Hüttenwerke Krupp Mannesmann (HKM)
operating pre-retirementBF–BOF Integrated route · Duisburg, Europe, Germany
Hüttenwerke Krupp Mannesmann (HKM) 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 4.2 million tonnes per year. Its main products are coke, billet, pig iron, sinter, round bar, rolled, slab.
