Abstract：The internal structure of slab tundish was optimized by water modeling experiment based on the practical production. The results showed that the scheme containing turbulence suppression device， single baffle and double dams was the best solutions. In this condition， the dead zone volume proportion was 0.14%， the active zone volume proportion was 0.23%， which was favorable for the removal of inclusions and increase of yield of molten steel. The submerged nozzle was optimized to use four slag lines during a casting cycle by radium automatic control liquid level function and automatic lifting function of tundish car. Through this operation， submerged nozzle change times was decreased by one， and the purity of molten steel during casting process was improved effectively.
