Rautomead Ltd

and uniform coating weight application with a precision of ±10g/m 2 . The measurement of galvanised coatings on steel wire is achieved via robustly designed sensors that communicate with a Siemens PLC control panel in real time. The sensors relay current coat weight data that is instantly compared to a user set target. The system then regulates a closed PID loop, controlling output pressure to individual nitrogen nozzles. The addition of pulse-firing technology to QED’s muffle tube austinitising furnace improves the thermal efficiency and increases temperature uniformity, owing to the higher average flame velocity and superior convective heat-transfer. Pulse firing also offers a higher turn-down ratio, lower NOx emissions and more flexibility in burner and zone control. QED’s latest wire-cleaning equipment is a dual-stage pre-cleaner with ultrasonic transducers. The precision laser-cut stainless-steel tank incorporates new temperature and level control features. Wires exit the cleaning section into a triple water rinse with four-stage suction wiping.

10 B56 Rautomead will be presenting its new model RS 3000SX continuous casting machine for the manufacture of extra low oxygen content CuOF rod. graphite furnace technology will produce low oxygen CuOFE (<5ppm) copper rod, which is suitable for most oxygen-free wire applications. However, technical requirements from the automotive industry are driving demands for even lower oxygen content copper rod, eg for use in the manufacture of high-efficiency bar-wound electric motors. The enhanced graphite crucible electric resistance furnace design of the RS 3000SX, combined with modified tooling and production techniques, improves the oxygen reduction capability of the graphite technology system to produce extra-low oxygen content copper rod. Rautomead will also be promoting its RSL sealed lid continuous casting technology, designed for processing progressive alloy rods such as copper chrome zirconium, together with its conventional open furnace models for producing high The company’s standard

purity oxygen-free copper wire rods and conductor alloy rods such as CuMg, CuAg and CuSn. This continuous cast rod material benefits manufacturers of bar wound motors, enamelled wires, superfine wires, LAN cables, wiring harnesses, railway wires, shaped, contact wires, CTC and transformer strips. Equipment is available for the production of 1,000 to 12,000 mt per year for products from 8 to 30mm in diameter.
