东芝阀壳的铸造

Casting of TOSHIBA Valve Casing of C6-4. 9/0- 98 Steam Turbine

东芝阀壳是1.25Cr-1Mo合金钢铸件,质量要求高,铸造难度大。东方汽轮机厂在铸造过程的关键工序应用了多种新工艺、新技术,生产的铸件达到了设计的技术要求,为该厂分包国际公认的高难度铸钢件生产任务积累了经验。

TOSHIBA valve casing is a kind of 1. 25CrlMo alloy-steel casting which requires high-quality, and process of casting is very difficult. Many kinds of new technology and technical requirements of TOSHIBA specification are applied by Dongfang Steam Turbine Works in the key casting process, which accumulates the experiences for DFSTW to subcontract those high-difficult castings internationally.
