Modelado del Proceso Convencional de Colada Continua de Aceros Libres de Interticios [PDF]
Información tecnológica, 2010 The purpose of this work was to develop a mathematical model able to simulate the continuous casting process of IF steel (Interstitial Free).and to determine the optimum operating conditions. The model formulation involves the momentum equations of liquid and solidified materials coupled with the temperature evolution of the slab.
