Abstract
Investigating the impact of circumferential water flow density distribution on heat transfer and solidification behavior is an important foundation for accurately simulating the solidification heat transfer process and effectively controlling the quality of ultra-large-section beam blanks during continuous casting.This study focuses on the Q235 steel ultra-large-section beam blank,establishing a simulation model for secondary cooling heat transfer and solidification in continuous casting.By comparing the heat transfer and solidification behavior under average water flow density distribution and circumferential water flow density distribution,the influence of circumferential water flow density distribution on the heat transfer process was explored.The results demonstrate that circumferential water flow density distribution significantly affects the temperature at the flange tip outer corner and the web surface center.Considering circumferential water flow density differences,the maximum temperature at the flange tip outer corner and the web surface center increased by 342℃and 166℃,respectively.Therefore,accurate simulation of the continuous casting heat transfer and solidification process must incorporate circumferential water flow density distribution.关键词
