company news about How to choose ferromanganese in steelmaking process?

The main is cost control, followed by easy operation. High carbon ferromanganese is cheap, low carbon ferromanganese is expensive. High carbon ferromanganese should increase carbon and increase manganese at the same time. Therefore, when adding carbon ferromanganese, be careful not to let carbon out of the grid. However, high carbon ferromanganese is a good choice when the steel needs to be supplemented with manganese and needs to be supplemented with carbon. According to the actual situation, high carbon ferromanganese + medium carbon ferromanganese or high carbon ferromanganese + carbon wire (or carbon particles). Medium carbon ferromanganese contains a small amount of carbon, so the carbon problem is basically ignored except for steel with very low carbon control.
In some steels, steels with very low carbon content, such as some silicon steels (low carbon control) and ultra-low carbon steels, should be considered for the carbon increase factor. At this time, low carbon or micro carbon ferromanganese should be used. The molten steel may not raise carbon.
