摘要
在冲天炉熔炼条件下 ,研究了SI/C值对灰铸铁抗拉强度 ,弹性模量和硬度等铸铁质量的影响 .结果表明 ,在一定的碳当量CE的条件下 ,高的SI/C值的铸铁具有高强度、高刚度特性 .应用这种“双高”铸铁于S110 0机体生产 ,其铸造性能和机加工性能优良 .
In this paper,we research the influence of the ratio of Si/C on iron's strength,elasticity modulus and hardness in cupola's melting.The result shows that in certain carbon equivalent (CE),the iron with high ratio of Si/C has the property of high strength and high rigidity.The iron with “two high”,being produced in the S1100 diesel engine's body,would have good qualities of castable and machinable.
