【摘要】 对于低品位、高二氧化硅原料的烧结,在烧结矿碱度CaO/SiO₂=1.6左右,FeO<14％的条件下,提高烧结矿MgO含量达5.5％以上,可提高烧结矿强度,消除风化,显著改善烧结矿质量和高炉技术经济指标。更多还原

【Abstract】 The sintering technology of low grade and high-SiO₂ raw material was researched. Under the conditions at CaO/SiO₂=1.6±, FeO<14 % in sinter, increasing MgO to more than 5.5% may raise the strength of sinter and eliminate its weathering phenomenon. The quality of sinter and the technical and economical index of BF has been improved significantly.更多还原
