Process optimisation model for FeMn and SiMn production

The combined process strategy requires a numerical model, helping to select the optimum process route for both process steps For this reason a FeMn/SiMn-process optimization model was developedImprove Ferromanganese Smelting Processes Using ,Keywords—Ferromanganese Production Indicators, Benchmarking Process, Benchmarking Matrix, Benchmarking Types I Improve Ferromanganese Smelting Processes Using Benchmarking Techniques (HC FeMn) And it consumed a lot of reductant per metal produced because the carbon source was both a source of power and a reductant Hence there was aTHEFERROMANGANESEPROCESS,considerable share ofthe total energy input to the process 1bere are several ways in which this energy may be supplied: 1) Ohmic energy production due to current flowing directly between the electrodes In FeSi production this is about 1% [1] In FeMn furnaces it is estimated to be smaller and ohmic energy will not be a significant contribution
