Electric furnace refining
Medium and low carbon ferromanganese are generally desiliconized and refined using 1500~6000 kVA electric furnaces, using manganese silicon, manganese-rich ore and lime as raw materials.
The reaction is:
MnSi+2MnO+2CaO─→3Mn+2CaO·SiO2
The use of high basicity slag can reduce the manganese content of the slag and reduce the manganese loss caused by abandoned slag. In joint production, lower slag basicity (CaO/SiO2 is less than 1.3) is used, and the resulting slag with higher manganese content (20~30%) is used for smelting manganese-silicon alloy. Preheating the charge or filling it with liquid manganese-silicon alloy can help shorten the smelting time and reduce power consumption. Refining power consumption is generally around 1000 kilowatt hours. Medium and low carbon ferromanganese are also produced by the hot mixing method, through the mutual heating of liquid manganese-silicon alloy, manganese ore, and lime melt.
