Introduction
Ferro manganese is an alloy composed of manganese and iron and is produced by blast furnaces or electric furnaces. High carbon ferro manganese produced by electric furnace is mainly used as deoxidizer, desulfurizer and alloy additive for steelmaking. In addition, with the progress of low carbon ferro manganese production technology, high carbon ferromanganese can also be used to produce low carbon ferro manganese.
Ferro manganese is very important in steelmaking and casting. It can improve the hardness, strength and wear resistance of steel, and improving the cutting characteristics of castings.
Application
- Ferro manganese is an indispensable cheap deoxidizer and desulfurizer in the steelmaking industry.
- MnS generated after desulfurization of ferro manganese can improve the cutting performance of castings.
- High carbon ferro manganese is used as a raw material for the production of low carbon ferroalloys.
- Improve the mechanical properties of castings, and increase the hardness and strength of castings after hot rolling.
- Used as an inoculant and nodulizer for cast iron, prevent the formation of carbides, improve the properties of cast iron.
