Medium-Carbon Ferro Manganese
Overview & Characteristics
Medium-carbon ferromanganese is a ferroalloy composed of manganese, iron, and carbon. It typically contains 75%-82% manganese, with its carbon content strictly controlled within the critical range of 1.0%-2.0%. Its appearance is characterized by silver-gray lumps. It is mainly suitable for medium-low carbon steel smelting, integrating deoxidation and alloying functions, and serves as a core auxiliary for automotive steel and construction machinery steel.

Production Process
Using high-carbon ferromanganese (Mn≥75%) as raw material, decarburization is conducted via converter or electric furnace refining: at 1350-1500℃, carbon is removed by silicothermic method or oxygen oxidation to control final carbon at 0.5%-2.0%; after cooling, it is crushed into 20-50mm lumps, tested by ICP to meet GB/T 4701.2-2009, and delivered with CoA report.
