Abstract: Based on 3D-FEM simulation, a model on influence of strip wave-shape upon the running deviation in the continuous annealing line was developed to improve the strip passing stability. A two-step model of FEM on hot strip rolling calculating the lateral flow of the metal improved the accuracy of strip shape control system.

Abstract: The stochastic excitation power spectral density (PSD) model and ARMA time series model are established based on the stochastic rolling force acquisition data, which is processed into stationary, normal and zero mean from a aluminum hot strip tandem mill. Characteristics of rolling force ARMA time series models are discussed by means of random process theory. The rolling forces PSD function of facilitating engineering application is obtained by utilizing Levenberg-Marquardt combined with generalized global planning algorithm, and the stochastic excitation model is established. It provides the basis for the prediction of rolling force.
