Abstract
The ideal material from the annealing susceptibility point of view should most of all be characterized by annealing kinetics which allow for a quick transition of materials from a hardened to a soft temper. This condition is possible to meet with copper of the lowest levels of impurities and also a correct structural state. These factors are ultimately formed in the continuous melting, casting and rolling lines. While the chemical composition of wire rods is ultimately modified with oxygen, the structural state of wire rods depends on the temperature and speed of the rolling and casting process. The elongation test within the tensile test of an adequately prepared wire (rapid tensile test - AR) is a method of determining the susceptibility of copper annealing. This method, apart from the classic spiral elongation test (SE) has come into permanent practice in the production of copper wire rods. As the susceptibility of copper annealing is closely connected with the amount and type of impurities, the above mentioned technological tests can to some degree be considered as an indirect measurement of the chemical purities of wire rods. Fundamentals of a new test AR, discussion with reference to traditional spiral elongation test and chosen research results will be main topic in this paper. This article presents the results of the simultaneous effects of the chemical compositions and the structural state of Cu-ETP wire rods on the results of annealing tests used until now (spiral elongation test, rapid tensile test) and also new propositions for alternative tests which allow for a quick Cu-ETP wire rod annealing susceptibility rating.
