Forward slip in rail profile rolling in universal caliber

Abstract

The previously stated variational problem of rail rolling in universal calibers is realized in the MathCAD software system. Numerical implementation permitted to establish regularities of forward slip changes depending on principal technological parameters of rolling. Dependences of the forward slip coefficient on the draft ratio of the rail profile web, the equivalent diameter of horizontal rolls, the equivalent flange thickness and friction conditions on contact surfaces are presented. Established regularities permitted to refine the model of the speed mode of rail rolling in modern rail and structural mills.
