Ferro Manganese
Introduction
Ferro Manganese is made by smelting manganese ore as material in blast furnace or electric furnace which is 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 electric arc furnace-type system, called a submerged arc furnace. The oxides undergo carbothermal reduction in the furnaces, producing the ferro manganese. Ferromanganese is used as a deoxidizer for steel. Henry Bessemer invented the use of ferromanganese as a method of introducing manganese in controlled proportions during the production of steel. 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.
Application
Ferro Manganese is the deoxidizing agent which is usually used in steel making industry. It also has the performance that it can desulfurize and decrease the harmfulness of sulfur and improve strength of ductility of steels, additives to promote formation of Austenite of Stainless Steels. It 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.
