球墨铸铁工业生产60年的发展

60 Years Fast Development of Nodular Iron Industrialized Production

介绍了球墨铸铁60年来在产量、球化理论、球化剂及球化处理工艺、热处理技术等方面的发展情况,以及各种球化剂及球化处理工艺的特点。认为球墨铸铁由于有生产工艺简单、性能稳定、价格便宜等优点,因此目前仍在不断发展。

An introduction was made to the development situation of nodular cast iron in past 60 years in its output,theory on the nodular graphite formation mechanism,nodularizing alloys and nodularizing treating process,heat treating process,etc.and the characteristics of various nodularizing alloys and nodularizing treating processes.It s considered that at present,since having advantages of simple production process,stable properties,cheap price and so on,the nodular cast iron is developing continually forward.
