Reference GB Standard: Ferromanganese (Reference GB Standard: Ferromolybdenum (GB/T 3649-2008))

product description:

Ferromanganese: A ferrous alloy composed of manganese and iron. Main categories: high carbon ferromanganese (7% carbon content), medium carbon ferromanganese (1.0~1.5% carbon content), low carbon ferromanganese (0.5% carbon content), metal manganese, mirror iron, silicon-manganese alloy. Steel work is used as deoxidizer, desulfurizer and alloying agent. In addition to manganese and iron, its composition also includes impurities from silicon, carbon, sulfur and manganese ore.

Application range and purpose:

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

1. Iron and steel industry: Ferromanganese is an indispensable deoxidizer and desulfurizer 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. Desulfurization refers to the removal of harmful substances such as sulfur in steel. , ferromanganese can well achieve the purpose of desulfurization, effectively reduce the content of harmful elements in steel, and improve the quality of steel.

2. Foundry industry: The addition of ferromanganese to cast iron can be used as an inoculant and a nodularizing agent for ductile iron, and can prevent the formation of carbides, promote the precipitation of graphite, greatly shorten the nodularization time, and greatly reduce the form of impurities in molten iron. Cast iron quality, improve cast iron performance. And reduce the blockage of the smelting furnace nozzle, effectively prolong the service life of the 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. Ferromanganese powder can be used as a suspended phase in the mineral processing industry, and used as a coating for welding rods in the welding rod manufacturing industry; high manganese ferromanganese can be used in the electrical industry to prepare semiconductor pure manganese, and in the chemical industry, it can be used to make manganese ketones, etc.
