Abstract：There are some inclusions with big size which is originated from slag entrapment in mold at the early stage of stainless steel billet production， and which seriously affects the quality of products. The slag entrapment is related with the steel-slag interface behavior， therefore， the fluid field and interface behavior of steel slag in the mold for stainless steel billet under the condition of different immersion depths of SEN was numerically studied. The results show that when the immersion depth of SEN is below 110 mm， the steel-slag interface can be broken， and the slag can be entrapped into steel. When the immersion depth of SEN is over 130 mm， the velocity of steel at the steel-slag interface is so small that the mass conversion of steel is not enough， which is not beneficial to melt the slag uniformly. Finally， the immersion depth of SEN is adjusted to (120±5) mm in production， and the quality of stainless steel billet is improved greatly.
