摘　　要：为了选择合适的钢包吹氩参数,以某厂100t钢包为原型,建立模型与原型尺寸比为1:4的物理模型。通过水模实验对钢包临界卷渣吹氩量进行测量,得到单孔及双孔吹气时的临界卷渣气量是标态450L/min和400L/min,双孔吹气更容易卷渣。讨论了渣层裸露面积的影响规律,单孔和双孔吹气底吹气量分别在大于标态500L/min和400L/min时,渣层表面裸露面积增加不明显。In order to select the appropriate argon blowing parameters,the 100t ladle is taken as the prototype,a physical model of 1/4 linear scale is established.The critical entrapped slag argon flow rate is measured to be 450 L/min and 400 L/min in the condition of single and double bottom argon blowing.The critical entrapped slag is more easily in double bottom argon blowing.The effect rule of slag naked area is discussed.The naked area of slag layer surface is increased little when argon injection rate is more than 500 L/min and 400 L/min in the condition of single and double bottom argon blowing.
