摘　　要：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 MgBased 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.
