Abstract:
In the production of reinforcing ropes, the patenting of wire rods is carried out under the technical production
regulations. Patenting is a consequence of isothermal treatment, in which the decomposition of supercooled austenite
is carried out in the lower part of the temperature range of diffusion transformation. In the microstructure of patented
steel, there should be no structures of prostate, bainite, and martensite. Such a structure has a combination of ductility
as well as good deformability with high reduction ratios. In the production of ropes, failure to comply with these
technical requirements can lead to serious consequences. The article examines the defects that have arisen in the
production of reinforcing ropes. In the course of the study, on the surface where the wires broke, uneven colors,
scratches, and small flaws were revealed. For microstructural analysis of the metal was used Microscope Altami
MET 1C. As a result of the microstructural study of steel, areas with large-lamellar perlite were identified, which led
to a wire break.
