摘　　要：针对球墨铸铁中石墨球粗大问题,本文提出用堆焊法来细化球墨铸铁表层石墨球。结果表明:用该方法可在球墨铸铁表层获得具有尺寸细小、圆整度好且分布均匀的石墨球。Aiming at coarse spheroidal graphite in nodular cast iron, spheroidal graphite in nodular cast iron surface layerrefined by welding method was presented. The results show that this method can be used to obtain spheroidal graphite withsmaller size, more rounded and uniform distribution in nodular cast iron surface layer.
