    摘要:

    模擬研究了TiAl合金感應(yīng)凝殼熔煉過程的熱場和流場分布，探討了安培匝、電源頻率以及坩堝與感應(yīng)線圈的相對位置等電磁參數(shù)對熱及流場分布的影響規(guī)律，模擬模型通過實(shí)驗(yàn)測得的磁感強(qiáng)度以及攪拌駝峰高度進(jìn)行了有效驗(yàn)證，并對模擬結(jié)果進(jìn)行了詳細(xì)的分析討論

    Abstract:

    The electromagnetic, thermal and fluid fields during ISM (Induction Skull Melting)of TiAl alloy are simulated. The effects of ampere-turn, frequency and relative position between crucible and coil on the distribution of thermal and flow fields are numerically studied. The simulation model is verified by experiments and the simulation results are discussed in detail
