摘　　要：介绍了在宝钢不锈钢事业部目前的烧结生产原料和工艺条件下,调整烧结矿的二氧化硅含量,进行烧结杯试验。研究了不同氧化镁含量对烧结矿转鼓强度的影响。结果表明,单纯降低烧结矿中的二氧化硅含量,会造成烧结矿的转鼓强度明显下降;通过不同氧化镁含量与二氧化硅的匹配,烧结矿各项指标可得到优化,满足高炉生产要求。The article introduces the experiment via sintering cup to adjust the silicon dioxide（SiO2）content in sintered ore under the present conditions of raw material and process in Stainless Steel Business Unit of Baoshan Iron and Steel Co.,Ltd.The influence of different magnesium oxide（MgO）content on tumbler strength of sintered ore is studied.The result shows that the mere reduction of silicon dioxide content in sintered ore will lead to decrease the tumbler strength obviously,and each index of sintered ore can be optimized by the adaption using different contents MgO to SiO2.As a result,the demand of blast furnace production can be satisfied.
