RESUMO

In this work, a nunerical mode! based on the finite difference technique was developed permitting to determine the a thermal field evolution during solidification along the continuous casting process. The model predictions were compared to experimental results as well as to those furnished by other models found in literature. An interaction between a knowledge base and the mathematical model was carried out in order to analyse steel billet quality. As a result of literature search and interaction with knowledge provided by a continuous casting industry, the knowledge base was structured with information that correlate quality problems with process parameters. The numerical model communication with the knowledge base was established by employinga computer program in order to permit automatic solutions of optimized operating conditions to be attained. The model was applied to analyse real casting operation of a steel plant equipment as well as to designan optimized continuous billet casting system by employing recent trends of larger mould lenght and higher production speeds
