FIELD: process engineering.SUBSTANCE: invention relates to metallurgy an may be used for making steel section from continuously-cast billets. Proposed method comprises multipass reduction at vertical and horizontal rolls with cogging-down passes. Note here that reduction in the first two-four passes is performed at mismatched angular velocities of rolls that make aforesaid cogging-down pass of 2-8% and drawing factor in the pass making 1.2-1.5.EFFECT: expanded range of rolled stock.1 tbl, 1 ex |
