Influence of copper fineness to wire mechanical properties at wire forming

Abstract

A production technology of copper products is based on melting of refinery and residual materials in pit furnace with following converter process. Converted copper together with the copper scrap material forms a batch of a tilting refinery furnace. This pyro-refinery process produces copper anodes that are further refined in electrolysis to copper cathodes. The high-grade copper cathodes are then processed by the continuous casting and rolling line to the copper wire with diameter of 8 mm.
