METHOD AND PLANT FOR CONTINUOUS PRODUCTION OF STEEL WIRE Russian patent published in 2016 - IPC C21D9/64 C21D9/54 C21D8/06 

FIELD: metallurgy.

SUBSTANCE: invention relates to metallurgy. To improve mechanical properties of the wire and provide a homogeneous microstructure the steel wire manufacturing method involves production of the steel wire, heating up to the steel wire austenitizing temperature, patenting the steel wire, drawing the steel wire. Patenting the steel wire includes slow cooling of the said steel wire from the austenitizing temperature down to the first preset temperature, fast cooling of the wire to the second preset temperature, holding the wire at the specified second preset temperature.

EFFECT: during the slow cooling the steel wire in fact retains its austenitic structure, at the subsequent fast cooling the steel wire is in better conditions to start a phase changing, wherein the austenitic structure is converted into a pearlite structure.
