Abstract
Engineering formulas for the basic technological parameters when rolling I beams in universal grooves are derived on the basis of the variational principle of minimum total power. Those parameters are the increment and reduction of the flanges; the contact pressure at the horizontal and vertical rollers; and the rolling forces and torques.
