Disgrifiad

This photograph shows Aluminium Corporation Limited's works in Dolgarrog. The rows of housing in the background were built by the company for its workers and their families and was part of the facilities that had been constructed for workers by the company.In 1972 that housing was offered for sale to sitting tenants and from then housing in the village became more available to people not connected to the aluminium works.

The 80 foot bay extension referenced was required to hold the new Coiled Strip Rolling Mill installed in 1965. This was a Loewy-Robertson 60" wide 4 High prestressed constant gap mill which was the most modern strip mill in terms of gauge control at the time. In addition to the mill which allowed coils up to 650kgs in weight to be rolled directly from the Robertson 2 Hi hot mill, this extension included a GWB ( Gibbons Wild Barfield) electrically heated coil annealing furnace and charger. The larger coils also required a new 54" Robertson slitter to trim edge cracks, to split coils for coil fed blanking presses and to provide narrower coils for the older 2 high strip mills that produced box cap & seal sheet, and the substrate for Michelin tyre treads. The mill also required a Denco activated earth filtration plant for the Esso Somentor 37 rolling oil with its Wyrol 12 additive, which was fitted in an adjacent building.
