The paper presented the influence of liquid debit,teeming spout immer- sed in bath,deep bath,proper dam on the fluid renewal time and flow pat- tern in the tundish by the experiment of water model.Liquid depth and pr- oper dam of tundish are very effective for renewal time and flow pattern iu the tundish. 47〔 〕 化学工程基础 北京大学化学系编 , , 一 一 〔 〕 洪纯一等 , 光歼示 踪仪的研制及在化学工程 中应用 , 北京 化工 学院 , 。 、 “ , 片 二 , , , ‘ 卜 , 一 , 。 , 】 幻口 , , , 。 一 份 卜 万 乓 飞口
