Abstract
Abstract. Set earlier variational problem of rolling rails in the universal passes was implemented and solved in the MathCAD. Numerical implementation allowed determining the principles of metal forming in the maintenance of uniform deformation (the same reduction ratio) on all elements of the rail profi le. The dependences of the coeffi cients of side compression of head fl anges and base of a rail were determined, and of the coeffi cients of the increment and pulling-down of fl anges on the geometric parameters of the deformation zone and the friction conditions. These principles are described by engineering formulas to calculate indicated coeffi cients and they are the basis for scientifi cally based method of calculating rational scheme of reduction schedule and roll pass design for high-quality rails rolling on modern rolling mills.
