolated in turn, and the matching cases of the cases to be analyzed after the isolation parameters are obtained. Finally, the difference between the case to be analyzed and the matching case in each isolation parameter is obtained, and the isolation parameter with the largest difference is taken as the cause of the non-optimal operating performance. The invention utilizes actual operation data to build a case base, and provides powerful guidance for operators to find out the cause of non-optimal operation performance.

Description

technical field [0001] The invention relates to the field of intelligent evaluation and control of the iron ore sintering production process, in particular to a method and system for tracing the cause of non-optimal sintering performance based on parameter isolation. Background technique [0002] Operation status evaluation refers to making a judgment on the pros and cons of process operation performance under the premise of safe production, and tracing the reasons for non-optimal operation status to guide operators to make production adjustments. In essence, the operation status evaluation is to further divide the normal production process into multiple grades, such as excellent, good, general, poor, etc. A more refined sub-category (that is, the status level) enables the production managers and actual production operators of the enterprise to have a more in-depth and comprehensive grasp of the operation of the process. When the current operating state is not optimal, it i...
