烧结矿不同碱度、MgO及SiO2含量水平试验研究

在马钢第三烧结厂原料条件下 ,进行了烧结矿不同碱度、Mg O及 Si O2 含量水平对烧结产质量影响的实验室试验。结果表明 ,随着烧结矿碱度及 Si O2 含量的提高 ,烧结矿强度变好 ;而当 Mg O含量增加时 ,烧结各项技术经济指标均变差。因此 ,生产中烧结矿碱度及 Si O2 含量应分别稳定在 2 .0及 4.95 %水平 ,而 Mg O含量应尽可能降低

Experiment and Study on Effects of Different Basicity and Contents MgO and SiO2 in Sinter

Based on the present material condition of N0.3 sintering plant of Magang, the effects of different basicitys and SiO\-2 and MgO contents in sinter on production and quality of sinter are studied. The results show that, with increasing the sinter basicitys and SiO\-2 contents, the sinter strength is improved, but after increasing the MgO contents in sinter, all sinter technical economic indexes are worsened. Therefore, the sinter basicity should be 2.0, SiO\-2 content should be 4.95%, MgO content should be reduced to the best of its ability in practical production.
