Brief Introduction to Ferro Manganese

Ferro manganese (FeMn) is an alloy of iron and manganese usually containing about 80% manganese. It is mainly used as a deoxidiser and counters bad effects of sulphur in metals. It is made by heating a mixture of the oxides MnO2 and Fe2O3 with carbon in a blast furnace or electric arc furnace type system called a submersible furnace. The oxide undergoes carbothermal reduction in the furnace to produce ferro manganese. FeMn improves hot working properties and impacts properties such as increased strength, hardness toughness and hardenability.

Main Grades of Ferro Manganese

There are several grades of Fe-Mn which are divided into many groups. The three main groups are high carbon Fe-Mn (HC Fe-Mn), medium carbon Fe-Mn (MC Fe-Mn), and low carbon Fe-Mn (LC Fe-Mn). By adding the Mn as MC Fe-Mn or LC Fe-Mn instead of HC Fe-Mn, around 80 % to 93 % less C is added to the steel. Nitrided MC Fe-Mn contains a minimum of 4 % of nitrogen (N2).

Properties of Ferro Manganese

Physical Properties
Ferro manganese is a solid block material that is nearly odorless when dry and often has a silvery metallic surface. During storage, the surface is often covered with a black oxide layer. It is generally free of extraneous contaminants such as slag and non-metallic inclusions. It is usually supplied in the form of crushed and screened material. The density of Fe-Mn ranges from 7.3 to 7.4 grams per cubic centimeter. Its bulk density is approximately 4 tons per cubic meter. Depending on the size of the material, the angle of repose varies from 40 to 60 degrees.

Chemical Properties
The chemical name of ferro manganese is FeMn. It has a minimum manganese content of 65% and a maximum manganese content of 95%. The three main categories of this metal alloy commonly used are HC Fe-Mn, MC Fe-Mn and LC Fe-Mn. Iron and manganese are flammable and insoluble in water. Non-reactive under normal conditions of use, storage and transportation. Fe-Mn has a melting range of 1050 degrees Celsius to 1260 degrees Celsius, depending on its chemical specifications.

Advantages of Ferro Manganese in Steelmaking

The addition of this Ferro Manganese alloy to steel brings about several crucial advantages, including:

Ncreased Strength And Toughness

Ferro Manganese significantly increases the tensile strength of steel, making it ideal for constructing sturdy buildings, bridges, and other infrastructure projects. The toughness of steel is also improved, enabling it to withstand heavy loads and harsh environments.

Corrosion Resistance

Steel infused with Ferro Manganese exhibits excellent corrosion resistance, making it ideal for applications in marine environments or structures exposed to corrosive substances.

Deoxidizing Agent

Ferro Manganese serves as a powerful deoxidizing agent in steelmaking. It removes impurities such as oxygen and sulfur, enhancing the overall purity of the steel and improving its mechanical properties.

Enhance Workability

The addition of Ferro Manganese to steel results in improved workability and weldability. This makes it easier for manufacturers to shape the steel into various forms for different applicat

Types of Ferro Manganese

There are seven types of iron and manganese, as follows:

LC Fe-Mn

It is used for steels with very low content of C. In this type, C content is ranging from 0.07 % to 0.75 %. LC Fe-Mn is suitable for use in the production of 18-8 chromium-nickel (Cr-Ni) stainless steels in which a C content well below 0.10 % is required.

MC Fe-Mn

This alloy contains 80 % to 85 % of Mn, 1.25 % to 1.50 % of C and 1.50 % maximum of Si. It is commonly used in making low C Mn steels. It is also used in the production of Hadfield Mn steel, when large amounts of return scrap are being melted.

HC Fe-Mn

This alloy contains 75 % to 80 % of Mn, 7.5 % of C and 1.2 % of Si. It is normally used in the iron and steel industry as deoxidizer, fixer of S and alloying agent.

Low Fe Fe-Mn

It is used for numerous applications in the Ni, aluminum (Al), and copper (Cu) industries where there is necessity of high Mn and low Fe and where low C content of pure Mn metal is not necessary. It contains 85 % to 90 % of Mn, 2 % of Fe, 3 % of Si, and 7 % of C.

Machining Screw (MS) Grade Fe-Mn

It contains 80 % to 85 % of Mn, 0.35 % of Si, and 1.25 % to 1.50 % C. This low Si Fe-Mn alloy is developed to add during production of free machining screw steels.

Drawing Quality (DQ) Grade Fe-Mn

It contains 86 % of Mn, 0.45 % of C, 0.40 % of Si, and 0.17 % of P. This is refined Mn product which is used as additive to steels for DQ steel sheets where both low Si and low C contents are desirable. This alloy is also used as addition agent for stainless and constructional alloy steels.

Exothermic Grade Fe-Mn

Several grades of Fe-Mn briquettes are sold in the market which contains constituents that cause an exothermic reaction when added to a steel bath, e.g. barium (Ba) salts. This special material is used for ladle additions of Mn to prevent chilling of the ladle contents.

Several Key Steps in the Ferro Manganese Production Process

The production of ferro manganese involves several key steps to ensure the high quality and consistent performance of the alloy.

Mining and Extraction

Manganese ore is mined and then processed to extract manganese, the main ingredient in the production of ferro manganese.

Smelting

The extracted manganese is smelted in a blast furnace along with iron ore and coke. The high temperature in the furnace is beneficial to the reduction of manganese and iron oxides.

Alloying Process

The smelted ferro manganese undergoes an alloying process where carbon is added to obtain the required manganese and iron content.

Cooling and Solidification

The molten ferro manganese is cooled and solidified into different forms such as ingots or pellets, ready for further industrial applications.
