Abstract
1. Устройство для правки широких горячекатаных полос, содержащее натяжные станции и пары правильных роликов заданных размеров, установленных между станциями, отличающееся тем, что натяжная станция перед роликами содержит два валка, а после роликов - четыре валка с S-образным огибанием их движущейся полосой, ролики I и II пар и верхний ролик III пары выполнены с одинаковыми диаметрами d0, равными 18,8…19,2 максимальной толщины выпрямляемой полосы, а нижний ролик III пары выполнен с диаметром D=(3,25…3,33)d0, при этом нижние ролики I и II пар смещены относительно верхних в направлении движения полосы на =(1,30…1,35)d0, а III пары - на =(3,27…3,29)d0, и расстояние между верхними роликами всех пар одинаковы и равны (4,5…4,7)d0. ! 2. Устройство по п.1, отличающееся тем, что все правильные ролики, кроме нижнего III пары, выполнены с опорными роликами. ! 3. Способ правки широких горячекатаных полос перед травлением, включающий знакопеременный продольный изгиб и растяжение металла и отличающийся тем, что при правке полос шириной В=1,03…1,83 м и толщиной h=1,5…2,99 мм ролики I пары устанавливают с перекрытием по вертикали δ1=(0,25…0,26)d0, II пара устанавливают с δ2=(0,29…0,30)d0 и III - с δ3=(0,20…0,21)d0, а при правке полос той же ширины В, но с h'=3,0…4,0 мм ролики I пары устанавливают с δ'1(0,24…0,25)d0, II пары - с δ'2=(0,28…0,29)d0 и III пары - с δ'3=(0,185…0,20)d0, при этом максимальная величина натяжения полос наибольшего поперечного сечения 4×1830 мм2 находится в пределах 900…950 кН.1. A device for dressing wide hot-rolled strips containing tensioning stations and pairs of straight rollers of a given size installed between the stations, characterized in that the tensioning station in front of the rollers contains two rolls, and after the rollers - four rolls with an S-shaped envelope with their moving strip, rollers of pairs I and II and the upper roller of the third pair are made with the same diameters d0 equal to 18.8 ... 19.2 of the maximum thickness of the straightened strip, and the lower roller of the third pair is made with a diameter D = (3.25 ... 3.33) d0, while the lower rollers of I and II pairs are shifted relative but the upper ones in the direction of the strip movement are = (1.30 ... 1.35) d0, and the third pair is = (3.27 ... 3.29) d0, and the distance between the upper rollers of all the pairs is the same and equal (4.5 ... 4.7) d0. ! 2. The device according to claim 1, characterized in that all the correct rollers, except for the lower III pair, are made with support rollers. ! 3. The method of editing wide hot-rolled strips before etching, including alternating longitudinal bending and stretching of the metal and characterized in that when editing strips of width B = 1.03 ... 1.83 m and thickness h = 1.5 ... 2.99 mm, rollers I pairs are set with vertical overlap δ1 = (0.25 ... 0.26) d0, II pairs are set with δ2 = (0.29 ... 0.30) d0 and III are set with δ3 = (0.20 ... 0.21) d0, and when editing strips of the same width B, but with h '= 3.0 ... 4.0 mm, rollers of the first pair are set with δ'1 (0.24 ... 0.25) d0, the second pair are set with δ'2 = (0.28 ... 0.29) d0 and III pairs - with δ'3 = (0.185 ... 0.20) d0, while the maximum tension of the strips of the largest cross section is 4 × 18 30 mm2 is in the range of 900 ... 950 kN.
