Some batches of production showed that microstructure of nodulariron in investment casting can reach to 2 grade nodularization, 6 grade nodule size and 10% pearlite.
经批生产考核,精铸球铁铸件的金相组织可达到球化级别2级,石墨球大小6级,珠光体含量10 %的要求。

Subsequently it is reliable for the proportional solidification theory to design feeding system of ring carrier casting of nodulariron.
实际证明:采用均衡凝固理论设计球铁圈形铸件的补缩系统是可靠的。

Material could be steel, stainless steel, aluminum, copper, nodularcastingiron and PA6.
