Applying Heat Transfer Models to Estimating the Hot Strip Temperatures in Steel Rolling Mill Lines
Original language description
Particularly the growing demands on energy savings have led to the design of more compact steel hot-strip mills with fewer rolling stands. This trend, however, brought about higher demands on the load in the single rolling stands and therefore more reliable and accurate heat transfer models need be applied particularly in controlling the rolling process in its hot-strip phase. The paper deals with a strip temperature estimation based on models of heat transfer in the decisive, i.e. finishing, nodes of the hot strip mill line. The model is assigned to predict the temperature drops both in the rolling stand areas and in the inter-stand spaces. The model application is conceived as an original steady-state observer the output of which provides the estimates of the strip temperature drops. Then the temperature drop models are applied to achieving the model based observer with state delays. The resulting observer scheme helps to overcome the problem of uncertainty of the overall heat transfer coefficients on the strip surface. The presented model-based temperature estimation is shown on an application example of a hot strip mill line with seven rolling mills.
