摘要

基于ANSYS有限元软件建立了钒合金电子束熔炼过程的数理模型,对V-4Cr-4Ti合金电子束熔炼过程进行了数值模拟,研究了不同熔炼工艺参数下的熔炼过程温度场分布规律以及熔池形状。结果表明:熔炼过程温度场分布及熔池形状受到熔炼功率及扫描半径的影响。随着熔炼功率的增大,熔池最高温度将会线性增大,熔池宽度和深度将会逐渐增大。随着扫描半径的增大,熔池最高温度将会先增大后减小,通过分析获得了V-4Cr-4Ti合金电子束熔炼的最佳工艺参数。实验结果表明,在优化后的工艺条件下,钒合金电子束熔炼铸锭质量得到一定提升。
        A mathematical model was developed to investigate the electron beam melting(EBM) process of vanadium alloys.The temperature distribution of molten V-4 Cr-4 Ti alloy was obtained using the model. The effects of different parameters of electron beam melting process on the temperature field and the shape of molten pool were studied. The results show that the temperature field and the shape of the molten pool are influenced by the melting power and scanning radius. With increasing the melting power, the maximum melt temperature increases linearly and the width and depth of molten pool gradually increase. With increasing the scanning radius, the maximum melt temperature increases first and then decreases. The optimized parameters of refining vanadium were obtained, and the accuracy of the model was validated by the experimental data.
