Abstract��Metallographic examination, SEM and fracture analysis were used to analyse the unqualified medium plate by flaw detection. The results showed that MnS inclusion, crack in center line and bubble were the factors caused the unqualified medium plate. Meanwhile��abnormal structure in the center of medium plate was detected and it increased the brittleness of steel and extended the range of defects during rolling process.
