Project Details


Magnet wire machines apply coatings to the surfaces of copper wires by enamelling through specially designed nozzles. For the purpose of drying and hardening of the enamel layers, the wire is exposed to a hot air flow. The high temperature of the process air is mainly achieved by electrical heating. A part of the process air must inevitably be discharged directly after the catalytic burning of the solvent vapours, i.e. from the region of highest temperature, which causes considerable energy losses. Furthermore, the heat loss over the machine surface is significant. The aim of the project is the to reduce the energy demand of the machines. One starting point is a further improvement of process efficiency by optimization of heat and mass transfer at the wire surface. The minimization of flow losses will reduce the power requirement of aggregates. Innovative concepts for individual components will yield further reduced specific energy demand, and particularly the recovery of the inevitable hot exhaust air for system relevant secondary tasks seems promising.
