电磁负压充型工艺是在电磁充型低压铸造工艺的基础上发展而来的一种铸造技术,其充型能力强。相比传统的反重力铸造技术,该技术配合合适的浇注系统对铸件性能有明显的改善作用。通过分析其技术原理及特性,表明该技术更适合复杂薄壁铝合金铸件的生产,具有广阔的发展前景。
Electromagnetic negative pressure filling process is a kind of casting technology developed on the basis of electromagnetic filling low-pressure casting process, and its filling ability is strong. Compared with the traditional anti-gravity casting technology, the technology with a suitable casting system has a significant improvement on the performance of the casting. By analyzing its technical principle and characteristics, it shows that the technology is more suitable for the production of complex thin-walled aluminum alloy castings and has broad development prospects.
