大断面QT600-3球铁件的生产技术
Production Process of Large Section Castings of Ductile Iron QT600-3
摘要
Abstract
In order to get stable production of large section ductile iron QT600-3 castings, through adjusting production process and reasonable controlling chemical composition, and using crystal recarburizer to increase the nucleation in liquid iron, using mixed RE spheroidizer and long-life composite inoculant in the mode of ladle, floating silicon and metal-stream inoculation, the large section ductile iron QT600-3 castings with qualified microstructure, mechanical properties and product quality can be obtained.关键词
