Manganese and manganese alloys are one of the indispensable important raw materials in iron and steel industry, aluminum alloy industry, magnetic material industry, chemical industry and so on. Manganese is an indispensable additive in the smelting industry, electrolytic manganese processing into powdery is the production of four manganese trioxide main raw materials, the electronic industry widely used in the original magnetic materials is produced with four manganese oxide, the electronics industry, metallurgy and aerospace industry are required electrolytic metal manganese. With the continuous development of science and technology and the continuous improvement of productivity level, electrolytic manganese metal because of its high purity, low impurity characteristics, has been successfully and widely used in iron and steel smelting, nonferrous metallurgy, electronic technology, chemical industry, environmental protection, food hygiene, welding strip industry, aerospace industry and other fields.
In steelmaking production, electrolytic manganese is particularly suitable for smelting alloying elements containing a total of more than 10% stainless steel, heat-resistant steel, precision steel, high-temperature steel, corrosion-resistant steels and other "Special, fine, high " alloy steel and smelting low impurities, low harmful elements of pure steel (∑P, S, O, N, H≤100ppm), pure Steel , N, H≤200ppm) and other steel. According to China's stainless steel, high alloy steel and quality steel and other special steel production and consumption of electrolytic manganese level, 2004 China's stainless steel and other excellent steel smelting consumption of electrolytic manganese about 160,000 tons, of which chromium manganese stainless steel consumption of about 80,000 tons, chromium manganese stainless steel smelting excess, abnormal consumption of 230,000 tons; chromium nickel stainless steel, chrome stainless steel, Heat-resistant stainless steel, precision alloy steel, high-temperature alloy steel, corrosion-resistant alloy steel and other special steel and other steel consumption of about 50,000 tons.
