We presented the results of scientific and practical investigations of the technology of rolling of asymmetric rail sections, namely, of point and wing rails, performed on a universal rail and structural steel mill. The detected disadvantages are described according to the initial calibration and the causes of formation of the surface defects in the course of rolling of these profiles are established. The results of the performed analysis made it possible to develop calibrations for the analyzed asymmetric rail sections with evaluation of the stressed state of the metal in the course of rolling.
