摘要: 在專門設計的二維模型上對非等溫流現象的形成條件進行了實驗研究,定義了衡量非等溫流動出現的準數,并給出了臨界值,以用來判斷中間包內溫度差對鋼水流動的影響程度．對中間包非等溫流動的形成過程進行了數值模擬,并在40t中間包上做了生產現場的直接測量．結果表明,在正常生產條件下,中間包內流體流動是一個典型的非等溫過程．

Abstract: The formation of non-isothermal flow in a tundish was investigated in a special designed 2D water modelling system. The critical condition of the formation of non-isothermal flow was proposed to be a number Zb evaluating the sensitivity of tundish flow to temperature difference. CFD simulation of the tracing pattern in a water model described in the initial formation condition of non-isothermal flow. A direct measurement of temperature stratification in a 40 t tundish confirmed the existence of the non-isothermal flow.
