1. Deoxidizer and desulfurizer
Ferromanganese is an indispensable deoxidizer in the steelmaking industry. Manganese can react with iron oxide to form manganate, which plays the role of oxygen remover, reduces the oxygen content in the steel, reduces the oxide content in the steel, and improves the purity of the steel.
At the same time, ferromanganese is also an effective desulfurizer. The binding force of manganese and sulfur is greater than that of iron and sulfur, and manganese sulfide with a high melting point can be generated when added to molten steel, which can be converted into slag for discharge, effectively reducing the content of harmful elements in steel and improving the quality of steel.
2. Improve the hardness and strength of steel
The manganese element in ferromanganese is able to form MnS with the carbon in the steel, which increases the hardness of the steel and enhances the strength and wear resistance of the steel.
3. Improve the toughness and cold brittleness of steel
Manganese can combine with sulfur in steel to form MnS with low melting point, preventing sulfur from being concentrated at grain boundaries, thereby reducing the brittleness of steel and improving the toughness of steel.
4. Adjust the grain size
The addition of an appropriate amount of ferromanganese can adjust the grain size of the steel and affect the structure and properties of the steel. Smaller grain sizes can improve the strength and plasticity of steel.
5. Alloying elements
As an alloy additive, ferromanganese and iron contain manganese and iron elements that can effectively increase the strength, hardness and corrosion resistance of steel.
6. Antioxidant effect
Ferro-manganese can reduce the oxidation reaction of steel at high temperatures, reduce the oxidation loss of steel materials, and prolong the service life.
In the steelmaking process, the choice of ferromanganese alloys is mainly based on their carbon content and specific use.
Carbon content: between 0.15% and 0.7%.
Features: Low-carbon ferromanganese is mainly used as a deoxidizer and alloy additive in steelmaking. Due to its lower carbon content, it helps to reduce the carbon content in the steel, which improves the properties of the steel.
Application: Widely used in the iron and steel metallurgical industry, especially where the carbon content of steel needs to be controlled.
Carbon content: between 0.7% and 2.0%.
Features: Medium carbon ferromanganese is a widely used alloy material, because it contains high manganese content and low sulfur content, it can effectively improve the hardness, strength and toughness of steel.
Application: Medium carbon ferromanganese is often used as an additive in steel production for the production of various types of steel, such as structural steel, wear-resistant steel, weathering steel, etc. It is widely used in construction, bridges, automobiles, machinery and other industries. In addition, medium carbon ferromanganese also plays a certain role in the field of environmental protection and can be used as a wastewater treatment agent.
Carbon content: between 2.0% and 8.0%.
Features: High carbon ferromanganese has a high melting point and oxidation resistance, and is an important deoxidizer and alloy additive. It can effectively reduce the content of other impurity elements and improve the mechanical properties and corrosion resistance of steel products.
Application: High-carbon ferromanganese is widely used in iron and steel metallurgy, casting, electronics industry and other fields. In the ferrous metallurgical industry, high-carbon ferromanganese is widely used as a deoxidizer and silicon-manganese alloy additive to improve the quality and performance of steel.
Main ingredients: manganese, iron, silicon
Features: Ferro-silicon-manganese is a commonly used deoxidizer and alloying agent, which can effectively reduce the oxygen content in molten steel and improve the quality of steel. It can also increase the hardness, toughness, wear resistance and other properties of steel.

Introduction to the Uses and Application Fields of Chromium1, ferrochrome in the steelmaking process has to increase the antioxidant steel: in the steelmaking process into the ferrochrome can increase the antioxidant steel, ferrochrome in the chromium can protect the steel, so that the oxidation rate slows down to increase the antioxidant steel, with the advantages of enhancing the service life of the steel;
2, put the proportion of ferrochrome in steel water has to enhance the corrosion resistance of steel: in the process of steelmaking according to the content of elements in steel water in proportion to a certain amount of ferrochrome can enhance the corrosion resistance of steel, ferrochrome in the chromium can be attached to the surface of the steel to provide a layer of insulation and thus play a corrosion-resistant ability of the advantages.
3, ferrochrome has to enhance the hardness of steel and abrasion resistance: now the steelmaking process are generally put into the ferrochrome, the main reason is that ferrochrome can enhance the hardness of steel and abrasion resistance, ferrochrome chromium in the oxygen because of the element is not easy to combine, so you can enhance the steel oxidation resistance, in addition to ferrochrome can also be purified of impurities in steel to enhance the hardness of steel.- What is silicon carbide and what is its function?Silicon carbide, an inorganic substance with the chemical formula SiC, is smelted at high temperatures in resistance furnaces using raw materials such as quartz sand, petroleum coke (or coal coke), and wood chips (table salt is added to produce green silicon carbide). Silicon carbide is a semiconductor that exists in nature in the form of the extremely rare mineral moissanite. It has been mass-produced as powder and crystals since 1893, and is used as an abrasive and so on. Among the non-oxide high-tech refractory raw materials such as C, N and B, silicon carbide is one of the most widely and economically used, and can be referred to as golden steel sand or refractory sand. Chinese industrial production of silicon carbide is divided into two kinds of black silicon carbide and green silicon carbide, both are hexagonal crystals.
What is silicon iron? What are the uses of silicon iron?Silicon iron is an indispensable deoxidizer in the steelmaking industry. In steel, silicon iron is used for precipitation deoxidation and diffusion deoxidation. Pig iron is also used as an alloying agent in steelmaking. Adding a certain amount of silicon to the steel can significantly enhance its strength, hardness, and elasticity, increase its magnetic permeability, and reduce the magnetic hysteresis loss of transformer steel. Generally, the silicon content in steel is 0.15% - 0.35%, in structural steel it is 0.40% - 1.75%, in tool steel it is 0.30% - 1.80%, in spring steel it is 0.40% - 2.80%, in stainless and acid-resistant steel it is 3.40% - 4.00%, in heat-resistant steel it is 1.00% - 3.00%, and in silicon steel it is 2% - 3% or higher.
High-silicon silicon iron or silicon-based alloys are used in the iron alloy industry as reducing agents for the production of low-carbon iron alloys. Adding silicon iron to cast iron can be used as a nucleating agent for ductile iron, and can prevent the formation of carbides, promote the precipitation and spheroidization of graphite, and improve the performance of cast iron.
In addition, silicon iron powder can be used as a suspension phase in the mineral processing industry, and as a coating for welding rods in the welding rod manufacturing industry; high-silicon silicon iron can be used in the electrical industry to prepare pure silicon for semiconductors, and in the chemical industry to manufacture silicone and other substances.
In the steelmaking industry, approximately 3 - 5 kg of 75% silicon iron is consumed for every ton of steel produced.
Melting point: 75FeSi is 1300℃
Silicon iron contains small amounts of metal compounds of phosphorus, such as calcium phosphide, etc. When exposed to moisture during transportation by vehicles or storage in warehouses, phosphine can be released, causing poisoning to people in the warehouse or surrounding areas. Severe phosphine poisoning can be fatal.
