利用富锰渣高炉出渣时的液渣潜热,加入白云石粉及石灰粉,可以调节富锰渣的组份,改善其冶金性能。实验室的试验结果表明,在SiO_2含量高达33％的富渣中加入白云石粉和石灰粉,可使软化温度提高到1100℃以上;软化区间可由原来的400℃以上降低到60℃以下。工厂的工业性试验结果表明,在无保温和加温的条件下,用人力搅拌时的石灰粉的最大加入量为5.14％,富锰渣中CaO的含量可由0.5％以下提高到6.14％;白云石粉的最大加入量只有2.6％,富渣中MgO含量仅能由1％左右提高到1.9％左右。实验室和工业性试验的结果,均达到了富锰渣调质的目的。
The use of manganese-rich slag slag blast furnace slag when the latent heat, adding dolomite powder and lime powder, you can adjust the composition of manganese-rich slag to improve its metallurgical properties. The laboratory test results show that the addition of dolomite powder and lime powder to the rich slag with the content of SiO 2 up to 33% can increase the softening temperature to above 1100 ℃; the softening range can be reduced from above 400 ℃ to below 60 ℃. The results of industrial tests showed that the maximum amount of lime powder mixed with human stirring was 5.14% under the conditions of no heat preservation and warming. The content of CaO in manganese-rich slag could be increased from 0.5% to 6.14% The maximum amount of powder added only 2.6%, rich slag MgO content can only be about 1% to about 1.9%. Laboratory and industrial test results, have reached the purpose of quenching and tempering rich manganese residue.
