Function of flux in smelting high carbon ferromanganese
The main reason for adding flux in high carbon ferromanganese smelting is that it can play the following functions:
1, make harmful impurities to make slag.
2. Control the melting temperature of slag. The melting point of silicon, such as coal Ganges, is 1983 K. If alkaline flux lime and iron ore are added, they will form calcium and iron silicate with silicon dioxide. The melting point of calcium-iron silicate system is generally around 1373 K.
3. Control the side viscosity and density of high carbon ferromanganese slag to separate metal effectively, so as to reduce the loss of metal in slag and improve the recovery of metal.
