序言在大力推广应用新材料的今天,铸铁已逐渐成为旧材料的典型。为此,最近几年来,人们都在努力开发铸铁的新功能,从而形成了各种铸铁新材料。例如c/v石墨铸铁虽然不具有象球墨铸铁那样的高强度和高延展性,但它却足一种良好的耐热材料,并且有良好的铸造性、高的导热率、低的热膨胀系数、低的拉伸弹性模具等特点,因此这种材料已作为耐热铸铁应用于工业生产之中。材料的
Preamble In the promotion of the application of new materials today, cast iron has become the typical old materials. To this end, in recent years, people are working hard to develop new functions of cast iron, resulting in a variety of new cast iron materials. For example, although c / v graphite cast iron does not have the same high strength and ductility as ductile cast iron, it has a good heat-resistant material and has good castability, high thermal conductivity, low coefficient of thermal expansion, Low tensile elastic mold and other characteristics, so this material has been used as a heat-resistant cast iron in industrial production.
