If the thickness of the solidified layer is not optimal, several problems may arise; if it is too thin, the layer may not be strong enough to support the weight of the molten metal, which can lead to deformation or even collapse. In most research, it is not reported whether the obtained thickness is optimal to ensure the quality of the product, and that is why the primary goals of this project are to examine the effects of Submerged Entry Nozzle (SEN) depth in the funnel-type continuous casting mold of Compact Strip Production (CSP) on flow velocity, temperatureTemperature and steel solidificationSolidification because the quality of the products depends very much on the control of the solidificationSolidification conditions. The SEN depths studied were 260 and 300 mm, these cases were based in operational parameters. The results were validated with those available in literature and theoretical analyses. The jet pouring from the SEN ports is propagated into the mold, and forms two recirculations, one downward and other upward; the lower recirculation decrease as the depths of SEN increased, whereas the upper one increase. As a result, it was found that the thermal fields in both studied cases are similar, but there is a slight difference which shows that a 300 mm SEN depth dissipates and removes heat faster.
