三、蠕虫状石墨铸铁的性能为了在生产中应用蠕虫状石墨铸铁,我们对它的性能进行了研究,测定了稀土镁钛蠕虫状石墨铸铁的一些机械、物理和铸造性能,并同合金铸铁、球墨铸铁进行了对比。结果表明,蠕虫状石墨铸铁的铸造性能优于球墨铸铁和合金铸铁,强度和合金铸铁相近,而塑性、疲劳强度和导热性能均优于合金铸铁,因此蠕虫状石墨铸铁具有良好的综合性能。
Third, the performance of worm-like graphite cast iron In order to use worm-like graphite cast iron in the production, we conducted a study of its performance, determination of some magnesium, titanium and worm-shaped graphite cast iron mechanical, physical and casting properties, and with the alloy cast iron, Ductile iron was compared. The results show that vermicular graphite cast iron has better casting performance than ductile cast iron and alloy cast iron, strength is similar to that of alloy cast iron, and plasticity, fatigue strength and thermal conductivity are better than alloy cast iron. Therefore, wormlike graphite cast iron has good comprehensive properties.
