摘　　要：为减少胎圈钢丝拉拔生产中热处理参数选择的试验工作量,确保产品质量并降低生产成本,以钢丝在加热炉中传热理论为基础,建立传热数学模型,设定边界条件,采用有限元分析方法模拟计算不同直径钢丝在加热过程中表面温度、截面温度分布等参数,从而确定其满足奥氏体化工艺温度要求的热处理线速度。结果表明,对于直径为3.5 mm和4.7 mm的胎圈钢丝,能满足奥氏体化工艺温度要求,使热处理终点温度达到940℃左右的最佳热处理线速分别为18 m/min和13.5 m/min,且与实际生产相吻合。有限元模拟分析试验可实现钢丝加热问题的可视化研究。To reduce the test work of heat treatment parameter selection in bead wire drawing production,ensure product quality and reduce production cost,based on heat transfer theory of steel wire in heating furnace,to established heat transfer mathematical model,set boundary conditions.Using finite element analysis method to simulate and calculate surface temperature,section temperature distribution and other parameters of different diameter steel wire in heating process,so as to determine the heat treatment line speed that can meet the austenitizing process temperature requirements.The results show that the bead wire with diameter 3.5 mm and 4.7 mm can meet the requirements of austenitizing process temperature,and the optimal heat treatment speed is 18 m/min and 13.5 m/min when the end temperature of heat treatment reaches about 940℃,which is consistent with the actual production.Such results suggest that using finite element simulation can realize the visualized investigation of steel wire.
