Stable and efficient blast furnace operation with high PCI and low coke rate at Arcelor Mittal Flat Carbon W-Europe

摘要

Coke production capacity within Arcelor Mittal Flat Carbon W-Europe is not self sufficient for the total hot metal production. PCI was started up in 2004 at Bremen BF2 and Eisenhuttenstadt BF5, with a ramp up to 180 kg/thm in one year. A working group defined the BF operating conditions leading to stable and efficient operation at high PCI. At Florange BF3 PCI trials at 220 kg/thm were successful. At Dunkerque BF4 and Gent BFA and B, the PCI rate exceeds regularly 210 kg/thm.
