Based on the new model, the design steps are given. The LS-SVM model is able to fit the complex nonlinear functional relation between the input and output. Roll speed, steel plate length, width, thickness, upper and lower temperature of furnace, surface temperature of steel plate in previous moment are selected as inputs, surface temperature of steel plate in this moment is chosen as outputs. The very good forecast effect is obtained when on-site production process data are taken as the training samples to train the model, and then the data samples of model test are selected to simulate it. The model is used to calculate the steel plate surface temperature of the heat treatment furnace. The result indicates that the model is quite simple, and has the strong predictive ability and a broad prospect of applications., authors=LI Jing, XIE Ting, authorsList=LI Jing;XIE Ting,
