Abstract

The feasibility of increasing proportion of lump ores in blastfurnace was investigated. The lab results showed that self-softeningand melting properties of the lump ores were dramaticallyimproved by interaction between sinters and lump ores foundin the experiments. Furthermore, the collocation pattern of lumpores and ratio between lump ores was optimized according tointeraction. When the proportion of lump ores was up to 23% or27% at the excellent collocation pattern and appropriate ratio,the burdens still conformed to the requirements of ironmaking.
