弹簧盒工艺改进

Improving the Casting Technology for the Spring Box

弹簧盒属于铁铬配件,技术条件要求较高并要求进行水压试验、通过对其工艺过程的总结,将为我们今后生产类似的薄壁、结构复杂、芯子难以固定的阀类件提供一个参考。

This paper summed up the experience of casting technology in producing railway-locomotive spare part spring box. which asked higher technical condition and hydraulic-press experiment. It will be a reference in future to deal with such sorts of valves castings that are characterized of complicated structure thin-wall.and have uneasy—fixed cores.
