Improvement of the technology for manufacture of billets of railroad wheels and hollow car axles, using intensive plastic deformation for effective rise of quality and functional properties of finished products, is the aim of this research. The paper presents the results of influence of deformation, which is realized via joint effect of rolling, reeling and consequent piercing, on mechanical properties of billets made of wheel steel of grade T. The rolling process in a three-roll mill is conducted via two passes with diameter reduction 20 % and elongation coefficient 1.56, while reeling in a two-roll mill is implemented with diameter reduction 12.5 % and elongation coefficient 1.31. Such deformation procedure creates the conditions allowing to increase strength and plastic properties of wheel steel and to form the structure in the central area of a deformed billet for consequent piercing. After piercing of preliminarily deformed billet, the properties of wheel steel stabilize significantly. When comparing the mechanical properties of wheel steel in the initial state and after deformation, the strength properties (σu, σ_0,2) increase by 1.6 times and plastic properties (δ, ψ) increase by 1.3 and 1.1 times respectively.

This research was financially supported by the Moscow Polytechnic University within the framework of the grant program named after Pyotr Kapitsa.
