环形喷嘴的熔模精密铸造
摘要
通过对环形喷嘴的生产实践
发现对于环形复杂薄壁零件
前两层采用硅溶胶粘结剂型壳
加固层采用水玻璃粘结剂型壳
同时采用离心铸造的方式
离心机转速控制在300r/min左右
可以浇注出完整的叶片
叶片表面质量好
达到了用户的要求。
Abstract
The actual production from ring nozzle in investment castings indicates that for complex ring thin-walled parts
initial two layer of solidified shell use sol silicate and enhanced layer adopts sodium silicate. Centrifugal casting at the pouring velocity within 300 r/min
meeting the requirements of the customer
can produce the ring nozzle with complete blade and good surface quality.
