wires and for railway contact and catenary wire applications. The patented pulse motion control offers users the ability to alter and adjust the casting sequence and speed according to the alloy and rod diameter being produced. Optimal settings can be stored in the PLC memory to ensure consistent production parameters from cast to cast. Rautomead will also be promoting its patented RSL sealed lid continuous casting technology, designed for processing progressive alloy rods such as copper chrome zirconium for subsequent manufacture of welding tips and small-diameter drawn wires. The fully enclosed furnace features multiple independently controlled feed mechanisms that deliver cored wire and CuOF rod to the furnace to match the melting casting output rate while maintaining precise alloy composition.

The system then regulates a closed PID loop, controlling output pressure to individual nitrogen nozzles. With a bed of fine aluminium oxide particles and precise air and gas control, QED’s fluidbed furnaces are claimed to offer an environmentally friendly heat-treating solution in an energy efficient package. The fluidbed’s rapid heat transfer results in shorter furnace length and more compact and easier-to operate process lines.

In the challenge was to straighten and cut high speed steel from 8 to 14mm and achieve a rate of 80m/min. The use of rotating cutters was not possible due to the requirements for cut quality. Ravni Technologies instead developed a linear flying shear. The cut is performed between two accurate cutting dies, which avoids any deformation. At wire 2024, Ravni will exhibit a standard MDC20 straightening and cutting machine, an MCH40 chamfering machine and a new MGR60 mesh cutting machine. Ravni Technologies www.ravni.com Redies Deutschland GmbH 09 B17 Redies Deutschland GmbH, acting for all Redies sites, has in recent years been looking for a suitable replacement for natural diamond (ND) in drawing tools. There are several reasons for replacing natural diamond with something synthetic. Natural diamonds are – by nature – subject to deviations in composition, shape and purity. However, customers rely on consistency in quality of their tools. With natural diamond this has been achieved through a very strict selection of the available crystals. developing the machine,

HighTurbulence™ pickling system

The addition of pulse-firing technology to QED’s muffle tube austinitising furnace improves the thermal efficiency and increases temperature uniformity, owing to 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 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. The HighTurbulence™ pickling system optimises fluid flow to break down the static boundary layer surrounding the wires and rapidly remove scale. With multiple cascading stages, the system lowers acid consumption and minimises waste treatment requirements. 10 B56 Rautomead will be introducing its new RIC 400 model break-ring, continuous casting technology, which has been developed to process cobalt alloy, nickel alloy and iron alloy wire rods from 2.5 to 50mm diameter. The company will also present its RS range of graphite furnace continuous casting machines for the manufacture of extra-low oxygen content CuOF rod and for the production of high-quality conductor alloy rods such as CuMg, CuSn and CuAg for signal data transmission QED Wire Lines Inc www.qedwire.com Rautomead Ltd

Break-ring casting

Sample coils for any of the above materials can be manufactured to order and produced on continuous casting equipment installed at Rautomead’s facility in Dundee, UK. Rautomead Ltd www.rautomead.com Ravni Technologies 10 B04 The MDC60-CVL is a straightening and cutting machine launched by Ravni Technologies in 2023. It is equipped with a numerically controlled flying shear that accommodates special and hard material.

SSCD and ND side by side (bearing diameter 150µm)

In addition, the individual natural diamond is not completely traceable from its mining location to the end user. This is accompanied by a lack of comprehensive pricing by suppliers. Recent international conflicts and trade restrictions are fuelling an increase in prices, which begins to show its effect on the prices of finished wire dies. Redies has tested producers and suppliers in recent years and has collaboratively developed a product that can be offered to customers, without caveats. SSCD (synthetic diamonds) statistically have a higher degree of purity and more consistent quality than natural diamonds (ND). The height and diameter of the SSCD are chosen such that equal crystal volumes are delivered with the drawing tool.

Ravni will exhibit its straightening, cutting and chamfering technology
