Ferroalloys

Introduction to Ferroalloys, Their Applications, and Factors Affecting Prices

If we want to refer to one of the most important materials required in various industries, we must mention Ferroalloys. These products, known in our country as Ferroalloys, are primarily used to enhance and strengthen properties such as tensile strength, improve shape modification, and create resistance against wear in steel.

How are Ferroalloys classified?

When purchasing Ferroalloys, they are usually classified into categories. Nowadays, these materials are divided into two main groups. The reason for this classification is related to the overall difference in their production, which also affects their prices.

The first and most widely classified category of Ferroalloys is the major category. These materials are produced in electric furnaces called electric arc furnaces. The production volume of these materials is very high and they are mainly favored by heavy industries.

Another category is considered special Ferroalloys. Unlike the previous type, these materials are only produced in highly specific furnaces, and their overall volume is usually much smaller. Although these products have fewer users, they are used for specific purposes such as purification and deoxidation.

How are Ferroalloys produced?

To produce these products, a blast furnace is required. In these furnaces, there is a high-intensity air flow, and on the other hand, a certain amount of ore is introduced. The high heat and a specific substance called coke accelerate the process of melting the ore.

In the next step, Ferroalloys will be prepared from the molten materials related to the respective ore. It is interesting to note that the production process of this product may take more than eight hours. However, these cases are only a part of the entire process of producing Ferroalloys. Naturally, each of these stages has different subsets that require specific conditions.

The relationship between Ferroalloys and iron ore

Some people ask about the relationship between Ferroalloys and iron ore. To answer this, it should be noted that the flux used inside the furnace for producing Ferroalloys is either iron ore or a type of iron ore. In fact, the absence of this material will prevent the production of high-quality Ferroalloys.

In the furnaces known as electric arc furnaces, the temperature required to melt these ores and produce Ferroalloys must exceed three thousand degrees Celsius, which is indeed a very high temperature. After the production process of Ferroalloys is completed, the remaining iron ore will not be usable. It should be mentioned that the overall quality of the iron ore used at this stage can also affect the final quality of the desired products.

What factors determine the consumption of ferroalloys?

In general, the consumption of ferroalloys depends on various factors, such as the type of steel to which you intend to add this material, the method of addition, steel slag, and the volume of the molten steel bath. Naturally, as the volume of the mentioned bath increases, the required amount of ferroalloy also increases.

Imbalance in the timing of adding ferroalloy to the existing steel solution leads to the production of unsuitable and very low-quality steel. Therefore, it is necessary to calculate the desired amount of ferroalloy accurately before carrying out this process.

Typically, in the production process of ferroalloy-containing steels today, this material is added in such a way that its amount in the ladle is higher than its amount in the tundish. However, this also depends on the type of steel, and in some cases, this ratio is reversed.

What are the different grades of ferroalloys that can be purchased?

Today, ferroalloys are available to users in various grades so that they can purchase them according to their needs. Naturally, the existence of such diversity allows users to choose the most suitable product when buying ferroalloy.

Among the most important grades of this product, we can mention items such as ferro niobium, ferro boron, ferro vanadium, ferro molybdenum, ferro titanium, ferro chrome, and more. These options are only part of the grades of ferroalloy, and there are other options that users can purchase.

The main factors affecting the price of ferroalloys

We cannot talk about the factors affecting the price of ferroalloys, but we should mention the overall quality of raw materials and iron ore. It should be noted that the higher the quality and overall quality of the raw materials used to produce ferroalloys, the higher the price of the final products will be.

Another important factor that affects the final price of ferroalloys is the exchange rate. Some of the raw materials needed to produce these products are imported, and for this reason, an increase or decrease in the exchange rate can have an impact on their price.

Ferrosilicomanganese

Today, alloys are materials that have contributed to the advancement of industries and technological growth. Various materials are used to produce alloys, but one of the most important ones is ferroalloys. Ferrosilicomanganese, which we will focus on in this article, is one of the important ferroalloys used in the steel industry. Stay with us to learn more about this material.

What is Ferrosilicomanganese?

Ferrosilicomanganese (FeSiMn) belongs to the category of ferroalloys produced from silicon and manganese. This ferroalloy is highly resistant to heat and temperature due to its high manganese content, making it suitable for the construction of various types of furnaces and other equipment. This ferroalloy is particularly suitable for the production of steels with low carbon content. The presence of silicon manganese helps retain excess silicon in the production process of various materials, resulting in the strength and resistance of products against various chemical compounds. Iron and phosphorus are other constituents of this ferroalloy.

However, it should be noted that there is another type of this material called low-carbon ferrosilicomanganese, which is produced from materials such as manganese, silicon, iron, phosphorus, carbon, and sulfur. Many forms of this material are used in various industries without any contamination.

Ferroalloys

As you have seen in this text, the term “ferroalloy” is repeated alongside this material, so it is better to familiarize yourself with the concept of ferroalloy before explaining its various applications.

Ferroalloy, also known as “hardter” or “amijan,” is widely used in various petrochemical and alloying industries due to its status as a primary material in many products. It has a high weight, and iron is one of the main materials used to produce alloys.

This material speeds up the melting process and production, making it used in the construction of various furnaces and electric motors.

Applications of Ferrosilicomanganese

One of the uses of ferrosilicomanganese is in the steel industry, where it is extensively utilized. Here are a few important applications of ferrosilicomanganese:

• Reduction of carbon solubility in various steels and alloys
• Deoxidation in alloys
• Reduction of impurities in materials such as sulfur, phosphorus, and nitrogen
• Enhancement of strength and power in various steels
• Suitable substitute for ferrosilicon and ferromanganese

It should be noted that silicon and manganese play a significant role in alloy production as they reduce oxidation in steel and eliminate excess sulfur in alloys. Silicon is the best material to reduce the oxidation of iron. Additionally, manganese also acts similarly to silicon and is one of the most important types of alloys used in steelmaking.

Another application of ferrosilicomanganese is in alloying for producing steel and deoxidation. Moreover, it can be used for steel production with low carbon content. Note that ferrosilicomanganese with a silicon content greater than 70% is used for producing stainless steels.

Ferrosilicomanganese acts as a very strong deoxidizer when it contains a significant amount of silicon, enhancing the mechanical properties of steel. Generally, the use of this material in industries is primarily focused on improving the mechanical properties of steels through the addition of alloying elements and the removal of elements such as sulfur and oxygen. The primary alloying elements increase the strength and heat resistance of steels.

Production Process of Ferrosilicomanganese

To produce ferroalloys, mineral ores are utilized. These ores need to be first oxidized and then used for the production of alloys. However, the most important production methods for this practical material are as follows:

1. Production using carbonaceous materials by adding electrical energy in arc furnaces.
2. Production using metals such as aluminum and silicon through heat reduction.

As mentioned, ferromanganese must be produced from mineral ores in electric arc furnaces or tall furnaces that can withstand high heat intensity. Ferrosilicomanganese needs to be produced with a moderate carbon content through the combination and refining with manganese, so that it acquires not only strength but also antioxidation properties. Furnaces play a crucial role in the production of this material because, after the combination, all the materials must be heated at high temperatures and remain resistant due to the presence of a substance called silicon. Many engineers use sand or quartz to produce silicon and then mix it with carbon, subjecting it to heat again. After the combination and addition of sand and carbon in the final stage, pure iron is added to the compounds, and ferrosilicomanganese is produced in the ferrosilicomanganese furnace.
