Steel composition model for continuous slab casting during a grade transition

The physical tundish water model was combined with the finite difference model to develop a model capable of accurately predicting the final slab chemistries during dissimilar grade transitions. The model was then used to help develop practices that will minimize the amount of material categorized as a transition bar. With the model, the relative merits of the practices were obtained. Currently, the model is being applied into the Level II computer system in which it is expected to make real-time calculations as to the chemical transition from one grade to the next, and will instruct the torch cutting computer to remove the transition material.
