The study aimed to develop an ultra-pressure water-jet pump main body using ductile cast iron FCD500, conducted quantitative analysis on the phenomenon of flow or solidification processing for improvement of cast devise. After the selection of ideal condition of cast, it applied to cast of real product shape which is discovered the ideal filling processing under this condition that temperature of molten metal was between 1280℃ and 1300℃. Apart from finishing filling, solidification was commenced rapidly when percentage of solidification completion was between 40-50%, at that moment; the temperature was measured at 1100℃. Moreover, under the condition of temperature below than 900℃, keeping temperature on the center of parts for a certain period of time brings stability of stabilization of heat in parts and organizational stabilization of ductile cast iron.
