Abstract:The abnormality is a main factor that affects sintering process.In order to diagnosis abnormalities in sintering process with accuracy and eliminate them in time,an expert system for diagnosing abnormalities in sintering process has been established on the basis of combining mathematical model and fuzzy logic with expert system,and successfully applied to sintering real-time diagnosis on-line. The results obtained are satisfying.In this paper,the essence of abnormality diagnosis in sintering process is analyzed,the evidence sets of 17 typical abnormalities in sintering process are investigated by the acquisition of knowledge.The fuzzy diagnosis model is studied,and the general diagnosis scheme and general structure of the simplified blackboard structure for diagnosing the abnormality type,cause and countermeasure are put forward.The software developed with Visual C++ programming language is successfully applied in on-line operate guiding of sintering process in a large plant, and the results prove that this expert system is good forreal-time application and practicality. The correctness rate of diagnosis and operation guiding is above 85%.
