Ferromanganese Powder

Description  of Ferromanganese alloy

Ferromanganese, a ferroalloy with high content of manganese,  is made by heating a mixture of the oxides MnO2 and Fe2O3 ,with carbon, usually as coal and coke, in either a blast furnace or an electirc arc furnace-type  system, called a submerged arc furnace.

The oxides undergo carbothermal reduction in the furnaces, producing the ferromanganese.

The advantage of combining powdered iron oxide and manganese oxide together is the lower melting point of the combined alloy compared to pure manganese oxide.

The ten grades covered under this specification includes

High ferromanganese

Medium ferromanganese

Low-carbon ferromanganese

A similar material is a pig iron with high content of manganese, is called spiegeleisen

UsesIn the steel that is used for deoxidizing agent and alloying agent, is the largest amount of iron alloy.

Application of Ferromanganese alloy

1. Used for deoxidizing agent and alloying agent in the steel fieldis, it is the largest amount of iron alloy

2. It also has the performance that it can desulfurize and decrease the harmfulness of sulfur.

So when we make steel and cast iron, we always need certain account of manganese.

3. It is also used as an important kind of alloying constituent to be widely applied to alloy steel,

such as structural steel, tool steel, stainless and heat-resistant steel and abrasion-resistant steel.
