摘要

高铬铸铁空心球阀的精密铸造难度较大

球阀内部必须空心、全封闭

同时高铬铸铁的裂纹敏感性极强。采用δ=2mm薄钢板经冲压、组焊形成球形金属芯代替水玻璃砂芯（或陶瓷芯）

成功铸造完成空心球阀阀体。

Abstract

It was very difficult for high Cr cast Fe hollow ball valve in investment casting due to its internal hollow and full close as well as high crack susceptibility.Hollow ball valve body was successfully produced in investment casting by using drawing-formed thin-walled steel sheet with 2 mm thickness ball core instead of sodium silicate core or ceramic core.
