Product Description
Ferromanganese Furnace: Equipment and Technical Parameters
1. Equipment Overview
Ferromanganese furnaces are divided into two main types: Submerged Arc Reduction Furnace (for high-carbon ferromanganese HC FeMn) and Refining Electric Arc Furnace (for medium/low-carbon ferromanganese MC/LC FeMn).
- High-carbon ferromanganese submerged arc furnace (SAF): Adopts three Söderberg self-baking electrodes submerged in burden, relies on arc & resistance heating for carbothermic reduction of manganese ore, closed furnace design for CO furnace gas recovery, large capacity for continuous mass production.
- Medium & low-carbon ferromanganese refining furnace: Tilting AC/DC arc furnace with graphite electrodes, silicothermic decarburization refining to produce low-carbon high-purity ferromanganese for high-grade steelmaking.
