Q. Recently, the India's largest blast furnace has commissioned at which place?
Answer:
Kalinganagar, Odisha
Notes: Tata Steel has commissioned India’s largest blast furnace at its Kalinganagar plant in Odisha as part of Phase II expansion. A blast furnace is a vertical steel shaft lined with fire-resistant materials, producing liquid metals by reacting air with metallic ore, coke, and flux. The furnace operates at over 300°C, with the hottest part water-cooled and supported by a steel frame. It produces pig iron from iron ore and is used for processing other metals like lead and copper. The process is continuous, with raw materials added at the top and molten metal and slag removed from the bottom.
Once started, it runs continuously for 4-10 years, stopping only for maintenance.
