Abstract

본 발명은 내연기관용 엔진(예로, 디젤엔진)의 구성 부품인 실린더 헤드용 고강도, 고내열 CV흑연주철에 관한 것이다.The present invention relates to a high strength, high heat resistant CV graphite cast iron for a cylinder head which is a component of an engine for an internal combustion engine (for example, a diesel engine).

종래의 편상흑연주철재 실린더헤드는 이와 같은 가혹한 조건하에서는 실린더헤드의 열집적부에서 균일이 발생하거나 엔진작동시 실린더헤드에 변형이 일어나 엔진의 성능 저하 뿐 아니라 파손에 의한 교체에 많은 비용이 소요되고 있다.Conventional flaky graphite cast iron cylinder head has a high cost for replacement due to damage as well as deterioration of engine performance due to uniformity in the heat accumulation portion of the cylinder head or deformation of the cylinder head during engine operation under such severe conditions. have.

상기와 같은 문제점을 해결하기 위한 본 발명의 CV흑연주철은 다음의 성분범위를 갖는다. 즉, 중량비로 탄소(C)3.0~3.8%, 규소(Si)2.2~2.8%, 망간(Mn) 0.3 ~ 0.8%, 인(P)0.06%, 황(S)0.03%, 구리(Cu)0.2~0.6%, 크롬(Cr)0.2~0.5%, 니켈 (Ni) 0.5~2.0%, 마그네슘(Mg)0.010~0.035%인 것이 특징이다.CV graphite cast iron of the present invention for solving the above problems has the following component range. That is, carbon (C) 3.0 to 3.8%, silicon (Si) 2.2 to 2.8%, manganese (Mn) 0.3 to 0.8%, phosphorus (P) 0.06%, sulfur (S) 0.03%, copper (Cu) 0.2 ~ 0.6%, chromium (Cr) 0.2 ~ 0.5%, nickel (Ni) 0.5 ~ 2.0%, magnesium (Mg) 0.010 ~ 0.035%.
