pdf process optimisation model for femn and simn production

Feb 08, 2016 Approximately 90 % of total manganese production is in the form of high-carbon ferromanganese (HC FeMn), silicomanganese (SiMn), and refined ferromanganese (Ref. FeMn) alloys utilized in the production of steel and stainless steel for sulfur-fixing and deoxidizing and as an alloying element to improve strength and hardness (Olsen et al. 2007). Jun 11, 2021 In production of FeMn alloys, which are mostly used for alloying steel, Mn-containing ores are reduced by C materials in furnaces at high temperatures to liquid FeMn alloy. A by-product of this process is a large amount of slag formed by oxides present in the raw materials, typically 600 to 800 kg per tonne of FeMn.

Duplex Process is Considered More Sustainable than the Commercial Production Process. The commercial production of FeMn is through the carbothermic smelting-reduction of manganese (Mn) ores using blast furnace (BF) and submerged arc furnace (SAF) technologies. Metallurgical coke is the main solid carbon reductant that is used in SAF technology.
