摘要

总结了国外V法铸造发展的3个特征:①设备大型化和小型化并进;②在铸钢和球铁生产上优势凸显;③铝合金和镁合金铸件具有潜在优势;归纳出国内V法铸造技术上的5个突破:①EVA塑料薄膜实现系列化和标准化;②自主创新、拥有自主知识产权的大型V法造型线;③采用CAD/CAM技术、提升了V法铸件质量;④V法铸造真空系统的控制与节能技术;⑤在铸钢、球铁和铝合金铸件上应用获得突破

以及存在机械化程度不高、铸造环境差、V法铸造低碳不锈钢有增碳现象等问题。

Abstract

Three characteristics of V-EPC castings at home and abroad were reviewed

including co-development of large equipment and small equipment

the superiority in cast steel and nodular iron production as well as potential advantages in aluminum alloy and magnesium alloy product.Five technological breakthroughs of V-EPC at home were expounded including series and stadardization of EVA plastic film

development of large V-EPC molding line with independent intellectual property and independent innovation and improvement of V-EPC casting quality by means of CAD/CAM

control and energy-saving of vacuum system for V-EPC as well as application breakthrough of V-EPC in cast steel

nodular iron and aluminum alloy parts.However

there exist some problems

such as low machinery level

serious production circumstance and recarborization in low carbon stainless steel.
