Standard grade ferromanganese can be produced either in a blast or electric furnace. High carbon ferromanganese can be produced by 3 different processes: blast furnace, discard slagelectric furnace, and highmanganese slagelectric furnace. During high carbon ferromanganese production, parameters such as temperature, time and, charge basicity affect the

1.10.4.6.1 Production of Ferromanganese in Electric Arc Furnaces The majority of producers of ferromanganese in the world use submerged arc electric furnaces. Although electric furnaces have lower capacities than blast furnaces they have the advantage that the heat requirement is provided by electricity, and coke and coal are added to the feed only as reductants

MEDIUM / LOW CARBON FERROMANGANESE. MC / LCFeMn . MN ALLOYS . Mn alloys are mostly used in steelmaking and foundry activities. Some 30 % of the manganese used today in steelmaking is still used for its properties as a deoxidant and a sulphide former. In this last case it combines with sulphur avoiding the formation of sulphides,iron which

The production of silicoman-ganese alloys is not further discussed in this paper, though the trends obtained in energy reduction for ferromanganese alloys will also apply for silicomanganese production. The raw materials used for ferromanganese production are manganese ores, fluxes and carbon. Also typically re-melt is added
