sắt mangan

Ferromanganese is an alloy of manganese and iron, which also contains a small amount of other elements such as carbon, silicon and phosphorus. According to the different carbon content, it can be divided into high carbon ferromanganese, medium carbon and low carbon ferromanganese. Ferromanganese alloys containing enough silicone are called manganese-silicon alloys. The higher the silicon content of the alloy. The lower its carbon and phosphorus content.

As a deoxidizer and desulfurizer.The affinity between manganese and oxygen is greater than that between ironand oxygen and almost all steel types must be deoxidized with ferromanganese. In the steel making process, manganese can also reduce FeSi to generate stable MnSi that is insoluble in molten steel,so manganese is also a desulfurizer.
