The order for this 200 tonne Ring-Rolling Mill commenced at the start of 1998, that included the design, manufacture, installation and commissioning. The mill hot-rolled hi-spec. alloy steel rings used in aerospace and similar industries. The rolling process reduced the wall thickness whilst at the same time refining the grain structure and minimising machining wastage.
John Davis was the Mill designer and David Giles the primary site installation and commissioning engineer.
This order was the last major-value machine built in Gloucester before closure in 2003.
The mill, the hydraulic power packs and electrical panels were erected in Gloucester in positions replicating their final locations on site, hence the height in building and the extensive scaffolding required. Good to have available a tall building and a 100 tonne crane!
This collection of approx. 80 images charts the final erection of the Ring-Rolling Mill in the New Fitting Shop; transportation of the mill from Gloucester to Blaenavon on 19/20th February 1999, including an overnight stop at Ross-on-Wye; arrival and offloading; internal movement onto prepared foundations and, finally, initial commissioning.
