FIELD: plastic working of metals, possibly manufacture of articles with elongated axis. ^ SUBSTANCE: method comprises steps of heating initial blank and feeding it to rolling stand; controlling temperature in position of starting deformation; shaping article in predetermined temperature range; then removing article from rolling stand and realizing additional temperature control of blank while deforming blank after removing it from rolling stand; measuring value real temperature range of rolling process; comparing said temperature range with predetermined value; then increasing and(or) decreasing heating temperature of initial blank in limit of predetermined temperature range depending upon change value of temperature range of rolling process. Deformation rate at cross-taper rolling is changed in range 28-150 m/min according to temperature change of rolled blank. ^ EFFECT: improved quality of rolled products, prevention of possibility of opening cavity in axial zone. ^ 2 cl, 2 dwg |
