摘　　要：研究了D型石墨的数量及Si／C对金属型D型石墨铸铁在700～900℃范围内氧化速度的影响；对比了成分相同的D型石墨铸铁和A型石墨铸铁的抗氧化性能；探讨了金属型D型石墨铸铁的抗氧化机理，结果表明，金属型D型石墨铸铁具有优良的抗氧化性能。The influence of D - type grapI1ite count and Si/ C content on oxidizing rate at 7Oo ~ 9OOt of the D - type graphite iron cast in the permanent mould was investigated, the oxidizing resistances of the D - type graphite iron and the A - type graphite with same chemical composition were compared each with other, the oxidizing resistance mechanism of the D - type graphite iron cast in permanent mould was discussed. The results showed that the permanent mould cast iron with D - type graphite had excellent oxidizing resistance.
