Abstract
THE BREAK TEMPERATURE OF THE MOLD FLUX IS ONE OF THE MAIN PARAMETERS CONTROLLED IN THE STEEL CONTINUOUS CASTING PROCESS. THE OBJECTIVE OF THE WORK WAS TO DEVELOP A MODEL TO DETERMINE THE BREAK TEMPERATURE BY LINEAR REGRESSION. FOR THIS, DATA ON CHEMICAL COMPOSITIONS OF MOLD FLUXES REPORTED IN DIFFERENT WORKS WERE ANALYZED. WITH THE TREATMENT OF THE DATA, A MATHEMATICAL EQUATION OBTAINED BY LINEAR REGRESSION, BY L2 REGULARIZATION, WAS PROPOSED. THE RESULTS OBTAINED BY THIS MODEL WERE COMPARED WITH OTHER MODELS USED TO DETERMINE THE BREAK TEMPERATURE. THE STATISTICAL PARAMETERS OF MEAN ABSOLUTE PERCENTAGE ERROR, STANDARD DEVIATION, MEAN ERROR AND THE MAXIMUM ERROR, IN DIFFERENCE, OF THE MODEL VALUES AND THE MEASURED BREAK TEMPERATURE VALUES WERE EVALUATED. THE RESULTS SHOWED THAT THE MODEL OF THE PRESENT STUDY SHOWED LESS ERRORS AND LESS VARIABILITY OF RESULTS, IN RELATION TO THE CLASSIC EQUATIONS. BASED ON THE RESULTS, THE PROPOSED MODEL HAD THE POTENTIAL TO ESTIMATE THE BREAK TEMPERATURE OF MOLD FLUXES IN THE STEEL CONTINUOUS CASTING
