1/5/2013· In the best hydrogen-based steelmaking breakthrough route studied in ULCOS ( Fig. 1 ), H 2 would be produced by water electrolysis using hydraulic or nuclear electricity. Iron ore would be reduced to direct reduced iron (DRI) by H 2 in a shaft furnace, and C-free DRI would be treated in an electric arc furnace (EAF) to produce steel.

The Basic Oxygen Steelmaking (BOS) Process – Consortium …

14/5/2011· The Basic Oxygen Steelmaking process differs from the EAF in that it is autogenous, or self-sufficient in energy. The primary raw materials for the BOP are 70-80% liquid hot metal from the blast furnace and the balance is steel scrap. These are charged into the Basic Oxygen Furnace (BOF) vessel. Oxygen (>99.5% pure) is “blown” into the BOF

The Use of Hydrogen in the Iron and Steel Industry
