摘　　要：增加烧结矿中w(MgO),从而提高高炉渣中w(MgO)是改善高炉炉渣性能的1种主要措施。设计了3组试验方案:方案1为渣中w(Al2O3)为18%,w(MgO)/w(Al2O3)为0.72,R4为0.95,R2为1.08;方案2为渣中w(Al2O3)为实际值,w(MgO)/w(Al2O3)为0.72,R2为1.1;方案3为渣中R2为1.1,烧结矿中w(MgO)为1.80%,并采用在高炉中加入白云石的方法满足渣中MgO的要求。结果表明,方案2烧结生产率提高,转鼓强度最高,达64.27%。It is one of main measures to improve the performances of blast furnace slag by increasing w（MgO） of sinter and w（MgO） of slag. Three schemes were designed as follows： In No. 1 scheme, w（Al2O3） of slag was 18%, w（MgO）/w（Al2O3） was 0.72, R4 was 0.95, R2 was 1.08; In No. 2 scheme, w（Al2O3） of slag was the actual data, w（MgO）/w（Al2O3） was 0.72, R2 was 1.1;In No. 3 scheme, R2 of slag was 1.1; w（MgO） of sinter was 1.80 %, and it can meet the requirement of w（MgO） of slag by adding dolomite in BF. The test results show that in No. 2 scheme sintering productivity increased and TI was the highest, i. e 64. 27%.
