摘　　要：以大型球铁磨盘铸件为例,介绍了毛重95t球铁磨盘的生产过程,采用喂线法球化处理的铸件组织、性能及超声波探伤(UT)、磁粉探伤(MT)均满足技术指标要求,并实现稳定批量生产。生产实践表明,喂线法球化处理是保证大型球铁件质量的有效途径。The wire feeding production process of ductile iron grinding table with a gross weight ot 95 t was introduced. The microstructure and mechanical properties, ultrasonic and testing magnetic particle all meet the technical requirements of the casting. Meanwhile, mass production achieves with a steady quality up to now. The production practice shows that wire feeding process is an effective way to produce large ductile iron castings.
