Title (EN) SPHEROIDAL GRAPHITE CAST IRON, MANUFACTURING METHOD THEREFOR, AND HYDRAULIC DEVICE COMPONENT MANUFACTURED THEREFROM
(FR) FONTE À GRAPHITE SPHÉROÏDAL, SON PROCÉDÉ DE FABRICATION ET COMPOSANT DE DISPOSITIF HYDRAULIQUE FABRIQUÉ À PARTIR DE CETTE DERNIÈRE
(KO) 구상 흑연 주철 및 이의 제조방법, 이로부터 제조된 유압기기용 부품
Abstract: front page image
(EN)The present invention relates to spheroidal graphite cast iron, a manufacturing method therefor, and a hydraulic device component manufactured therefrom. The present invention can provide the spheroidal graphite cast iron having uniform spheroidal graphite and matrixes by specifically controlling the ratio (Cu/Zr) of the copper (Cu) content to the zirconium (Zr) content.
(FR)La présente invention se rapporte à une fonte à graphite sphéroïdal, à son procédé de fabrication et à un composant de dispositif hydraulique fabriqué à partir de cette dernière. La présente invention peut fournir la fonte à graphite sphéroïdal présentant un graphite sphéroïdal uniforme et des matrices uniformes par régulation précise du rapport (Cu/Zr) entre la teneur en cuivre (Cu) et la teneur en zirconium (Zr).
(KO)본 발명은 구상 흑연 주철 및 이의 제조방법, 이로부터 제조된 유압기기용 부품에 관한 것으로, 본 발명은 지르코늄(Zr)의 함량 대비 구리(Cu)의 함량의 비(Cu/Zr)를 특정하게 조절함으로써 구상 흑연 및 기지조직이 균일한 구상 흑연 주철을 제공할 수 있다.
