摘要： The present disclosure relates to a welding base metal for recycling a railway wheel and a method for recycling a railway wheel using the same, which can overlay-weld a railway wheel with a welding base metal suitable for overlay-welding a railway wheel through a heat treatment, form a surface hardened layer, and strengthen the metal structure of the railway wheel, in order to recycle the railway wheel.
The welding base metal for recycling a railway wheel may be used as a surface hardened layer of a railway wheel because the welding base metal has high hardness while exhibiting a similar property to the railway wheel. Furthermore, the welding base metal can change the metal structure of the recycled railway wheel, and thus delay the initial wear time of the recycled railway wheel. The method for recycling a railway wheel may overlay-weld the damaged railway wheel to its original size, form a surface hardened layer, and change the metal structure of the railway wheel by changing the composition of the welding base metal and performing the pre-heat treatment and the post heat treatment, thereby minimizing the occurrence of damage to the recycled railway wheel.
