摘要
该工艺是在矿热炉中用焦炭还原锰铁矿石,将还原反应的温度控制为1500℃以下,渣碱度ω_((CaO))/ω_((SiO_2))为0.16,SiO_2的质量分数为18%,生产出的富锰渣中MnO的质量分数不小于70%,同时有副产物碳素锰铁产生。然后将富锰渣热兑人摇炉中,加石灰精炼生产调和渣,使其碱度提高到2.0,这样有利于脱除磷、硫,并降低SiO_2的活度。最后在摇炉中加入工业硅还原调和渣中的锰,获得锰质量分数不小于99%的金属锰,节能效果明显。
In submerged arc furnace,coke was used to reduce manganese iron ore in process,reaction temperature was strictly controlled under 1 500 ℃,slag basicity ω_((CaO))/ω_((SiO_2)) was 0.16,mass fraction of SiO_2 was 18%,mass fraction of MnO in manganese rich slag was not less than 70%.Meanwhile,byproduct carbon ferromanganese was produced.Hot rich-manganese slag was poured into rocking furnace to refine and product harmonic slag which basicity will be increased to 2.0.This condition was beneficial to remove P and S,and decreased activity of SiO_2.Finally,industrial silicon was added to reduce Mn of harmonic slag and get metal manganese,in which mass fraction of Mn was not less than 99%in rocking furnace.It can have a remarkable energy saving effect.
