摘　　要：试验了合金元素钛以及铸型冷却条件对灰铸铁抗氧化性的影响,研究了石墨大小和D型石墨的含量对灰铸铁抗氧化性的影响。试验结果表明:石墨越细小,灰铸铁的抗氧化性越好; D型石墨铸铁的抗氧化性优于A型石墨铸铁。This Paper investigates the effects of the lengths of A-ype graphite and the per centages of D-ype graphite on the anti-xidizing properties of gray cast iron on the basis of the experiments of the variations of Ti content and the mold cooling condition. The experimental results show that the shorter the length of A-ype graphite,the more excellent the oxidation resistance of gray cast iron and the anti-xidizing property of D-ype graphite cast iron is much better than that of A-ype graphite cast iron.
