The technology of spraying sinter with CaCl2 can improve the RDI while impacts the metallurgy performance of other raw materials in blast furnace.In order to understand the influence of CaCl2 on RDI and weight loss rate of iron ore during their low temperature reduction process,the sinter and pellet had been investigated.The results showed that RDI+3.15 of sinter after CaCl2 solution treated increased and the weight loss rate decreased at low temperature(<900℃).Especially in the temperature range of 500~700℃,CaCl2 exearted considerable inhibition effect on the reduction of sinter and obviously affected the reduction process of pellet.For the pellet the effect was weaken gradually when temperature exceeding 700℃.
