Rolling of rail profiles in a universal groove. Part 2

Steel in Translation Aims and scope

Abstract

MathCAD software is used to solve the variation problem formulated in part 1 regarding the rolling of rail in universal grooves. On that basis, the laws governing the shaping of the metal in obtaining uniform deformation (with the same reduction coefficient) over all elements of the rail profile may be established. The dependence of the lateral-reduction coefficients of the flanges at the head and base of the rail blank are determined, along with the dependence of the flange increment (shrinkage) on the geometric parameters of the deformation region and the frictional conditions. The corresponding formulas are derived and used in calculating the best reduction conditions and roller groove configuration in the production of high-quality rail on modern mills.
