METHOD OF TREATING RAILS Russian patent published in 1997 - IPC

Abstract RU 2084545 C1

FIELD: ferrous metallurgy. SUBSTANCE: rails subjected to volume heating, oil cooling, and drawback, are further subjected to at least one-step deformation, in the course of which water at 70-90 C is introduced at rate 0.5-1.5 l/min into deformation zone. EFFECT: decreased nonlinearity of rails with no change in the level of residual stresses. 2 cl, 1 tbl
