DC4: Future converter steelmaking based on hydrogen-reduced DRI
Project title: Future converter steelmaking based on hydrogen-reduced DRI (WP1)
Host Institution: TU Delft
Country: Netherlands
Supervisor: Yongxiang Yang (TUD) – Co-supervisors: Neslihan Dogan (TUD), Bapin Rout (TATA), Frank Schrama (TATA), Martin Kendall (HEEL)
Objectives:
- Determine the lower limit of carbon in the hot metal needed for converter refining of phosphorus and nitrogen;
- Determine the impact of other elements (Si, P) in H-DRI hot metal on converter refining;
- Engineer the converter slag to enable the refining of H-DRI hot metal;
Expected results:
- Correlation between carbon concentration in hot metal and dephosphorisation and denitrogenisation;
- Engineered slag composition, including different flux additions;
- Advise on converter process control with different future hot metal compositions;
