【 摘 要 】

In this study, Finite Element Method (FEM) was used to simulate the solidification process of a large blank (280 mm × 325 mm) under different technological conditions. The influence of casting speed and superheat on solidification process of bloom was analyzed. It was found that as the casting speed increases, the solidification position of the bloom moved backward by 3,68 m, and the time required for complete solidification increased by 1 min; When the superheat gradually increased, the position of complete solidification of 10B21 steel bloom moved by about 1,5 m.
