Abstract
본 발명은 고인성 구상 흑연주철과 그 제조방법에 관한 것으로서, 특히 주철에 Mg, Fe등을 첨가하여 흑연을 구의 형태로 고립되게 석출시킨 구상흑연주철에 있어서, 상기 구상흑연주철의 기지조직중 페라이트 분율이 20%이상 존재하고, 퍼얼라이트의 평균입경이 300㎛이하인 것을 특징으로 하는 고인성 구상흑연주철에 관한 것이다.The present invention relates to a high-strength spheroidal graphite cast iron and a method for producing the same, and more particularly, to a spheroid graphite cast iron in which Mg and Fe are added to cast iron so that graphite is isolated in spherical form, And the average particle size of the pearlite is 300 탆 or less.
Description
본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음Since this is a trivial issue, I did not include the contents of the text.
제3도는 열처리 온도와 페라이트 분율과의 관계를 나타내는 그래프, 제4도는 열처리 온도와 브리넬 경도와의 관계를 나타내는 그래프이다.FIG. 3 is a graph showing the relationship between the heat treatment temperature and the ferrite fraction, and FIG. 4 is a graph showing the relationship between the heat treatment temperature and the Brinell hardness.
