Modeling of tundish steelmaking process in continuous casting

Indian Institute of Technology Roorkee and NPTEL via Swayam


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.     INTENDED AUDIENCE : Mechanical/Metallurgical/Production PREREQUISITES : Fluid mechanics, heat transfer, numerical methods, manufacturing processes INDUSTRY SUPPORT : Steel Industries like SAIL, Tata Steel, Jindal Steel etc.


COURSE LAYOUT Week 1 : Introduction to continuous casting tundish, Types of tundish, tundish metallurgy Week 2 : Concept of physical modeling, Similarity and dimensional analysis Week 3 : Stimulus response techniques, Residence time distribution curves Week 4 : Fluid flow fundamentals, Navier stokes equations Week 5 : Modeling turbulent flow, Turbulence models Week 6 : Review of heat and mass transfer models, Numerical methods for solving governing equations Week 7 : Modeling study of fluid flow and mixing inside tundish Week 8 : Modeling study of Grade intermixing and inclusion floatation behavior in tundish
