Abstract

A method of rolling billets of continuously cast steels includes deformation of slabs in the direction of larger axis of symmetry of liquation zone on the smooth barrel in several passes during the first stage, subsequent deformation in the multipass caliber with shaping of cavities of trapezoid form in the middle part of the faces, which contact with the rolls, and concentration of liquation zone in the middle part of the billet at the second stage. At deformation during the first stage the passes with rolling on smooth barrel and passes with shaping of cavities with width of base equal to the width of liquation zone, with depth of 0.05-0.75 of the height of breakdown of up to the pass and angle of the slope of lateral face of 15-55° alternate. Rolling on smooth barrel is performed with 20-30 % relative reduction.
