2.Uses of ferromanganese:

Ferromanganese is widely used in the steel industry, foundry industry, and other industrial production.

A. Steel industry: Ferromanganese is an indispensable deoxidizer and desulfurized in the steelmaking industry. Good steel needs to be deoxidized and desulfurized during smelting, and the use of deoxidizer will greatly increase its cost. Therefore, ferromanganese is a cheap deoxidizer, and desulfurization refers to the removal of sulfur and other harmful substances in steel. , Ferromanganese can well achieve the purpose of desulfurization, effectively reduce the content of harmful elements in the steel, and improve the quality of the steel.

In the steelmaking industry, each ton of steel produced consumes approximately 3 to 5 kg of 75% ferromanganese.

B. Foundry industry: Ferromanganese can be used as an inoculant and spheroidizing agent for nodular cast iron when added to cast iron, and can prevent the formation of carbides, promote the precipitation of graphite, greatly shorten the spheroidization time, and can also greatly reduce the form of impurities in the molten iron. The quality of cast iron improves the performance of cast iron. And reduce the blockage of the smelting furnace's nozzle, and effectively extend the service life of the smelting furnace.

C. Other industries: high-carbon ferromanganese or manganese alloys are used as reducing agents in the production of low-carbon ferroalloys in the ferroalloy industry. Ferromanganese powder can be used as a suspended phase in the beneficiation industry and used as a coating for welding rods in the welding rod manufacturing industry; high-manganese ferromanganese can be used to prepare semiconductor pure manganese in the electrical industry and can be used to manufacture manganese ketones in the chemical industry.
