What is Ferro Silicon Manganese Used For?

Ferro silico manganese is mainly smelted by submerged arc furnaces, which can be operated continuously. In addition, blast furnaces can also be used to smelt ferromanganese, although blast furnace smelting mainly produces high-carbon ferromanganese. Refining furnaces are used for subsequent refining processes such as decarburization after blast furnace smelting. The production scale can range from large, medium to small SAF.

Oil-fired furnaces are an industrial equipment used to smelt various ferroalloys (including ferrosilicomanganese, ferrosilicon, ferromanganese, etc.). 

The Advantages of Ferrosilicomanganese Submerged Arc Furnace

• High efficiency: The submerged arc furnaces can effectively reduce raw materials (manganese ore, silica, etc.) to ferroalloys.

• High energy consumption: SAF smelting furnaces are high-energy consumption equipment, and electricity costs account for a large proportion.

• Widely applicable: In addition to ferrosilicomanganese, it can also smelt other ferroalloys.

As an important ferroalloy, ferrosilicomanganese is mainly used for deoxidation and alloying in the process of steel smelting. Let's learn about its specific uses.

Uses of Ferro Silico Manganese

1. Deoxidizer & alloying agent in steelmaking:

Both silicon and manganese have strong affinity with oxygen, and produce deoxidized products (MnSiO3, MnSiO4) in molten steel, which have the advantages of low melting point, large particles, and easy floating. They can effectively remove oxygen from molten steel and improve the quality of steel. At the same time, silicon and manganese are also alloying elements of steel, which can improve the strength, wear resistance, thermal strength and corrosion resistance of steel. 

2. Raw materials for the production of medium & low carbon ferromanganese:

Ferro silicon manganese alloy can be used as a semi-finished product for the production of medium and low carbon ferromanganeses and electrosilicon thermal method metal manganeses. 

3. Alloying agent for the production of special steel:

Ferrosilicon manganese can be used to produce special steels such as high-temperature alloy steel and wear-resistant steel to improve their thermal strength and wear resistance. 

4. Other uses:

In the fields of chemical industry, metallurgy, etc., ferrosilicon manganese can also be used as a reducing agent.

From the above content, it can be seen that ferrosilicomanganese is mainly used as a deoxidizer and alloying agent in the steelmaking process to eliminate excess oxygen and sulfur in molten steel and improve the quality and performance of steel.

It contains manganese, silicon and iron. During the SAF smelting process, silicon can combine with oxygen in steel to form solid oxides, thereby reducing the harm of oxygen to steel and improving the quality of steel.

In addition to steelmaking, silicon is also used to smelt magnesium metal. Molten iron is decarbonized by blowing oxygen or adding oxidants to remove harmful impurities such as phosphorus and sulfur. 

In addition, ferro silico manganese can also be used as the main raw material for the production of medium and low carbon ferromanganese.
