A novel tundish mixing model is proposed to predict the outlet concentration of the tundish during a grade transition. To enhance the efficiency and replication performance, the present model was designed to minimize the number of parameters to only one that needs to be tuned for easier application to new situations whereas the Huang and Thomas model has six parameters to be tuned. Two types of water model were employed to verify the present model, and the real grade mixed blooms were produced through a grade transition continuous casting. When the present tundish mixing model was applied to the cases of the water models and real bloom casting, the numerical results of the present model were found to be in good agreement of the experimental data, and the constant parameter <i>f</i> of the present model was found to be determined according to the tundish shape.
