摘要
结合深井用潜水泵导流壳体的结构特点及要求,采用中温蜡硅溶胶制壳工艺生产。通过在花边法兰设置补缩环、调整花边法兰及壳体中间芯部内浇道的高度、在型壳易裂部位开设排蜡孔、型壳内腔采用陶瓷型芯、底注后中间冒口再补浇、浇注后冒口散热面覆盖石棉等工艺措施,铸件品质完全达标。
Considering structural features and requirements of underwater pump discharge housing, middle-temperature wax was used for making sol silicate shell. Through adopting some technological, such as placing feeding ring on lacy flange , adjusting the flange’s position and height of ingate located inside housing, setting de-waxing holes at crack-easy location, using ceramic core in cavity of shell, re-pouring riser after bottom pouring as well as covering top surfaces of downsprue and riser with asbestos after pouring, the quality of the investment castings fully meet the requirement.
