Abstract：The susceptible corner crack, center segregation and inclusions and other defects in continuous casting heavy plate affected the quality of the heavy plate greatly. Technologies for heavy plate to prevent corner crack, homogenization control and internal inclusions control were studied by theoretical analysis, simulation calculation, lab experiments and field experiments. The results showed that the heavy plate products were in high quality without corner crack, and the central segregation level concentrated in the range of C0.5-C1.5. The average inspection qualified rate of the heavy plate was 96%. The results of this study was significant to the quality control of the production of heavy plate.
