High-carbon ferromanganese smelting add flux is mainly due to its addition can play the following roles:
1, make harmful impurities slagging.
2, control the melting temperature of the slag. Ore gangue and other silicon, silicon melting point 1983 k, if you add alkaline flux lime and iron ore, they are generated with silica calcium iron silicate, calcium iron silicate system melting point is generally 1373 k or so, due to the addition of the basic flux and slagging temperature from 1983 k to 1373 k or so, so it can be melted at low temperatures.
3,Control the viscosity and density of high carbon ferromanganese slag side effectively separated from the metal, thus reducing the loss of metal in the slag and improving the recovery rate of metal.
