Abstract: Based on the investigation of experimental data sampled from φ250×6 semi-continuous bar mill, the mathematical models for continuous rolling steel angles have been studied. The structure of model is identified theoretically and the coefficient of model is estimated by statistical analysis of the experimental data. By the method of dispersing numerically and coinciding with a function, a program of simplifying the shape rolling model is proposed.
From the results of off-line simulation, it is proved that the prediction of the model established by the upper method has been found to agree, closely with the experimental data. The accuracy of the model may be further improved by using the adaptive control system.
