A kind of method of microwave Smelting Simn In ATechnical field
The invention belongs to microwave field of smelting, more particularly to a kind of method of microwave Smelting Simn In A.
Background technology
Prior art is when carrying out silicon-manganese alloy smelting, the chemistry carried out in the high temperature molten bath of manganese alloy smelting
Reaction is more, and process is more complicated, the following several reactions of Main Analysis：
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 the initial reduction reaction temperature of wherein manganese and silicon is higher.Due toThe difference of initial reduction temperature, is first reduced out so the smelting process of silicomangan is substantially iron and manganese in smelting raw materialCome, generate the MnC of similar high carbon ferromanganese product, the pasc reaction then restored again with high-temperature region.
As Si≤23.5%, occurs following reaction：(Mn, Fe) 7C3+7Si=7 (Mn, Fe) Si+3C (4)
As Si ＞ 23.5%, occurs following reaction：(Mn, Fe) 7C3+10Si=7 (Mn, Fe) Si+3SiC (5)
