Abstract
In order to study the influence of flow control devices on the molten steel flow field in a 78 ton large double strand symmetrical tundish in a certain steel plant,a combined method of numerical simulation and water modeling was adopted to investigate the effects of changes in different flow con-trol devices.The 1∶1 modeling of the prototype tundish under the Euler-Euler framework was estab-lished to study the influence of the presence or absence of dam holes,the distance between dam and ladle shroud,the distance between weir and ladle shroud,the height of turbulence inhibitor,the distance between weir and bottom of tundish and the height of dam on the molten steel flow field in the double strand tundish.The results show that with increasing the height of turbulence inhibitor,and decreasing the distance between weir and the bottom of tundish,the average residence times of molten steel in tun-dish increase obviously,and the volume fractions of dead zone decrease significantly.In addition,the dam without holes can effectively inhibit the development of short-circuit flow,extend the flow dis-tance of the molten steel and increase the average residence time.When the distance between the dam and the ladle shroud is increased,the average residence time first increases and then decreases.With in-creasing the distance between weir and ladle shroud,the short-circuit flow to steel outlet through dam holes is developed,and the average residence time decreases.关键词
