The hydraulic turbine runner equipped in Three Gorges Power Station has the biggest size and strictest mechanical properties requirement in the world.The turbine runner consists of crown, band,and blade, which are cast and heat treated separately and then welded together.In order to eliminate the casting flaws, especially the casting deformation in blade that with complex profile, an integral finite element method model based on ProCast software was developed to simulate the deformation of the blade during the whole hot procedure including casting, shake-out, cutting-off the gating system and heat treatment.
