| 摘 要： | 在９０００ｋＶＡ电炉中进行了分别用硅石焦和冶金焦做还原剂冶炼硅锰合金的试验，用硅石焦做还原剂，锰回收率由用冶金焦时的７３．５％提高到７６．５％，产品中锰含量由６４．５％提高到６７．２％，电耗平均降低１３５ｋＷｈ。硅石焦是冶炼硅锰合金的优良还原剂。

| Abstract: | Test of silicon-manganese smelting was carryed out in a 9000 kVA furnace using quartzite-coke and metallurgical coke as reductant respectively. The test shows that the recovery of manganeseis increassed to 76.5%from 73.5%, manganese content of metal is increased to 67.2 %from 64.5%and power consumption reduced by 135 kWh/t metal when the quartzite-coke is used instead of metallurgical coke. This proved that quarzite-coke is a fine reductant for silicon-manganese smelting. |
