Abstract

Since last few years study of CO2 emission in every sector has become very important due to severe global climatic changes. Steel sector contributes to about 7.2% of global CO2 emission. Across the world steel is manufactured through BF-BOF route and Electric furnace route. Further, electric steelmaking is divided in electric arc furnace steelmaking and induction furnace steelmaking. Ample data is available for BF-BOF and EAF route, but for induction furnace steelmaking available data is very less. Induction furnace steelmaking is a unique way of steel production. The route is very much popular in Asian countries. Induction furnace uses steel scrap for steelmaking. Considering these factors, the purpose of present study is to generate the data of CO2 emission for induction furnace steelmaking. It was observed that at steel melting shop CO2 emission for induction furnace is only 3-5 kg CO2 /ton of steel. Comparison of induction furnace data is also done with the arc furnace steelmaking and BF-BOF steelmaking which have high amount of CO2 emission per ton of steelmaking.
