- Kobe Steel's Consideration: Kobe Steel is considering building a large electric arc furnace to replace one of its blast furnaces in Kakogawa, western Japan, to accelerate its decarbonization efforts.
EAF BS BF-BOF
- Steel is produced via two main methods: the blast furnace-basic oxygen furnace (BF-BOF) route and electric arc furnace (EAF) route. Variations and combinations of production routes also exist.
- The key difference between the routes is the type of raw materials they consume.
- For the BF-BOF route these are predominantly iron ore, coal, and recycled steel, while the EAF route produces steel using mainly recycled steel and electricity.
- While EAF steelmaking relies on electricity and recycled metals, Blast Furnace/BOF depends on raw materials like Iron Ore and Metallurgical Coke as part of a process where oxygen is blown into the furnace at a high velocity. This process uses significantly more energy, depends on using raw materials and is limited in its evolution towards more sustainable
- By using recycled steel as part of the EAF, we’re contributing to a circular economy—producing less landfill waste, using less energy and generating fewer emissions from production, transportation and shipping.
Advantages of EAF over BF-BOF
- Electric arc furnaces may have a lower share of overall steel production but have many advantages over the traditional BF-BOF route. Some of these advantages are:
- Flexibility in terms of production as per the changing market demand
- Flexibility in terms of the variety and quantity of raw materials/charge they accept
- They are considered more efficient compared to blast furnaces
- They can produce steel with a much lower level of greenhouse gas emissions compared to the blast furnace route. They can take 100 per cent steel scrap as raw material and also have the possibility to use green hydrogen-based sponge iron as raw material, which are the two cleanest steel-producing routes worldwide.
- Capable of producing a whole range of steel products
- Have a low capital cost compared to BF-BOF
