CONFECÇÃO DE UM PROJETO DE RECOZIMENTO INDUTIVO DE FIOS DE COBRE

Abstract

The preparation of a project for induction annealing of copper wires is to circulate a high current in high frequency by a coil and the Lenz's law will circulate a current contrary to original heating the workpiece and is this the principle proposed in this work to replace the current annealing system that operates by joule effect , where the wire is placed in between two pulleys and runs an electric current between them by heating the wire. The current system presents many problems due to wear and tear suffered by the contact rings begin to mark the wire, these marks are not accepted by many customers because the product might fail later in other tests. The proposal to replace the current system offers many advantages because the system will work without contact. The cost for deployment of the system is high if purchased directly from manufacturers, but it is possible to reduce this cost by leveraging existing system, although the design for the recozedor by induction requires more specific electronic components not found in the domestic market being necessary. Some prototypes are being manufactured for design validation and testing in the field and have achieved good results.
