摘要
根据承钢高炉冶炼条件，以现场含钛高炉渣为基准，利用熔体物性测定仪研究CaF2、MnO、MgO、Li2O和Cr2O3添加到终渣后对炉渣熔化性能的影响。结果表明这5种添加剂均对炉渣有稀释作用，并且CaF2在0．5％～1．0％，MnO在1．0％，MgO在3％，Li2O在1．0％，Cr2O，在0．5％时分别达到最好的稀释效果。通过对比得到加入合适量添加剂后炉渣TS由低到高的顺序为：氧化锂、氟化钙、氧化镁、氧化铬、氧化锰。
According to current smelting conditions of Chengde Steel and by taking its BF slag as sampies, effects of the addition of CaF2, MnO, Li2O, MgO or Cr2O3 to final slag on melting properties of the slag were studied with melt property tester RTW. The result shows that all of the additives are helpful to reduce the viscidity of slag. With the addition amount of CaF2 of 0.5% - 1.0% , MnO of 1.0%, MgO of 3%, Cr2O3 of 0.5%, or Li2O of 1.0%, the best dilution effect is achieved. With an addition amount of 0.5%, the additives listed in order of decreasing effect are Li2O, CaF2, MgO, Cr2O3 and MnO.
