Изобретение относитс к прокатном производству.The invention relates to rolling production.
По основному авт.св. №500819 известен способ прокатки заготовок, по которому перед прокаткой в многоручьевом калибре на кромках основных граней исходного сл ба формируют, например, с помощью вертикальных валков выступы шириной , перекрывающей , по крайней мере, ширину крайних ручьев совмещенного калибра.According to the main auth. No. 500819, a method for rolling billets is known, by which before rolling in a multi-gauge caliber on the edges of the main faces of the original slab, for example, using vertical rolls, projections with a width that overlaps at least the width of the extreme streams of the combined gauge.
Недостатками известного способа вл ютс наличие сложной привалковой арматуры дл симметричной задачи раската в первом пропуске и ухудшенные услови захвата.The disadvantages of the known method are the presence of complex privalovy armature for the symmetric problem of roll in the first pass and the deteriorated conditions of capture.
Предлагаемый способ прокатки заготовок отличаетс тем, что дл улучшени условий захвата выступы формируют под углом, равным, углу наклона наружных граней крайних ручьев , многоручьевого калибра.The proposed method of rolling billets is characterized in that in order to improve the gripping conditions, the protrusions are formed at an angle equal to the angle of inclination of the outer faces of the extreme streams, multi-gauge.
На чертеже дл иллюстрации описывыемого способа показаны кгшибр и исходна заготовка в первс пропуске где 1 - исходный сл б с выступами; многоручьевой калибр; 3 - угол In the drawing, to illustrate the described method, a kgfr and initial blank in the first pass are shown, where 1 is the initial lug with bosses; multi-gauge; 3 - angle

HaivioHa выступа; 4 - угол наружной грани многоручьевого калибра.HaivioHa protrusion; 4 - the angle of the outer face of the multi-gauge caliber.
Пример. Отливают сл бы из свинца размером 50x103x400 мм. Сл бы прокатывают в вертикальных калиброванных валких с углом выпуска 45 с целью формировани выступов под углом наклона наружных граней многоручьевого калибра. Дальнейшую прокатку производ т в трехручьевом квадратном калибре за п ть пропусков до перемычки междузаготовками1 мм. В результате было установлено, что услови захвата улучшаютс и наблюдаетс самоцентровка раската в вгшках с многоручьевыми калибрами.Example. One would cast a lead of 50x103x400 mm. The rolls would be rolled in a vertical, calibrated roller with an outlet angle of 45 in order to form the protrusions at an angle of inclination of the outer faces of the multi-strand caliber. Further rolling was carried out in a three-arm square caliber for five passes to the web between the workpieces 1 mm. As a result, it was found that the gripping conditions are improved and self-centering of the peal is observed in vgs with multi-baring gauges.
