对日本卡亚巴灰铸铁、德国哈威蠕墨铸铁和意大利沃尔福球墨铸铁阀体材料进行了研究,利用OM、SEM、EDS分析了3种铸铁的微观组织特征,利用硬度计和万能试验机测试了3种铸铁的力学性能指标。认为3种铸铁可在不同工况下使用的液压多路阀阀体材料中选择和使用。
Japan Kaaba gray cast iron, Germany Hardway vermicular graphite cast iron and Italy Wolfowitz ductile iron body material were studied using OM, SEM, EDS analysis of the three kinds of cast iron microstructure characteristics, the use of hardness tester and universal test Machine tested three kinds of cast iron mechanical properties. That the three kinds of cast iron can be used under different conditions of hydraulic multi-valve body material selection and use.
