非对称中间包结构优化与应用OA

A combination of physical modeling and numerical simulation has been employed to investigate the effects of different flow-control schemes on the molten steel flow field and temperature field within the tundish.The results indicate that under water-model conditions,the response time and peak time of the two streams in the original scheme differ significantly,the consistency between the two streams is poor,and the average dead-zone volume fraction is as high as 33.45％.After increasing the dam height and enlarging the distance between the dam wall and the dam,the consistency of the two streams is markedly improved,and the average dead-zone volume fraction decreases to 14.55％.Practical application results show that the temperature difference of the molten steel above the two nozzles in the tundish decreases from 4～6℃to 2～3 ℃,and the total oxygen content in the cast billet is reduced by approximately 27.9％.These findings illustrate that the optimized scheme effectively enhances the metallurgical performance of the tundish and improves the quality of the cast billet.
