“…For the thermal boundary conditions of the surface and walls of the system, the values commonly used in the literature for this type of vessels were incorporated, which are illustrated in Table . However, to approximate global losses of heat from the steel contained in the industrial ladle an interpreted‐type UDF was programmed, which considers a constant loss of heat in the incoming jet to the tundish of 0.5 K min −1 , as shown in Table .…”

In this work, the multiphase mathematical simulation (steel-slag-air) is performed in order to optimize the fluid dynamics and the homogenization temperature in an asymmetric delta-type billet caster tundish. The performance of the tundish emulates, when a change of ladle occurs, for which are considered the losses of heat through its frontiers as well as the temperature drop of the steel at the input by means of a user defined function (UDF). Also, a comparison is made for the removal of non-metallic inclusions using standard entrapment conditions at the steel-slag interface, as well as a user-defined function (UDF). This UDF takes into account the multiphase interaction with the critical velocity of the particles that approach this interface. For this analysis, it is necessary to determine the opening area of the slag layer. The results of the model for the temperature drop are validated by means of experimental measurements in plant, which show a good correspondence in the obtained data. Finally, the proposed design of flow modifiers favorably influences the fluid dynamics pattern, allowing a better thermal homogenization, and a substantial cleaning of the steel at its output from the tundish.

“…Properly functioning slag systems require controlled steel flow in the tundish to allow inclusions to be released into the slag and chemical reactions to occur effectively at the steel-slag interface [2]. Geometric adjustments to the steel impact point in the tundish are typically achieved using an impact pad, which also helps reduce erosion of the tundish refractory lining [3][4][5]. The high kinetic energy of the incoming steel creates swirl flow at the point of impact, and a suitably shaped impact pad can create a "piston flow" area, which is an essential indicator of flow adjustment quality.…”

To meet the increasing cleanliness requirements in conticast steel production, innovative solutions must be developed. The tundish, which serves as the final refractory-lined reactor, provides ample space to eliminate inclusions through optimization of the steel flow. The key component of the tundish is the impact pad, which determines the flow pattern of steel and is a crucial element of tundish metallurgy. To prevent the formation of dead zones and slag eyes in the slag layer surrounding the ladle shroud, the optimal steel flow within the tundish must facilitate the removal of inclusions through reactions at the steel-slag interface. Additionally, the flow must prevent excessive erosion of the tundish refractory lining. This study compares the standard impact pad with the spherical impact pad using physical modeling, evaluating the residence time and flow within the tundish at three different casting speeds.
