Ross & Catherall’s and CAPI’s air melt departments operate numerous air induction melting furnaces allowing them to offer customers a wide range of yield weights from 500 to 2,300 kg (1,102 – 5,070 lb). A comprehensive range of iron, nickel and cobalt based alloys can be produced either to individual customer requirements or to internationally accepted specifications as required.
The production of airmelted superalloys involves a fully automatic metal mould casting machine delivering moulds to two pouring stations. By utilising two stations, overall pouring times are reduced to a minimum ensuring close control of chemistry throughout the heat. The transfer of molten alloy from the furnace to the moulds is achieved by the use of teapot ladles.
The coated metal moulds ensure a high standard of barstock surface finish. A typical open bar poured weight is 3 to 5 kg (6.6 – 11 lb) but varying bar weights from approximately 2.5 up to 6 kg (5.5 – 13.2 lb) can be poured to suit the customer’s individual requirements.
All airmelted ingots are shotblasted, individually inspected and marked before packing and dispatch.
