ArcelorMittal Dunkerque
operatingBF–BOF Integrated route · Dunkerque, Europe, France
ArcelorMittal Dunkerque makes steel by the integrated route: iron ore is smelted into liquid hot metal in a blast furnace, then refined into crude steel in a basic oxygen furnace. The liquid steel is solidified into semi-finished shapes by continuous casting. The plant has a crude steel capacity of about 6.8 million tonnes per year. Its main products are slab, coil, hot rolled.
