Abstract

Abstract: A 1∶1 scale water model tester of twinroll strip casting was set up based on the Froude number and Reynolds number similarity criteria in order to evaluate the new type feeding system. Fluctuation in the surface of the molten pool producing in twinroll strip casting process was studied by hydraulics simulation experiment using DJ800 system. Meanwhile the flow filed distribution inside the molten pool of the twinroll strip casting was studied by solving the continuous equation，NS equation and κε equation using CFD software. Differences of the flow field and surface fluctuation were analyzed on new and old type of the feeding system in Baosteel. The results showed that the new type feeding system had great effect for lowering the wave fluctuation and improving the surface flow filed morphologies of the molten pool. Moreover， the CFD method combined with physical modeling test was suitable for assessing the feeding system used in the strip casting.
