Paper Title:
Research on Steelmaking Dust Based on Difference of Mn,Fe and Mo Vapor Pressure
  Abstract

Based on difference of Mn,Fe and Mo vapor pressure,Fe-Mn,Fe-Mo alloys were added into induction furnace and steelmaking dust was collected during smelting process,whose granularity was analyzed by granulometer,microscopic structure and energy spectrum were analyzed by SEM to study characteristics of dust and ulteriorly to explore mechanism of dust generation. It was showed that the mechanism of dust generation was “evaporation theory” and “bubble theory”,dust lied in evaporation had uniform distribution,granularity and element distribution,Mn/Fe ratio of dust was larger than that in molten pool. However, dust caused by spitting or bubbles from molten metal surface had remarkable aggregation,nonuniform granularity and element segregation,Mn/Fe ratio was equal to that in molten pool.
