The RE(Y)-Mg-Si-Fe nodularizer had been used to cast heavy sectioned high ductile nodular iron cooling wall castings.

应用钇基重稀土镁复合球化剂，铸造厚大断面高韧性球铁冷却壁，成功地获得了铸件中心部位铸态高性能。

The nodulizing power of the La-Mg nodulizer and its influences on the chilling sensitivity of nodular cast iron and the property of anti-degeneration were studied.

研究了镧镁球化剂的球化能力及其对球墨铸铁白口敏感性和抗衰退性的影响。
