The effect of varying ladle stream temperature on the fluid flow and heat transfer phenomena in a typical twin strand slab caster tundish has been mathematically modeled in the present study. The model involves the solution of the transient, three dimensional form of the turbulent Navier-Stokes equation, alongside the equations of turbulence energy, energy dissipation rate of turbulence energy, and thermal energy conservation. The temperature of the incoming melt stream is assumed to decline at a constant rate of 0.5°C/min over a casting period of 50 min. Under the examined conditions, the temperature of the incoming melt stream is projected to become lower than the bulk temperature of the melt in the tundish by about 1-2°C after 25 min from the start of teeming. Due to buoyancy effects, the cooler incoming melt begins to flow along the bottom of the tundish rather than the normal top free surface directed flow. The calculations reveal that this inverse flow pattern develops over the remaining teeming period and persists for about 1 min into the next heat's teeming. Consequently, the flotation and removal of non-metallic inclusions during the latter half of the casting period are expected to be less effective compared to the first half.
