Electrolytic Manganese

1. The smelting of copper alloy requires a large amount of manganese. Moreover, the ingredients are easy to control precisely.

2. Electrolytic manganese metal is widely used in manganese-copper alloys, manganese-aluminum alloys, and 200 series stainless steel. Manganese can improve the hardness, strength, toughness, wear resistance, and corrosion resistance of metal materials.

3. Due to its high purity and low impurities, electrolytic manganese metal has been successfully widely used in various fields such as steel smelting, non-ferrous metallurgy, electronic technology, chemical industry, environmental protection, food hygiene, welding rod industry, and aerospace industry.

The main functions of manganese ingots in steelmaking are deoxidation, desulfurization, and alloying elements.

(1) Used as deoxidizer

Steel has strict requirements on oxygen content, generally no more than 0.02%, or even more stringent. Therefore, excess oxygen is removed during the steelmaking process. Manganese is a reactive metal and its chemical properties are more reactive than iron. When manganese is added to molten steel, manganese will react with ferrous oxide to form oxidized slag that is insoluble in molten steel. The oxidized slag floats on the surface of molten steel and reduces the oxygen content in the steel.

(2) Used as desulfurized

Sulfur is present in molten steel in the form of iron sulfide. The high sulfur content in steel can easily cause thermal embrittlement and reduce the mechanical properties of steel. Therefore, the sulfur content should be controlled during the steelmaking process. The binding force between manganese and sulfur is greater than the binding force between iron and sulfur. After adding manganese alloy, it is easy to generate high melting point manganese sulfide together with the manganese in the molten steel and convert it into slag, thereby reducing the sulfur content in the steel and improving the forgeability and rollability of the steel.

(3)As an alloying element

Manganese can strengthen ferrite and refine pearlite, improving the strength, hardenability, hardness, and wear resistance of steel so that it can become an important alloy element of various steels. For example, if 0.8%-1.7% manganese is added to low alloy steel, the strength of the steel can be increased by 20%-30% compared to ordinary carbon steel.

Mn Metal Lump is a new type of Mn metal. Manganese is an indispensable additive in the smelting industry. It is mainly used for desulfurization and deoxidation of steel in the steel industry. It is also used as an additive for alloys to improve the strength, hardness, elastic limit, wear resistance, and c, corrosion resistance of steel. High-alloy steel is also used as an austenite compounding element for refining stainless steel, special alloy steel, stainless steel welding rods, etc. In addition, it is also used in non-ferrous metals, chemicals, medicine, food, analysis and s, and scientific research.

Electrolytic manganese is processed into powder and is the main raw material for the production of trimantri manganese oxide. The original magnetic materials widely used in the electronics industry are produced by trimanganese tetraoxide. The electronics industry, metallurgical industry, and aerospace industry need to electrolyze manganese metal. With the continuous development of science and technology and the continuous improvement of productivity, electrolytic manganese metal has been successfully and widely used in iron and steel smelting, non-ferrous metallurgy, electronic technology, chemical industry, environmental protection due to its high purity and low impurity characteristics. Food hygiene, welding rod industry, aerospace, industry, and other fields.
