Description
Technical field
The invention belongs to microwave field of smelting more particularly to a kind of methods of microwave Smelting Simn In A.
Background technique
The prior art is when carrying out silicon-manganese alloy smelting, in the chemistry that the high temperature molten bath of manganese alloy smelting is carried out
React more, process is more complicated, Main Analysis several reactions as follows:
SiO2+2C=Si+2CO (1) T begins=1660 DEG C
MnO+C=Mn+CO (2) T begins=1404 DEG C
FeO+C=Fe+CO (3) T begins=712 DEG C
Above three reduction reaction belongs to the endothermic reaction, and wherein the initial reduction reaction temperature of manganese and silicon is higher.Due to
The difference of initial reduction temperature, so the smelting process of silicomangan is substantially that iron and manganese are first reduced out in smelting raw material
Come, generates the MnC of similar high carbon ferromanganese product, the pasc reaction then restored again with high-temperature region.
As Si≤23.5%, following reaction occurs: (Mn, Fe) 7C3+7Si=7 (Mn, Fe) Si+3C (4)
As Si > 23.5%, following reaction occurs: (Mn, Fe) 7C3+10Si=7 (Mn, Fe) Si+3SiC (5)

1300 DEG C) lower than the manganous silicate of manganese and the initial reduction temperature of silicon, the progress of reduction reaction is hindered, thermodynamic condition is limited
System.
Silicone content in silicon-manganese alloy is required 25% or more, and theoretically, the silicone content in product reaches
When 23.5% or more, increase silicon with regard to especially difficult, it is necessary to increase the amount of allocating of reducing agent carbon, mixed carbon comtent height will cause electrode underthrust
