    摘要:

    研究了底漏式真空吸鑄成形方法制備鈦合金小型葉輪鑄件的可能性。首先研究了底漏式真空吸鑄工藝參數(shù)對TA15合金在水平方向的螺旋形型腔內(nèi)流動(dòng)性的影響,然后研究了工藝參數(shù)對1mm厚薄板鑄件在重力方向上充填率的影響,最后采用合理工藝參數(shù)成功吸鑄出鈦合金葉輪,葉輪鑄件輪廓完整,棱角清晰。結(jié)果表明,氣體壓力對充型能力有決定性影響,合金液不僅在重力方向具有很強(qiáng)的充型能力,而且在水平方向也能夠很好地充填型腔。

    Abstract:

    The possibility of minitype titanium alloy impeller cast preparation by bottom vacuum suction casting was studied. At first, the effects of the processing parameters of bottom pouring vacuum suction casting on the horizontal flowability of TA15 alloy in a spiral mold cavity were investigated; then their effects on the filling ratio in gravity direction of a 1 mm thick plate was researched; finally a TA15 impeller was produced by employing reasonable processing parameters. The impeller cast has an integrated structure and fine edges and corners. Results show that gas pressure has a predominant effect on the filling process. The melt has a good filling ability both in vertical and horizontal direction.
