METHOD FOR TREATMENT OF RAIL HEAD SURFACE Russian patent published in 2010 - IPC E01B31/13 E01B31/17 

FIELD: construction, road engineering.

SUBSTANCE: invention relates to method for treatment of rail head surface under conditions of rail track with application of rail-treatment trains. Method includes installation of treatment tools at various sections along and across the rail with displacement relative to each other. Treatment tools move along the rail and rotate around their axes. Axes are located in cross sections of rail so that working end surfaces of treatment tools, which are perpendicular to axes, are tangential to rated guide of rail travel surface. Speed of treatment tools relative to displacement along rail makes at least one tenth of optimal speed of rail material cutting. According to the method, in process of rail treatment in curved sections, frequency of tool rotation that works in inner loop of rail track is increased up to the value determined from the following expression: n₂=√91.28[((πn₁r/30)²+v² _n)-v² _n(R-H/R)²]/r², where n₂ - frequency of tool rotation working in inner loop of rail track, n₁ - frequency of tool rotation, working along outer loop of rail track, r - tool radius, v_n - speed of rail-treatment rain motion, R - radius of curvilinear section along axis of symmetry of rail track, H - width of rail track.

EFFECT: improved quality of rail head treatment in process of rail-treatment trains operation.
