Slag Formation during Reduction of Iron Oxide Using Hydrogen Plasma Smelting Reduction. [PDF]
Materials (Basel), 2020 Replacing carbon by hydrogen is a huge step towards reducing CO2 emissions in the iron- and steel-making industry. The reduction of iron oxides using hydrogen plasma smelting reduction as an alternative to conventional steel-making routes has been studied at Montanuniversitaet Leoben, Austria. The aim of this work was to study the slag formation during
