摘　　要：通过运用FLUENT软件,对日照钢铁BB2断面异型坯进行结晶器流场及温度场的数值模拟及分析。对比不同拉速、过热度和浸入式水口插入深度条件下的流场变化,模拟出不同条件下的坯壳表面温度和坯壳厚度,为后续的质量改进提供了有力的理论依据。Through the application of FLUENT software,the numerical simulation analysis of the flow field and temperature field of BB2 cross-section of Rizhao steel was conducted.The surface temperature and shell thickness of the blank shell under different conditions were simulated by comparing the variation of the flow field under different drawing speed,superheat and submerged nozzle,it provides a powerful theorectical basis for the subsequent quality improvement.
