FIELD: process engineering.
SUBSTANCE: proposed method relates to railway transport and may be used for reconditioning worn-out surfaces of car wheel rim by building-up. Proposed method comprises removal of worn-out flange and heating wheel rim to 200-250°C. Then, alloyed metal is built up on rotary wheel surface by means of crystalliser in electroslag hard-facing process using welding wire and flux with simultaneous built-up metal tempering. Crystalliser inner surface cross-section mates the profile and parameters of wheel standard rim. Building-up is performed parallel with wheel axis in direction from the flange at simultaneous rotation of wheel and crystalliser.
EFFECT: longer life, higher mechanical properties of flange working surface and wheel rim rolling surface.
