冷却环加工工艺改进

冷却环是一个直径较大，技术要求较高的复杂备件．在没有大型组装平台的情况下，从现有的设备、技术水平及冷却环的使用情况出发，对冷却环加工工艺予以改进，采用单元分组、整体拼装，一次加工组装达到技术要求．

Modification of the process for fabricating cooling ring

The cooling ring is a sophisticated part with a large diameter, which has to meet a relatively high technical specification. Without using any large-sized assembling platform, which was in fact unavailable at the plant, existing fabricating facilities and techniques, but with the fabricating process modified in which component units were first fabricated and then assembled into an integral ring, were employed to fabricate the cooling ring. The ring so fabricated could well meet the technical specifications.
