The purity of electrolytic manganese is very high, its role is to increase the hardness of the metal material, the most widely used manganese copper alloy, manganese aluminum alloy, 200 series stainless steel, manganese in these alloys can improve the alloy strength, toughness, wear resistance and corrosion resistance.
Manganese and manganese alloy is one of the indispensable important raw materials in iron and steel industry, aluminum alloy industry, magnetic material industry and chemical industry.Manganese is an indispensable additive in smelting industry, and electrolytic manganese processing into powder is the main raw material for the production of manganese trioxide. The magnetic materials widely used in the electronic industry are produced with manganese trioxide, and the electronic industry, metallurgical industry and aerospace industry all need electrolytic manganese metal. With the continuous development of science and technology and the continuous improvement of productivity level, electrolytic metal manganese due to its high purity, low impurity characteristics, has been successfully and widely used in iron and steel smelting, non-ferrous metallurgy, electronic technology, chemical industry, environmental protection, food hygiene, welding rod industry, aerospace industry and other fields.
China's electrolytic manganese production is mainly 99.7% of the products (now most manufacturers have actually reached 99.8%), only a few manufacturers produce 99.9% of the products, the main raw material-manganese ore for manganese oxide and manganese carbonate ore, in addition to the previous process of liquid production method is not the same, electrolytic production process is basically the same.
In steelmaking production, electrolytic manganese is especially suitable for smelting alloying elements containing more than 10% total stainless steel, heat resistant steel, precision steel, precision steel, high temperature steel, corrosion resistant steel and other "special, fine, high" alloy steel and smelting low impurity, low harmful elements of pure steel (P, S, O, N, H 100ppm), pure steel (P, S, O, N, H 200ppm) and other steel.
According to the macro development trend of China's national economy and iron and steel industry,Stainless steel and other excellent special steel industry is on the rise, domestic stainless steel industry, production capacity, output and market demand is developing at a high speed, stainless steel and other high-end products excellent special steel smelting electrolytic manganese demand, the overall still remains strong.
To well grasp the development of the electrolytic manganese industry, the situation of the downstream manufacturers is naturally closely related. In addition to 200 stainless steel, electrolytic manganese is also used in the production of special steel and excellent steel, in which special steel can also be used as manganese ingot or cheaper high carbon ferromanganese.
