Mn metal lump 95/97 knowledge
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.
The ferro silicon manganese produced by ZhenAn is considered to be of high quality in the Chinese and international markets.
