WATER MODEL SIMULATION OF TUNDISH FLOW UNDER VARYING CONDITIONS

Water model studies have been conducted to characterise the flow condi tions in continuous casting tundishes under conditions of open and sub merged nozzles. In this investigation simulations of practical problem s of flow interruptions from the ladle, thermal inversions due to unin sulated ladle, and pneumatic agitation near the tundish end wall were conducted. The studies showed that incorporation of suitable flow cont rol devices brings about homogenisation of temperature and composition between strands in the above cases. This study also showed that agita tion of the liquid at the end wall reduces the extent of stagnant zone in the tundish.
