| Abstract: | Softening dropping properties of sinter and pellet which Jinan steel＇ s blast furnaces are using now and proposed sinter were analyzed by RDL-02 device. The results showed that the softening dropping properties of 60 sinter and 120 sinter were similar; the start-of-softening temperature and start-of-melting temperature of 320 sinter were higher than that of 60 sinter and 120 sinter, its maximal differential pressure was 11 608 Pa, lower than the other two kinds of sinter; The softening-melting properties of 320 sinter were better than that of 60 sinter and 120 sinter. These results will provide scientifie evidence for blast furnace burden. |
