Abstract: More than 94% steelmaking and ironmaking are released in continuous casting process. Product quality is closely related to metal cleanness and non-metallic inclusions removal. So, lliquid metal flow in ladles, tundishes and moulds is recognised to be of great importance in the quality of these products. The metal jet from the ladle to tundish tends to induce turbulent motions which can play important roles in non-metallic inclusions removal at the slag surface, thereby helping in the production of cleaner steel. To improve particle decantation, flow control devices such as dams and weirs are used. The present work is an experimental study released using similarity criteria, through Reynolds and Froude numbers. A reduced scale (1/4) water model of an industrial tundish is used to visualise and measure different parameters of a tracer flow injected in water. The analysis of residence time distribution curves (RTD) by the combined model for different configurations !
is carried out to establish the interest of placing weirs in the amelioration of inclusions flotation and decantation
