Ferro Manganese

Ferro Manganese

Ferro Manganese is a type of ferroalloy that contains high amounts of manganese and iron. Ferro Manganese is used as a deoxidizer and an alloying agent for steel. It improves the strength, hardness, toughness, and wear resistance of steel and also prevents the steel from becoming brittle by removing Sulphur. There are different grades of Ferro Manganese, depending on the Manganese and carbon content. The main grades are high-carbon Ferro Manganese (HC Fe-Mn), medium carbon Ferro Manganese (MC Fe-Mn), and low-carbon Ferro manganese (LC Fe-Mn).

Advantages of using Ferro Manganese in Steelmaking

It reduces the amount of oxygen in the molten steel, which prevents the formation of oxides and improves the quality and yield of steel.
It increases the hardenability of steel, which means that the steel can be hardened by heat treatment to a greater depth and degree.
It enhances the resistance of steel to abrasion, corrosion, and impact.
It modifies the microstructure and mechanical properties of steel, such as tensile strength, ductility, and toughness.
It lowers the melting point and improves the fluidity of steel, which facilitates casting and welding operations.

How much Ferro Manganese is needed for steelmaking?

The amount of Ferro Manganese needed for steelmaking depends on the grade of steel and the desired properties. the typical consumption of Ferro Manganese per ton of steel is 6 to 9 kg for carbon steel, 45 to 90 kg for high strength low alloy steel, and 9 to 18 kg for stainless steel. However, these values may vary depending on the specific composition and process of steelmaking.

Production of Ferro Manganese

Ferro manganese is produced by the carbothermic reduction of ores containing manganese and iron oxides with carbon, usually as coal and coke. This process can be carried out in either a blast furnace or an electric arc furnace-type system, called a submerged arc furnace.

In the blast furnace, the ore, flux, and coke are charged from the top and hot air is blown from the bottom. The reduction of manganese and iron oxides occurs in the lower part of the furnace, producing liquid slag and metal. The metal is tapped periodically and refined further.

In the submerged arc furnace, the ore, flux, and coke are fed through a hopper and preheated by CO gas generated from the coke bed zone. The main reduction of manganese and iron oxides occurs in the coke bed zone, where electric current passes through electrodes and creates heat. The liquid slag and

metal are collected at the bottom of the furnace and tapped separately.
