概述了大型厚壁球墨铸铁件的国内外生产情况、研究方法，着重论述了这种铸件的质量控制（包括抗衰退性能控制、凝固时间控制、凝固方式控制）。还简述了大型球铁铸件质量控制研究的新发展。
The production situation and research methods of large-scale thick-walled ductile iron castings at home and abroad are summarized. The quality control (including anti-recession performance control, solidification time control and solidification mode control) of the castings is emphatically discussed. It also briefly introduces the new development of quality control of large ductile iron castings.
