    FRACTURE REASON ANALYSIS OF CHARGING AXLE OF BLAST FURNACE

      Graphical Abstract
      • Abstract
    • A axle of blast furnace charging wagon broke in use. The fracture reason was analyzed by means of macro-morphology inspection,chemical composition analysis and microstructure examination. The results showed that much inclusions existed in the material,which was the source of crack. Moreover,the illogical machining controls accelerated crack growth, that led to the axle broke under normal loading condition.
