The effect of the insert depth (from 100 mm to 200 mm) of the submerged-entry nozzle on the flow field of casting mold based on the continuous caster for stainless steel slabs has been studied by the CFX numerical simulation and water model physical simulation. The result showed that fluid experienced from a single-roll to a double-roll flow pattern with the increase of insert depth. Especially for the 150-mm insert depth, fluctuation height presented a discrete change, and the flow velocity of the liquid lever on both sides of the nozzle was asymmetric due to the formation of flow form with a longer cycle and larger amplitude.
