A Novel Technology for Microwave Heated Wire Drawing Process
Recent growth of modern industry requires multi-functional inorganic and micron-sized fibers.In this study,we suggested a novel method that could offer a high-efficient dieless drawing technology for manufacturing thin metal fibers based on the hot working principle.Microwave was used as the heat source.Experimental trials on a laboratory rig showed that the new system worked effectively and provided the feasibility in realizing the diameter attenuation up to 20 ％ diameter reduction.The theoretical model describing the wire deformation behavior in the working zone turned out to be in a good accordance to the experiment partly.Discrepancy in the hot zone near the exit could be attributed to the heat loss in the heat chamber.The coefficient of variation of the drawn wire diameter increased,as the draw ratio increased,which indicated that an ironing step would be needed to improve the evenness of the wire diameter.
