Wire rod from pearlitic steels and carbon content of 0.7-0.9 % is attributed to the responsible range of metal products, so its quality indicators are subject to very strict regulatory requirements. The results of research indicate that in industrial conditions there are all the necessary prerequisites for the effective impact of deformation-heat treatment on the processes of structure formation and ensure a more uniform distribution of structural components in the cross section of the wire rod. Increasing the average mass temperature increases the stability of austenite before the start of continuous cooling, and together with the lack of water cooling provides the formation of a more dispersed and homogeneous structure of wire rod of pearlitic grade steel.
