Abstract In this work, the feasibility of increasing proportion of lump ores in blast furnace was investigated. The lab results showed that self-softening and melting properties of the lump ores were dramatically improved by interaction between sinters and lump ores found in the experiments. Furthermore, the collocation pattern of lump ores and ratio between lump ores was optimized according to interaction. When the proportion of lump ores was up to 23% or 27% at the excellent collocation pattern and appropriate ratio, the burdens still conformed to the requirements of ironmaking.
