Claims (4)

1. Способ прокатки сортовых профилей из непрерывнолитых заготовок, включающий их нагрев в печи, гидросбив окалины и многократное обжатие в черновых проходах с вытяжными калибрами по системе «ромб-квадрат», отличающийся тем, что гидросбив осуществляют подачей плоских струй воды под давлением 20-30 ати на грани полос после обжатия в каждом черновом проходе с коэффициентом вытяжки 1,05-1,30, причем после первого прохода производят кантовку полос на угол 90°.1. The method of rolling varietal profiles from continuously cast billets, including their heating in the furnace, hydroscale of scale and multiple compression in rough passages with exhaust gauges according to the "rhomb-square" system, characterized in that the hydrocoupling is carried out by supplying flat jets of water under a pressure of 20-30 on the verge of strips after crimping in each draft passage with a drawing coefficient of 1.05-1.30, and after the first pass, the strips are turned over at an angle of 90 °. 2. Способ по п.1, отличающийся тем, что верхние по положению в печи стороны полос подвергают действию гидросбива после обжатия в каждом черновом проходе.2. The method according to claim 1, characterized in that the upper positions in the furnace side of the strips are subjected to hydraulic breakdown after crimping in each draft passage. 3. Способ по п.1, отличающийся тем, что плоские струи наклоняют под углом 75-80° к продольной оси полос.3. The method according to claim 1, characterized in that the flat jets are inclined at an angle of 75-80 ° to the longitudinal axis of the strips. 4. Способ по п.1, отличающийся тем, что сопла располагают на расстоянии 100-200 мм от соответствующей плоской стороны полосы.4. The method according to claim 1, characterized in that the nozzles are located at a distance of 100-200 mm from the corresponding flat side of the strip.
