FIELD: metallurgy.
SUBSTANCE: it is implemented the first rails strengthening by forces, directed in vertical plane. It is moved rail from area of the first strengthening on the naturally formed metre α to horizont. Rails is turned in vertical plane in opposite corner α direction by additional forces and it is implemented following strengthening of rail by forces, directed in horizontal plane. Rail turning in vertical plane in opposite corner α direction is implemented for value of angle, equal to (0.4…1.7)×α. Rail strengthening by forces, directed in horizontal plane, is implemented on the metre to horizontal for the rest angle value (-0.7…+0.6)×α. Additionally it is used rail-straightening complex, consisting sequentially installed horizontal roller leveler, vertical roller apron, bottom bending roller, top bending roller and vertical roll straightener.
EFFECT: there are improved rails and reduced bending roller wear.
