An introduction to ferromanganese
- In the 21st century, iron and steel is one of the most important products in secondary industries, because the consumption of these alloys in various manufacturing industries, such as tool manufacturing industries, household appliance parts, vital parts in cars such as valves or bearings, etc. It is very widely used. It is worth mentioning that among the important elements of iron and steel are ferroalloys. Ferroalloys are those iron alloys that, in addition to carbon, contain various elements such as manganese, etc., and are used in the iron and steel industry to improve the resistance of these alloys against corrosion and also to deal with the negative effects of sulfur during the process. Produced, used and used.
- It is worth noting that the number of ferroalloys is very large depending on whether their main purpose is to deoxidize iron. Among the large number of ferroalloys, today we are going to talk about one of the main ferroalloys produced in the metallurgy sector, that is ferromanganese alloy. Manganese is a metal that has a wide and essential use in everyday use and is found in nature in the form of oxides, hydroxides and sometimes in the form of carbonates and silicates. It is worth noting that this metal is the twelfth most abundant element in the earth’s crust! And its large reserves are found in Ukraine (24%), South Africa (22%) and Australia (16%). Brazil also has about 10% of the world’s manganese reserves.
The nature and application of ferromanganese
- Ferromanganese is an iron alloy obtained from carbothermal reduction (chemical reaction of minerals based on manganese oxides). Ferromanganese is also used in the process of making different types of iron and steel, as an agent for desulfurization, removal of nitrogen bubbles that may be created during production, and also to reduce the amount of iron oxide resulting from the production process. . It is good to know that this substance is a stable substance under normal conditions, although its contact with moisture leads to the production of acids and metal oxides, which can be harmful in long-term exposure. Also, although according to European regulations, this ferroalloy is not considered a dangerous element during transportation, however, precautions must be taken when moving this metal so that the dust from this ferroalloy does not spread, why The dust of this substance causes pollution and irritation of the respiratory tract.
How to produce ferromanganese
- Before describing the production process of this ferroalloy, it should be mentioned that ferromanganese was produced for the first time in 1872 with a purity of 37%. Today, for the production of ferromanganese, different under-charge furnaces or electric arc furnaces, as well as long furnaces and cylindrical melting furnaces are used. After the temperature of the furnace is increased to 2600 degrees Celsius, elements such as quartz, dolomite, manganese oxide rock and coke are added to the furnace, which ultimately leads to the production of ferromanganese. It is worth mentioning that high-carbon ferromanganese is made from the reaction of 28% manganese (poor manganese) with carbon in blast furnaces. While ferromanganese with medium carbon is decarburized with thermal silicon and thermal oxygen.
- Also, in the production of low-carbon ferromanganese, two methods of oxygen blowing in ferromanganese alloys or silicimetric reduction of manganese ore can be used. At the end of the production process of ferromanganese, the liquid ferromanganese alloy is discharged and transferred to casting machines for cooling, freezing and for commercialization according to the requirements of the consumer industry.
Ferromanganese types
- It is worth mentioning that due to the many applications of ferromanganese alloys, different types of ferromanganese can be produced for different applications. The most important types of ferromanganese in line with metallurgical purposes can be presented as follows:
- High carbon or standard ferromanganese alloys (Fe-Mn-AC).
- medium carbon ferromanganese alloys (Fe-Mn-MC);
- Low carbon ferromanganese alloys (Fe-Mn-BC)
- ferrosilico-manganese alloys (ferromanganese msds);
Applications of ferromanganese
- According to experts in the field of metallurgy, manganese is one of the important elements in increasing hardness, resistance and also reducing the brittleness of steel. For this reason, it has a very important role in the steel production process and in steel furnaces. In other words, the vast majority of ferromanganese alloys are consumed by steel and iron factories. Ferromanganese has interesting physical and chemical properties that help in the production of pig iron, alloys and special steels. This element acts as a desulfurizing, oxidizing (ore) and deoxidizing (metal) agent. In other words, manganese ferroalloys are used to separate excess oxygen and sulfur. Because the high concentration of sulfur in steel reduces the homogeneity and strength of the steel and eventually leads to its breakage. This is where ferromanganese leads to the improvement of steel strengthening through combination with sulfur and reducing its effect.
- Keep in mind that in most manufactured steels, the manganese content is about 0.05%, which reaches a maximum of 2%. More additions of this element make steel more resistant to wear and impact. However, the most use of ferromanganese in steel is for the production of rods and plates that are intended for use in civil engineering and heavy construction.
Buying ferromanganese
- Finally, it should be mentioned that in the group of ferroalloys (SIF/UFV), Ahan Madan is a well-known and prominent group in the production of high-quality ferroalloys such as ferromanganese. This group has guaranteed its customers in terms of the quality and resistant structure of its ferroalloys and believes that many customers will buy ferromanganese, ferrosilis, ferrosilicomanganese, sponge iron, etc. It has become one of the fixed customers of Ahan Madan and the process of buying them from this collection will be continuous. Among the qualitative characteristics of ferroalloys of this collection, we can mention the high percentage of ferromanganese absorption. In such a way that it absorbs excess oxygen as well as produced sulfur in a large amount and brings them into the slag.
- Therefore, do not hesitate to buy ferromanganese from this collection, and if you need to buy all kinds of ferroalloys, including ferromanganese, contact Ahan Mine experts. Also, if you encounter any problems during the ferromanganese purchase process, you can contact the support department. The consultants of this collection are ready to meet all your information needs, including the price of ferromanganese, around the clock. In the area of price, keep in mind that the experts of this collection always try to deliver very affordable ferroalloys to customers in addition to quality.
