METHOD FOR HEAT TREATMENT OF RAILWAY SOLID WHEELS Russian patent published in 1995 - IPC

Abstract RU 2044072 C1

FIELD: ferrous metallurgy. SUBSTANCE: wheel is heated up to 600-650 C with holding for 3-6 h. During holding, wheels are subjected to single cooling down to 500-540 C at the rate of 2.0-2.5 C/min. Subsequent heating of wheels to initial temperature is effected at the rate of 3.5-4.0 C/min, and, then, subjected to final cooling. EFFECT: higher efficiency. 3 tbl
