摘　　要：为提高连铸机拉坯拉速,同时确保铸坯质量和安全生产,采用有限元法在ANSYS软件中建立Q345断面250mm×2100 mm的铸坯凝固传热模型进行计算,并经过实际生产验证,拉速由0.8 m/min提升至0.95m/min,采用拉速为1.0 m/min的配水表时,铸坯凝固状态基本满足冶金准则,在二冷七区和八区增加10%的水量,效果良好。In order to improve the casting speed of the continuous casting machine and ensure the quality and safety of the billet,a finite element method was used to establish a solidification heat transfer model for Q345 slab(section 250×2100)in ANSYS software and perform calculations.After practical production verification,when the casting speed was increased from 0.8 m/min to 0.95 m/min and a water distribution meter with a casting speed of 1.0 m/min was used,the solidification state of the casting slab basically met the metallurgical criteria.An increase of 10%water content was added in the seventh and eighth sections of the second cooling zone,and the effect was good.
