SR耐热铸铁的研究

Research on SR Heat Resisting Cast Iron

本文应用正交试验法选定了SR耐热铸铁的最佳成份范围。结果表明,此种铸铁不仅耐热性能好。

In this paper, the most suitable composition range of SR heat resisting cast iron has been decided through orthogonal experiment. The experiments show that the heat resisting cast iron not only has achieved reguirements of heat resisting property, but also has little chilling tendency.
