Description
This paper presents the technological parameter characteristics of casting and rolling processes (temperature distribution, strains, kinematics of rolling process) of ETP grade copper. It includes analysis of the influence of cathode chemical purity on structure and mechanical properties of wire rod, as well as detailed analysis of the results of research concerning correlation of wire heat resistance after 40% straining and the atoms of impurity elements. The paper focuses on the influence of these factors on mechanical properties and the energy state of wire rod.
