Rautomead’s new RDG series up to 30,000 tpa
Continuous casting technology specialist Rautomead has introduced a new range of copper rod casting machines that it says “represent a significant leap forward in copper rod production”.
Combining the advantages of graphite furnace technology all in a single melting, holding and casting furnace, the new machines – branded as the RDG series – have rated outputs from 10,000 to 30,000 tonnes-per-annum (tpa) combined with “impressively low operating costs”.
The design of the machines is the result of close technical collaboration between Rautomead – with its specialist knowledge of continuous casting systems – and Induga, German specialists in induction heating. Both companies have over twenty years’ experience in their respective fields.
Available in 10,000–12,000 tpa and 18,000–20,000 tpa capacities – all without the need for hot metal transfer – RDG machines feature automatic cathode feed, a single channel-type induction furnace with separate melting and holding baths, multiple-strand casting stations, super-cooling design and withdrawal technology, plus five-tonne capacity rod coilers.
The RDG-360 machine for 30,000 tpa features a primary melting furnace transferring liquid copper through an enclosed channel into a holding and casting furnace, complete with Rautomead continuous casting withdrawal, tooling, controls and rod coiling units.
Alumina linings are used in the induction furnace, and graphite technology is used in the holding and casting chamber for conditioning the molten copper prior to casting. A state-of-the-art Siemens PLC control and monitoring suite provide the operator with a full picture of process status and sequences at all times, with automatic data-logging and complete traceability.
Commenting on the new series Rautomead Chairman, Sir Michael Nairn, said: “Our customers now enjoy even greater flexibility of choice. Large-scale CuOF rod producers have gained the opportunity to purchase a single Rautomead model capable of meeting their entire annual manufacturing requirement. Alternatively, for smaller manufacturing quantities, or for the production of a range of different copper alloys, customers may decide to invest in a single or multiple 6,000 tpa resistance-heated RS series machine.”
