Intensive steel samples were taken from industrial heats at various time during ladle furnace refining. The compositions, size distribution and morphology of inclusions in the samples were statistically analyzed by using a scanning electron microscope (SEM, ZEISS ULTRA55) and energy dispersive spectroscopy (EDS, OXFORD INSTRUMENTS INCA X-MAX50). The results showed that the inclusions were mainly MgO-CaO-Al2O3 containing little amounts of CaO. The average concentration of MgO in inclusions is about 10% although there is no Mg addition. The inclusion size tended to become larger with Ca concentration increasing in inclusions, and become smaller with Mg concentration increasing.The characteristic of inclusions during hot rolling was also investigated. In addition, the deforming mechanism of inclusions with different modification extents and sizes during hot rolling was proposed.
