DESCRIPTION
The main classification of ferromanganese: high carbon ferromanganese (containing 7% carbon), medium carbon ferromanganese (containing 1.0~1.5% carbon), low carbon ferromanganese (containing 0.5% carbon), metal manganese, ferric mirror, silicon manganese alloy.In steelmaking, used as deoxidizer and alloy additives, is the largest amount of ferroalloy.
