• 中文摘要： 本研究探討大鋼胚連續鑄造程序中之凝固熱傳的數學解析與電腦模擬。本研究提出了一個有效的模擬計算程式, 並且研究各種操作情況, 如澆鑄速度, 冷卻水密度等之改變對於鑄造結果之影響。本研究應用二維有限差分法來計算具有移動相邊界之熱傳問題。模擬計算所得之大鋼胚表面溫度與實驗測量值十分吻合。本研究並提出表面溫度分佈, 凝殼厚度以及各種操作條件改變時對連續鑄造結果之影響之各項數據。
• 英文摘要： This study presents the mathematical analysis and computer simulation results of heat transfer during solidification in the continuous casting process. Through this work, an effective model for simulating such process is established. The effects of the operating conditions, for example, the casting speed and the cooling water density, on the performance of the casting process are also studied. Finite difference numerical method is used to solve the two- dimensional heat transfer equation with moving boundary. Surface temperatures of blooms are calculated and good agreement with experimentally measured data is obtained. Simulation results of the surface temperature profile, the thickness of the solid shell and the effects of the different operating conditions are presented.
