To produce the highest quality oxygen-free copper wire rod in a range of sizes from 8.0mm to 22mm diameter, a Vietnamese company has installed an automated upward vertical casting machine.
Advanced know-how ensures quality precious metals
Advanced conti-cast expertise, utilising a naturally oxygen-reducing graphite crucible and safe, low voltage resistance heating produces the very highest quality precious metals products.
The billets will then be used in a followi-on extrusion operation.
Cimini may also use the RT 650 produce flat products up to 6in (150mm) wide.
The RT 650 continuous caster uses a graphite crucible furnace with its naturally oxygen-reducing characteristics.
These characteristic makes the machine suitable for holding and casting of silver, which is otherwise very prone to oxygen pick-up in the molten state, said Rautomead.
Rautomead chairman, Sir Michael Nairn, said: "As an organisation that regularly sells continuous casting equipment on a global scale, it was nevertheless particularly rewarding to secure this significant order for the supply of a silver billet caster with a company in the United States".
Following delivery, a Rautomead engineer will commission the machine at the customer's works in USA.
* Continuous casting of bronze - Rautomead has also sold two horizontal continuous casting machines to Rapsri Engineering Industries, of Bangalore, India.
Rapsri produces of high quality bronze alloy bearings.
The two Rautomead machines - an RT 650 and an RMT 200 model - will enable Tapsri to expand the range of continuously cast alloys and product sizes.
* Copper rod caster - Rautomead has also lately won an order from Metalka Majur, of Serbia, to supply an RS 3000/6 upwards-vertical copper rod continuous casting machine.
The RS 3000/6 will be the fourth Rautomead copper rod casting machine to be installed in Serbia.
The RS 3000/6 model will produce high quality 8mm oxygen-free copper rod at a new cable manufacturing facility being established by Metalka at Jagodina, south-east of Belgrade.
Metalka manufactures a range of modern electrical switchgear and its move into cable-making is a major expansion for the company.
