In this paper, an integrated KPLS (Kernel Partial Least Square) prediction model for steel mechanical property is proposed. To eliminate the heterogeneity among variables in the hot rolling process, the KFA (Kernel Factor Analysis) is used to obtain the latent factor load vectors. Then the variables with large factor load were clustered into subsets, and the KPLS components are extracted respectively for each subset variable and target variable. Finally, the KPLS results of all subsets were integrated as input, and an integral KPLS prediction model is constructed with the target variables. An application study was carried out on the real production data of a steel-making plant. The experimental result shows that the precision of the presented method is greatly improved.
