散热器有气密性要求

精铸生产有一定难度。对铸件的结构进行了详尽的分析

从浇注系统设计、充型速度、型壳的浇注温度、钢液过热度等方面分别提出了相应的工艺措施

从而改善了铸件的气密性能

减少焊补

提高铸件成品率。

It is difficult to cast the radiatior with air-tightness requirements in investment casting.Through analysis of structure of the radiator

some countermeasures

including design of gating system

filling velocity

pouring temperature of shell mold

super-heating of liquid steel

were conducted to improve the air-tightness of radiator and to decrease welding-repair

increasing the qualified rate of the investment casting radiators.
