Ferro – Manganese Alloys

Manganese Ferro Alloys consist of various grades of Ferro Manganese and Silico Manganese.

Manganese Ferro Alloys are mainly manufactured by carbothermic reduction of manganese ores containing both iron and manganese oxides in submerged arc electric furnaces. The slags produced during the process contain significant amounts of manganese oxide. Manganese Oxide (MnO) and these slags can be reprocessed to Ferro Silico Manganese (popularly called Silico Manganese) and then to refined or Low-carbon (LC – Fe Mn) Ferro Manganese or even to Manganese metal.

High-carbon Ferro Manganese, generally with 70–80% Mn and 6–8% C, is a deoxidizing agent in steel making and an important alloying element. It has also the property of controlling the harmful effect of sulfur.

Silico Manganese is generally made in two grades, containing 60–65% Manganese (Mn) but with ideally either 14–15% Si or 15–19% Si. These alloys are preferred by steelmakers who require to add manganese and silicon simultaneously for deoxidation purposes. Silico-Manganese is used either as a substitute for ferro manganese and ferro silicon in steel making or as a raw material for the production of medium and LC ferro manganese and industrial manganese metal. The product of deoxidation is a fluid manganese silicate slag.

FURMATS offer Ferro Mangese (High Carbon or HC Ferro Manganese, Medium Carbon or MC Ferro Manganese & Low Carbon or LC Ferro Manganese apart from Silico Manganese (regular grade and Medium Carbon Silico Manganese) for both Domestic as well as Export demands

Ferro Manganese with Low Phos content of upto .1% Max is also available for specific customer demands
