Ironmaking & Steelmaking online course by Prof. Gour Gopal Roy | ...

NPTEL is offering online course for undergraduate students in Iron making and Steelmaking.

About the course:

• The emphasis on extractive metallurgy including iron making and steelmaking has been diluted significantly to accommodate newer courses on structure, properties and processing of different kinds of advanced materials.
• The number of faculty members in this discipline has also shrunk significantly in recent years.
• Iron making and steelmaking has been clubbed as single subject and even in some institute the subject has lost its core subject status and offered as an elective only.
• This is in contrary to the fact that India is going to be the second largest producer of crude steel in the world.

Course Layout:

• Week 1: Introduction: Various routes of modern steel making (BF-BOF, DRI-EAF, SR).Blast furnace Iron making: Shape of the furnace, Various reactions and zones in the blast Furnace Thermodynamics of Iron making, Direct & indirect reduction .Blast Furnace as an efficient counter current gas solid reactor and maximum carbon efficiency.
• Week 2: Overall heat and Material Balance in Blast Furnace. Rist Diagram based on oxygen balance, Rist Diagram based on heat & Material balance
• Week 3: Blast Furnace as a two stage reactor. Predictive model for coke rate in blast furnace.
• Week 4: Aerodynamics in Blast Furnace (pressure drop, fluidization, channeling, Flooding).
• Week 5: Burden preparation (sintering, pelletization, coke making). Testing of raw materials
• Week 6: Burden distribution in Blast Furnace. Auxiliary injection, fuel efficiency and productivity in Blast furnace.
• Week 7: Thermodynamics of steelmaking. Introduction to LD steel making (process, emulsion, decarburization, catch carbon technique, impurity & slag evolution)
• Week 8: Hybrid steel making. Modern EAF/IF steel making. Secondary Steel making: Thermodynamics & kinetics of deoxidation
• Week 9: Secondary steel making: Vacuum treatment of steel and processes, gas stirring.
• Week 10: Secondary Steel making: Ladle desulphurization, inclusion modification by calcium treatment. Inclusion control by optimizing upstream operating parameters.
