Ferromanganese

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 furnaceThe oxides undergo carbothermal reduction in the furnaces producing the ferromanganese Ferromanganese is used as a deoxidi...

Ferro Manganese Nitride

In Germany it was suggested that the ground ferromanganese or manganese be nitridated in a rotary kiln The process is similar to the production of lime nitrogen in the rotary kiln at 923-1273K The operation uses only a small nitrogen overpressure In order for the ferromanganese particles to truly permeate nitrogen it is important that...
