Applications:
The main functions of manganese ingots in steelmaking are deoxidation, desulfurization and alloying elements.
(1) Used as a deoxidizer
Steel has strict requirements on oxygen content, generally not more than 0.02%, or even more stringent. Therefore, excess oxygen is removed during the steelmaking process. Manganese is a kind of active metal, and its chemical properties are more active 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, and the oxidized slag floats on the surface of molten steel to reduce the oxygen content in the steel.
(2) Used as desulfurizer
Sulfur is present in molten steel in the form of iron sulfide. High sulfur content in steel is prone to hot embrittlement and reduces the mechanical properties of steel. Therefore, the sulfur content should be controlled in the steelmaking process. The binding force of manganese and sulfur is greater than that of iron and sulfur. After adding manganese alloy, high melting point manganese sulfide is easily generated together with manganese in molten steel and converted into slag, thereby reducing the sulfur content in steel and improving the forgeability and rollability of steel.
(3) As an alloying element
Manganese can strengthen ferrite and refine pearlite, improve the strength, hardenability, hardness and wear resistance of steel, so it can become an important alloying 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.
