Chinese producer selects Radyne

Radyne successfully completed the supply, installation and commissioning of induction heating equipment for six tyre cord diffusion (TCD) lines in China, each capable of running 24 wires at 80DV for wire diameters in the range of 1.1mm to 2.2mm. Delivered to a leading Chinese producer, each of the six lines included a pre-heat zone and a final heat zone, each supported by an IGBT power source, followed by two muffle temperature holding zones. The tyre cord diffusion process is carried out to prevent corrosion of wire within the tyre itself and to act as a lubricant for further wire diameter reductions in subsequent drawing operations. There are said to be many advantages and benefits associated with Radyne TCD systems, including high electrical efficiency and contact-less heating without the need to heat media such as sand. The system is operator friendly and includes a control system with a Siemens HMI that is an integral part of the IHWT has
