The course focuses on understanding the tundish operations during continuous casting steelmaking process. Tundish is the last metallurgical vessel through which molten metal flows before solidifying in the continuous casting mold. During the transfer of metal through the tundish, molten steel interacts with refractories, slag, and atmosphere. Thus, understanding about the operations inside the tundish and the methods to model these operations help in making effort towards increasing the productivity in terms of good quality end product and decrease in rejection of the products due to different defects.
