Description
ABSTRACT
this study gives an overall assessment of the existing state of knowledge in the development of temperature models and its exploitation for process control in the continuous casting moulds. the study presents a model of cast steel in a continuous casting mould for two transverse surfaces of the work piece. The decision to model the two-dimensional problem was conceived from the results of experimental tests on the samples, which confirmed the desirability of this approach by exhibiting asymmetry of the temperature distributions in the edge dimensions of the test samples. The overall objective of the study, therefore, was to develop modelling and control techniques that are of potential interest to steel industry. Because the deformation process in a billet mill is a complex operation, this analysis is seen as an important research tool, complimentary to and capable of extending knowledge obtained from laboratory and on-line plant observations and measurements.
