Structure optimization of symmetric four-strand tundish
Taking the continuous casting tundish in Huaigang Special Steel Co.Ltd.,the flow characteristics of symmetrical four-strand tundish was studied through establishment of tundish water model.The results showed that there was a big difference in the flow characteristics between two flows on the same side.Compared with the outside flow,the average residence time of inner flow was shorter.The inner flow had a large dead volume.The poor consistency of four streams caused the temperature of molten steel in the tundish uneven,and inclusions could not effectively removed,which could not satisfy the production requirements of special steel.Nevertheless,adding the optimized retaining wall,turbulence promoter et al.could make residence time unanimous,prolong the average residence time and stagnation time,and reduce the dead volume.
