manganese ferroalloys processes

Economic Impact Analysis (EIA) for the Manganese

Ferroalloys within the scope of this source category are produced using submerged electric arc furnaces, which are furnaces in which the electrodes are submerged into the charge. The submerged arc process is a reduction smelting operation. The reactants consist of metallic ores (ferrous oxides, silicon oxides, manganese oxides,

Ferroalloys an overview ScienceDirect Topics

Lauri Holappa, in Handbook of Ferroalloys, 2013. Abstract. The word ferroalloy refers to an alloy of iron containing a significant proportion of one or more other elements like silicon, manganese, chromium, aluminum, or titanium. The main applications of ferroalloys occur in the steelmaking process. They are added to steel to improve properties like strength, ductility, and fatigue or

Silico Manganese Production. Ferroalloys Industry

Silico manganese is an alloy with 60% to 68% manganese, 14% to 21% silicon, and 5% to 2.5% carbon. It is produced by smelting of slag from high-carbon Ferro Manganese or of Manganese ore with coke and a quartz flux in a submerged electric arc furnace. The process requires power consumption of about 3,800 to 4,800 kilowatt-hours per tonne.

Manganese Ferroalloys Technology ScienceDirect

Jan 01, 2013· In many manganese ferroalloys smelting and agglomeration processes, basic fluxes like lime or dolomite are often added. This shifts phase equilibria and leads to new, important phase fields. Examples of calculated phase and liquidus relations for the MnO-SiO 2 -CaO-Al 2 O 3 (weight ratio Al 2 O 3 /SiO 2 = 0.425) system are shown in Figure 7.12 .
