8KA.211.386中心导体以铸代锻工艺的探讨

Manufacture of 8KA.211.386 Central Conductor by Casting Instead of Forging

8KA.211.386中心导体是SF6高压开关设备中的一个关键零部件。原采用LD2铝合金锻造工艺制造,生产成本高,质量不能满足使用性能要求。通过试验研究,利用自行研制的ZDL2铸造铝硅合金,采用金属型低压铸造工艺,成功地制造出了成本低廉、性能优异、质量合格产品,保证了SF6高压开关设备的按期成套和及时交货。

8KA.211.386 central conductor is are one of key parts in SF6 high voltage apparatus.386 conductors were made from by LD2 forging Al alloy with forging process according.But the forging process for 386 conductor possesses many shortcomings such as long manufacturing period,high production cost,and low product quality.Through analysis and experiment the 386 conductors with cheap cost,excellent properties and satisfactory quality are successfully manufactured by self-developed ZDL2 casting Al-Si alloy and low-...
