Ferromanganese, derived from the ancient steel-making process, is unique in the field of industrial metals with its unique composition and properties. Ferromanganese has been widely used in various industrial productions since the 19th century. With the advancement of science and technology, the use and demand of ferromanganese are also growing, becoming an indispensable part of modern industry.
1.Ferromanganese specifications and classification
Ferromanganese is mainly divided into two categories: high carbon ferromanganese and low carbon ferromanganese. High carbon ferromanganese contains more than 70% manganese and has high strength and hardness. It is mainly used in the cast iron, steelmaking and forging industries. Low-carbon ferromanganese contains less than 60% manganese and has good toughness, plasticity and wear resistance. It is widely used in the production of structural parts, tools and special steels.
In terms of specifications, ferromanganese is mainly classified according to its manganese content, carbon content, and the content of impurities such as phosphorus and sulfur. Common specifications include Mn55C2.0, Mn55C3.0, Mn60C2.0, etc. These specifications represent different chemical compositions and physical properties. In addition, depending on the use, there are also special specifications of ferromanganese such as low phosphorus and low sulfur.
2.Ferromanganese production process
The production of ferromanganese is mainly achieved through high-temperature smelting, refining outside the furnace, continuous casting and rolling and other processes. During the production process, key parameters such as raw material quality, melting temperature, and pouring speed need to be strictly controlled to ensure product quality. In addition, for special specifications of ferromanganese, special smelting methods need to be used, such as vacuum smelting, electroslag remelting, etc.
3.Characteristics of ferromanganese
High strength and hardness: High carbon ferromanganese has high strength and hardness, high tensile strength and yield point, making it excellent in the cast iron, steelmaking and forging industries.
Good wear resistance: Low carbon ferromanganese has good wear resistance and is often used to manufacture wear-resistant castings and wear-resistant materials, such as excavator tracks, crusher tooth plates, etc.
Excellent toughness: Low carbon ferromanganese is not easy to break under impact load, has good toughness, and is suitable for manufacturing parts and tools that withstand impact.
Excellent process performance: Ferromanganese has good casting performance, welding performance and cutting performance, making it have high production efficiency and yield in the manufacturing process.
4.Application of ferromanganese
Steel industry: As one of the main raw materials of steel, ferromanganese plays an important role in improving the strength, hardness and corrosion resistance of steel. Especially in the production of high-strength low-alloy steel, ferromanganese is used more widely.
Non-ferrous metal industry: In the smelting of non-ferrous metals such as copper and aluminum, ferromanganese is used as an additive to improve the properties of the alloy and improve its strength, hardness, corrosion resistance and processing performance.
Other industries: In addition to the above-mentioned industries, ferromanganese is also widely used in aerospace, automobile manufacturing, construction and other fields. For example, in automobile manufacturing, steel plates made of low-carbon ferromanganese have better impact resistance and corrosion resistance.
With the advancement of science and technology and the development of industry, the demand for ferromanganese will continue to grow. In the future, in order to meet various complex and harsh use environments, the research and development and production of ferromanganese will pay more attention to the improvement of properties such as high strength, high toughness, and high corrosion resistance.
When selecting ferromanganese specifications, the selection should be based on actual application scenarios and performance requirements. For example, for scenes that require high strength and hardness, high carbon ferromanganese should be selected; for scenes that require good wear resistance and toughness, low carbon ferromanganese should be selected. In addition, factors such as impurity content, production process and cost should also be considered. You can choose ZHENXIN ferroalloy.
