| Abstract: | Based on large amounts of measured data from a certain hot tandem rolling line,the deformation resistance models for 16 kinds of steel were obtained using simplex mathematical optimization method and the model parameters were determined.Rolling forces were calculated by the obtained deformation resistance formulas and the values were compared with those from actual measurement.The result confirms that the built model can comprehensively reflect the influence of various conditions on the rolling force.The model can not only correctly reproduce the sample data but also accurately predict the non-sample data. |
