Green BOF steelmaking — How to increase scrap rates and reduce CO2 emissions
Fluctuations in raw material availability and prices as well as increasing pressure to reduce CO2 emissions are challenges that integrated BOF steel producers are currently facing. In this webinar you will learn more about the charge mix limitations in integrated BF – BOF steelmaking and the impact of higher scrap rates on steel quality and productivity. Based on current reference cases, we will show how different solutions for increasing BOF scrap rates can help to reduce CO2 emissions and increase raw material flexibility. Starting from a small increase in scrap rate with low budgets and moderate CO2 reduction up to a massive increase in the scrap rate with large investments and maximum CO2 reduction, different solutions (increase of post combustion, scrap preheating, external scrap melting) will be presented and compared. Whatever the plant setup and the investment budget – this webinar will show you a path toward greener BOF steelmaking.
Target audience:
- BOF steelmaking managers
- BOF process experts and technology leaders
- BOF operators
- Raw materials purchasing department
- Operation decision maker
- Integrated plant manager
Key takeaways:
- Understand the limits of integrated BOF production route in regard to charge mix and heat balance (learn from renowned university professor and steelmaking industry expert).
- See the influence of increased scrap rate on steel quality and productivity on reference cases.
- Learn about new ways and future trends how to increase scrap and reduce CO2 emissions within existing plant set up.
- Comparison of different solutions to increase scrap rate for a gradual transformation towards green steelmaking from small to large CAPEX.
Speakers
JOHANNES SCHENK
Chair of Ferrous Metallurgy, University of Leoben
Johannes holds a PhD in process engineering from Graz University of Technology. After university he joined Primetals Technologies (VAI at the time) in 1990 and lead the ironmaking business and R&D for smelting reduction solutions. In 2008 he was appointed the head of the Chair of Ferrous Metallurgy at University of Leoben.
