Production of Ferro- Manganese IspatGuru

Jun 19, 2018· The MOR process has many advantages over the silico-thermic process which includes lower energy consumption, lower capital investment, lower production cost, and greater flexibility. The main disadvantage of the process is that its use is limited to production of medium C Fe-Mn because the C content cannot be reduced to below 1.3 %.

7.7.1.2 Decarburization of High Carbon Ferromanganese. In this process, HC FeMn alloy (~7% C, <1% Si) is decarburized by blowing the metal in its liquid state with oxygen gas or with oxygen-argon mixtures. This manganese oxygen refining (MOR) process is in many ways similar to the basic oxygen steel process (BOF) where liquid cast iron is

Ferromanganese Wikipedia

Ferromanganese, a ferroalloy with high content of manganese, is made by heating a mixture of the oxides MnO 2 and Fe 2 O 3, with carbon, usually as coal and coke, in either a blast furnace or an electric arc furnace-type system, called a submerged arc furnace.The oxides undergo carbothermal reduction in the furnaces, producing the ferromanganese. . Ferromanganese is used as a deoxidi
