改善石钢烧结矿质量的试验研究

Study on Improving Intensity of Shigang′s Sinter

研究了不同MgO含量、碱度及Al2O3/SiO2对烧结矿常温强度及冶金性能的影响。结果表明,MgO对烧结矿常温强度有双重的影响,其含量在2.3%时强度有最佳值,烧结矿质量随碱度值的增加而得到改善。随着Al2O3/SiO2的增加烧结矿强度变差,粉化严重。

The paper studied on the effect of different contents of magnesium oxide, basieity and Al2O3/SiO2 to the strength and metallurgy performance of sinter. The result indicated that MgO had two sides, and when it got 2.3%, all the standards were the most appropriate. The strength of sinter was improved with the basieity increased. At last, the strength and metallurgy performance of sinter got worse.
