Description

Application
erro Manganese: There are two kinds of reduction smelting of ferromanganese: flux method (also known as low manganese slag method) and flux-free method (high manganese slag method). The principle of the flux method is the same as that of blast furnace smelting, except that electric energy is used instead of coke for heating. By adding lime to form high basicity slag (CaO/SiO2 is 1.3~1.6) to reduce the loss of manganese. The flux-free smelting method does not add lime, resulting in a low-iron, low-phosphorus, and manganese-rich slag with low alkalinity (CaO/SiO2 less than 1.0) and high manganese content. The amount of slag in this method is small, which can reduce power consumption, and the evaporation loss of manganese can be reduced due to the low slag temperature. At the same time, the by-product manganese-rich slag (containing 25~40% manganese) can be used as the raw material for smelting manganese-silicon alloy, which can achieve higher Comprehensive recovery rate of manganese (above 90%). Most modern industrial production uses flux-free smelting of carbon ferromanganese, and forms a joint production process with the smelting of manganese-silicon alloys and medium and low carbon ferromanganese.
