Beschreibung
Zusammenfassung:	The invention relates to the field of metallurgy, in particular to the methods for heat treatment of railway rolling stock parts, specifically railway rolling stock unit center plate. The center plate strengthening device contains a power coil and a sprayer, the power coil being implemented as turnable against the center plate central axis and containing a tube with spray cooling openings. The method for railway rolling stock unit center plate strengthening is performed by progressive induction hardening with simultaneous liquid cooling while rotating the center plate strengthening device 360° around the central axis where the center plate treated surfaces undergo induction heating, spray cooling immediately after the heating, and low-temperature volume tempering with a dwelling period.
