hydrogen plasma processing of iron ore

Project 31

Starting with experiments with molecular hydrogen, work was also continued with hydrogen plasma In cooperation with the Montanuniversität Leoben and voestalpine, K1-MET has set itself the task of advancing the process for the reduction of iron ore by plasma smelting with hydrogen and argon...

The Way to a Carbon free Steelmaking

The gas mixture can be provided by different ratios of plasma gas to hydrogen which is one of the main parameters influencing the hydrogen utilization and efficiency of the process Additionally, the continuous feeding of the fine iron ore and additives is being done through the hollow electrode...
