What is ferromanganese? What is ferromanganese used for?
Ferro Manganese is commonly spelled as an alloy of Manganese and iron. Its raw materials are generally manganese ore, coke and lime which are melted in high temperature environment and fully reacted to smelting and become ferromanganese. Because coke is added in the smelting process, there is a certain amount of carbon elements inside. According to the content of carbon elements, ferromanganese can be divided into low carbon ferromanganese, medium carbon ferromanganese and high carbon ferromanganese.
And ferromanganese USES could be called widely, but in ferromanganese is mainly used in steelmaking and casting industry, steelmaking ferromanganese is usually used for deoxidizing agent and desulfurizer used, good steel needs in smelting is deoxidized desulfurization process, and using deoxidizing agent will greatly increase the cost, therefore, ferromanganese is a cheap deoxidizer, desulfurization is refers to the sulfur in the steel from harmful substances, such as ferromanganese we can achieve the purpose of the desulfurization very well, effectively reduce the content of harmful elements in steel, improve the quality of steel.
In casting is good promoter and ferromanganese nodularizer, when casting in ferromanganese can effectively make the graphite spheroidizing, greatly shorten the time of spheroidizing, on the other hand ferromanganese can also sharply reduce molten iron impurities in the form, improving the quality of cast iron, nozzle blocking and reducing smelting furnace, effectively extending the service life of the smelting furnace.
