摘要
Cho and Kim(1)) proposed a simple model for predicting the amount of mix steel generated during ladle changes involving different steel grades in the same tundish. The authors solved the equations of the model numerically and validated their model for two different tundishes. This model has the advantage of having only one parameter, which should be calibrated for each tundish. In the present work, general analytical solutions were deduced for the Cho and Kim model. The solutions obtained are dependent on a single variable. This variable allows easy identification of the optimum operating parameters for the ladle change as it is illustrated by an application example. This work also investigated the meaning of the parameter of the Cho and Kim model in terms of chemical reactor theory.
