In this study, the main objective is to develop a mathematical model to simulate the flow behavior of molten steel in billet continuous casting mold. The results can aid the actual operation in continuous casting process. In order to understand the flow behavior of molten steel in casting mold, a mathematical model based on SOLA(1)) method has been developed to analyze the three dimensional turbulent flow conditions. The flow pattern in the casting mold can be described by the analysis and the effects of submerged nozzle design and operating conditions on the flow behavior can be evaluated. The efficiency rate of nonmetallic inclusion removal can be also estimated.
