摘要

本研究的目的主要為考慮未來精煉如矽、鈦合金時，為使製程參數有一最佳的控制，以得到最佳的精煉效果，因此有必要事前對電漿電磁場溫度場等有所認識及研究。研究工作在目前階段希望藉由電腦軟體FEMLAB，探討電漿爐中的能量、動量和質量的傳輸過程，及電漿體內的電磁場、流場、熱傳場的相對變化與交互影響，將所獲得的計算結果與文獻比對，如可獲得相似曲線，則可證明本研究模型已具有準確之定性與半定量解。

In order to optimize the process parameters and to have the best refining efficiency in plasma refining of alloys such as titanium、silicon etc. Hence, this paper will present the work of simulation of plasma refining, especially the temperature distribution of plasma arc. At present, the analysis combined the energy momentum、mass transport phenomena and the relationship between the electromagnetic flow and heat transfer field in the plasma. The model of plasma refining was analyzed by finite element method with commercial software (FEMLAB). The results of the simulation are compared with the literature data and the model can be proved to be qualitatively. Precise when the comparison gives similar curves.
