The paper presents the technological possibilities and quality assessment of copper recovered from post-cable waste from end-of-life motor vehicles. Copper alloys, used for the production of electrically conductive conductors, were recycled. The copper fraction, separated by eddy currents from the polymer fraction, was tested. In order to determine the purity of the copper alloy obtained in the recycling process, the raw material was subjected to melting in a resistance furnace. Then the chemical composition of the recycled raw material was analyzed using a spectroscopic method, which determines the quality of the alloys, including mechanical and technological characteristics and the possibility of their reuse in foundries. The liquidus and solidus temperatures of the melted copper alloy were determined on the basis of the cooling curve by the Differential Thermal Analysis method (ATD). The tests were extended to the study of the material's microstructure, which was carried out on metallographic scrap to determine phase separations. Finally, the proportion of recovered copper alloy with a main element concentration of 98.78%, the weight of the scrap and the loss of material relative to the weight of the charge were determined.

摘要

The paper presents the technological possibilities and quality assessment of copper recovered from post-cable waste from end-of-life motor vehicles. Copper alloys, used for the production of electrically conductive conductors, were recycled. The copper fraction, separated by eddy currents from the polymer fraction, was tested. In order to determine the purity of the copper alloy obtained in the recycling process, the raw material was subjected to melting in a resistance furnace. Then the chemical composition of the recycled raw material was analyzed using a spectroscopic method, which determines the quality of the alloys, including mechanical and technological characteristics and the possibility of their reuse in foundries. The liquidus and solidus temperatures of the melted copper alloy were determined on the basis of the cooling curve by the Differential Thermal Analysis method (ATD). The tests were extended to the study of the material's microstructure, which was carried out on metallographic scrap to determine phase separations. Finally, the proportion of recovered copper alloy with a main element concentration of 98.78%, the weight of the scrap and the loss of material relative to the weight of the charge were determined.
