The Impact of the Heat Treatment Parameters on Patenting Line on Mechanical-technological Properties of Steel Cord Wires

M. Suliga, R. Kruzel, Czestochowa University of Technology, Faculty of Production Engineering and Materials Technology, Czestochowa, Poland In the paper the influence of modification of patenting process on steel cord properties has been assessed. It was found that the wires of pearlite structure, in comparison to the wires of pearlite-bainite structure, characterized much better properties which is confirmed by higher tensile strength by more than 12 %, higher by 1,6 % the number of twists and higher by 3,6 % the number of bends. It was found that weaving steel wire cord causes a decline in its exploitation properties, which should be associated with an additional deformation of the wire in the cords manufacturing and the size of the decline depends on the type of wire structure.
