摘要
以通道模型和Maecker线性化方法为基础,结合等离子弧表面淬火的工艺过程,从理论上对等离子弧表面淬火热源参数进行分析计算,获得了等离子弧表面淬火热源热流密度分布的表达式,并通过ANSYS软件,将计算结果应用于45#钢等离子弧表面淬火过程的温度场模拟中,得到了45#钢工件的淬硬层深度和宽度,通过与45#钢的淬火实验结果对比,两者在误差范围内非常吻合,从而验证了该计算方法的正确性。
In this paper, the heat source parameter of plasma arc surface quenching is analyzed and calculated in theory based on the channel model and Maecker linearization method combing with the process of plasma arc surface quenching, and the ex-pression of heat flux density distribution of plasma arc surface quenching is obtained . The temperature field of the plasma arc surface quenching process of 45 steel is simulated with the results of the calculation and ANSYS software, and the quenching depth and width of the workpiece is obtained. By comparing the simulated results with the experimental results of 45steel, they are in good agreement with the error range and thus the correctness of the calculation method is verified.
