Process For Production Of High Carbon Ferromanganese Alloy Using High Mno Slagand Coal Middling
Abstract: A process for producing 70 grade high-carbon ferromanganese alloy comprises steps of forming a blend mix of Manganese (Mn) ore feed in, in range of 64.2% – 64.5% (by wt.) and size fraction of 10 - 70 mm; Dolomite feed in, in the range of 7 - 8% (by wt.) and size fraction of 10 - 70 mm; Slag feed in, in the range of 9 - 10% (by wt.) and size fraction of 10 - 50 mm; Metallurgical coke feed in, in the range of 13.5-13.8% and size fraction of 6 - 25 mm; coal middling feed in, in the range of 4.5-4.8% (by wt.) and Size fraction of 3 - 20 mm; feeding the blend mix in a Submerged Arc Furnace (SAF) having process parameters Mn:Fe in the Mn ore = 4.1-4.2; Electrode penetration (from hearth of SAF) = 930-940 mm; and tapping the 70 grade high-carbon ferromanganese alloy in molten form.
