Hydraulic simulation of the feeding system in the strip casting process

摘要

A 1∶1 water model of a twin-roll strip caster was set up based on the Froude number(Fr) and Reynolds number(Re) similarity criteria.Fluctuation and the mixing effect in the molten pool of twin-roll strip casting process were analyzed through hydraulic simulation.The height of the fluctuation of the liquid pool surface and the residence time were measured by DJ800 multifunctional monitor under different process conditions.The results show that the casting velocity,the insertion depth and the pool level have a great effect on the fluctuation.
