摘　　要：烧结矿低温还原粉化率高,困扰着高炉生产的正常进行。原喷洒CaCl2溶液后,虽低温还原粉化率有降低,但还原度也有所降低,不能满足高炉的需求。试验及工业生产证明喷洒新一代CaCl2活性溶液,可以显著降低烧结矿低温还原粉化率,同时对还原度没有影响,有利于强化高炉冶炼,提高利用系数,降低焦比。When the RDI of sinter is high, it would influence on the production of BF. In the past, spraying CaCl2 solution still cluld not satisfy the blast furnace request. The test and production experience prove that it can reduce the RDI, strengthen BF smelting and improve the productivity by spraying new type CaCl2 active solution.
