Rolling deformation resistance prediction system of new steel based on clustering analysis

Abstract

A rolling deformation resistance prediction system of new steel based on clustering analysis belongs to the technical field of cold continuous rolling process control mathematical model system. The system aims at solving the problem that a deformation resistance analysis mathematical model based on hypothesis and simplification cannot offer a deformation resistance meeting requirements of set-up accuracy, thereby causing low set-up accuracy of the whole model system. The prediction system reads basic data of steel coils from a steel coil basic data sheet to determines key parameter objects of clustering analysis through correlation analysis between relative data of steels and rolling deformation resistance, and determines classification of new steels according to closeness degree of new steels to clustering centers of each steel, thereby determining predicted rolling deformation resistance of new steels corresponding to basic reduction rate. The prediction system solves the problem of low set-up accuracy of the whole model system due to low calculating accuracy of rolling reformation resistance, and improves product qualified rate and finished rate of cold continuous rolling strip steels.
