Abstract
The new recycling technology for aged aluminum wires in overhead conductor have been carried out. We are attempting to develop remanufacturing method for them for more effective way of recycling in stead of its conventional remelting process. The drawing process of aged aluminum wires play a role in remanufacture process. Drawing process was performed under lubricant. The speed of drawing was between 500 m/min and 1,000 m/min. These machines have 11 or 12 dies house for breakdown of the feedstock. Material of the die is tungsten carbide and they have generally 25% reduction ratio. The paper investigates the mechanical properties during drawing process of aged aluminum wire. The results of tensile tests and microscopic analysis were discussed to underscore the hardening features of drawing aluminum wire. Various graphs are presented accompanied by discussion about their relevance on the process.
