Mathematical Modeling of Heating and Strain Aging of Steel during High-Speed Wire Drawing

In this article, a mathematical model of the wire’s average temperature change in process multiple drawing on high-speed straight-line machines has been developed. The calculation results showed that wire during at speed up to 45 m/s could reach 400 °C. Deformation heating does not exceed 60 °C, and due sliding friction can 300 depending coefficient, which ranges from 0.05 0.15. strain rates under conditions modern 7000 s?1. Over course research, it was found there are no for occurrence dynamic deformation aging impurity atoms carbon, nitrogen oxygen. At same time, parameters drawing, created onset steel presence hydrogen atoms. Therefore, heat treatment pickling, is necessary exclude hydrogenation steel. It established order static prevent above 180–200
