摘要: 通過對連續定向凝固過程的傳熱理論分析,建立了臨界牽引速度與其相關因素之間的關系式。當噴水位置到固液界面距離L ≤ 10mm時,純Al和Al-1%Cu合金計算結果與實驗數據基本吻合。由此而確定的各種參數之間能夠達到很好的相互匹配,可確保連續定向凝固的穩定進行。還通過分析各種因素對臨界牽引速度的影響,提出了提高臨界牽引速度的途徑。

Abstract: The relation between critical pulling velocity and its effect factor is made by heat transport theoretical analyzing of continuous unidirectional solidification. When the distance of spraying position of forced cooling ingot and the liquid-solid interface is shorter than 10 mm.(L ≤ 10 mm),the calculated result of Al and Al-1% Cu alloy continuous unidirectional solidification is approximately identical with experimental result. All of calcu-lated and experimental parameters are quiet matching, and the continuous unidirectional solidification can be stably performed. The way of raising pulling veloc-ity is also mentioned.
