六十年来我国铸铁材料的发展

摘要

我国是铸造生产大国,2010年铸件年产量已近4 000万吨,连续11年位居世界首位.铸造新材料,新技术不断得到推广和应用,铸件质量逐渐提高,我国的铸造业正在向铸造强国挺进.本文简要论述了铸铁材料的发展历程、现状以及未来发展趋势.详细介绍了我国在灰铸铁、球墨铸铁、等温淬火球墨铸铁(ADI)、蠕墨铸铁、可锻铸铁以及特种性能铸铁方面的发展及应用情况,并指出了未来的发展方向.%With the promotion and application of new foundry materials and technologies, the castings' quality has been improved gradually. This paper presents the development history, status and tendency of cast iron. Hie development and application of cast iron in China, including gray cast iron, ductile iron, austempered ductile iron, vermicular cast iron, malleable cast iron, as well as cast irons with special performance, were introduced in detail, and the development direction of cast irons was pointed out.
