UNIT-III : Learning Objective: To understand steel making process by Bessemer convertor. Construction and process details in acid and basic Bessemer convertors and openhearth furnance. Improvement and modification of the above process.
UNIT-IV : Learning Objective: To understand the principles of steel making by modern methods. Construction and process details in LD, LD-AC, Kaldo and rotor steel making processes. Bottom blown O2 processes. Combined blow processes. Continuous steel making process: – BISRA, IRSID & WORCRA Process. Construction details of electric arc furnace; production of steel. Induction furnance for steel making
UNIT-V : Learning Objective: To understand the principles of Solidification of steels and various Ingot defects.
Teeming Practices: – Direct, bottom and uphill Teeming methods. Casting pit side practice. Solidification of steels. Ingot defects and remedies; secondary steel making processes.Vacuum treatment of steels
UNIT-VI : Learning Objective: To understand about Continuous casting of steels.
Continuous casting of steels. Electro slag refining process. Vacuum arc remelting process. Brief outline of manufacture of alloy steels.
(Assessment: The student should be evaluated based on the assignments and objective tests. The student’s analytical abilities (with special focus on academically weak students) should be tested periodically in classes by giving problems). Emphasis should be given by conducting tutorial classes at the end of each unit.
