Large iron casting with U-bent steel tube insertion was developed. Water model experiment was performed to clarify the flowing behavior of molten metal in pouring. Effect of the flow on solidification progress was analyzed by the finite element method around the steel tube core print, where the cooling rate is most rapid. The result was examined by a small scale model casting. Experiments and the analysis showed that the molten metal flow were effective to improve bonding of cast iron and inserted steel tubes, and the reason was inferred that the fluid flow of the melt promote the remelting of solidified shell develped at the interface of the steel tubes near the core print.
