Abstract In order to improve the flow field of the beam blank continuous casting mold in a steel plant, the physical simulation research was carried out based on this mold, and the nozzle structure was optimized. The flow field display, wave height measurement and conductivity measurement were used to study the influence of different nozzle structure on the mold flow field and the change rule of mold flow field under different nozzle structure. The results show that the liquid level fluctuation of the mold is better under the experimental conditions with the bottom hole diameter of 17 mm and the air blowing capacity of 3 L/min, and there are better particle and ink flow fields in the mold. In the actual production, it is beneficial to the uniformity of temperature and composition in the mold, which is conducive to the formation of good solidified shell, and it is not easy to produce slag in the casting process.
