Ferromanganese Smelting Process

Ferromanganese smelting process

 

Blast furnace smelting is to smelt ferromanganese by putting raw materials into a blast furnace and heating coal to a certain temperature;

 

Electric furnace smelting is a method that uses electric energy as fuel to quickly bring the raw materials to a certain temperature and fully react to smelt ferromanganese;

 

Electric furnace refining: Medium and low carbon ferromanganese are generally desiliconized and refined using 1500-6000Kv·A electric furnaces. The raw materials are mainly manganese silicon, manganese-rich ore and lime;

 

 Oxygen blowing refining: Use pure oxygen to blow liquid carbon ferromanganese or manganese-silicon alloy columbium to obtain medium and low carbon ferromanganese.

 

Uses of ferromanganese: The uses of ferromanganese can be said to be extensive, but ferromanganese is mainly used in the steelmaking and casting industries. Ferromanganese is usually used as a deoxidizer and desulfurizer during steelmaking. Good steel needs During smelting, deoxidation and desulfurization are carried out, and the use of deoxidizers 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 It can achieve the purpose of desulfurization, effectively reduce the content of harmful elements in steel, and improve the quality of steel.
