What is the use of ferromanganese? Let's introduce:
1. Steel industry: ferromanganese is the deoxidizer and desulfurizer in the steel-making industry. Good steel needs to be deoxidized and desulfurized during smelting, and the use of deoxidizer will increase its cost. Therefore, ferromanganese is a cheap deoxidizer. Desulfurization refers to the separation of sulfur and other harmful substances in steel. Ferromanganese can achieve the purpose of desulfurization, effectively reduce the content of harmful elements in steel and improve the quality of steel. In the steelmaking industry, about 3 ~ 5kg 75% ferromanganese is consumed for each ton of steel.
2. Casting industry: Ferromanganese added to cast iron can be used as inoculant and spheroidizing agent of nodular cast iron, prevent the formation of carbide, promote the precipitation of graphite, shorten the spheroidizing time, greatly reduce the form of impurities in molten iron, improve the quality of cast iron and improve the properties of cast iron. And reduce the blockage of smelting furnace nozzle, and effectively prolong the service life of smelting furnace.
3. Other industries: high carbon ferromanganese or manganese alloys are used as reducing agents for the production of low-carbon ferroalloys in the ferroalloy industry. It can be used as suspended electrode powder in ore dressing industry; High manganese ferromanganese can be used to prepare semiconductor pure manganese in electrical industry and manganese ketone in chemical industry.
