Description

Известный стан дл  непрерывно-реверсивной прокатки, содержащий несколько последовательно установленных клетей с реверсивным приводом, имеет высокую стоимость главного привода.The known mill for continuous reversing rolling, containing several successively installed stands with reversing drive, has a high cost of the main drive.

Предлагаемый стан отличаетс  от известного тем, что его нечетные и четные клети объединены соответственно в две группы, причем клетн внутри группы снабжены синхронизированными механизмами подъема - опускани  клетей, а привод выполнен нереверсивным и дл  клетей разных групп противонаправленным; механизмы подъема - опускани  выполнены общими дл  каждой пары соседних клетей в виде параллелограммных коромысел .The proposed mill differs from the well-known one in that its odd and even stands are combined into two groups, respectively, and the cells inside the group are equipped with synchronized lifting and lowering mechanisms of the stands, and the drive is non-reversible and for the stands of different groups oppositely; lifting and lowering mechanisms are made common for each pair of neighboring stands in the form of parallelogram rocker arms.

Это позвол ет упростить привод, повысить производительность стана и упростить установку групп клетей под прокатку.This allows you to simplify the drive, increase mill productivity and simplify the installation of stands for rolling.

На фиг. I показан общий вид стана, главный вид; на фиг. 2 - лини  клети стана; на фиг. 3 - общий вид стана, в плане.FIG. I shows the general view of the camp, the main view; in fig. 2 - lines of the mill stand; in fig. 3 - a general view of the camp, in plan.

Предлагаемый стан состоит из четырех последовательно расположенных перемещающихс  в вертикальной плоскости нереверсивных клетей 1, сгруппированных поиарно, с приводом через щестеренную клеть 2 от электродвигател  3 с маховиком 4. Клети, составл ющие пару, соединены рычажным механизмом 5, который взаимно уравновешивает клети и обеснечивает их попеременное перемещение по высоте , т. е. поочередную установку калибров валков на уровень прокатки.The proposed mill consists of four successively located in the vertical plane irreversible stands 1, grouped poiarno, driven through a shchestrennaya stand 2 from the electric motor 3 with the flywheel 4. displacement along the height, i.e., alternately setting the roll gauges to the rolling level.

Рычажна  система 5 клетей вьшол.нена вLever system 5 cages

виде двух двуплечих рычагов - коромысел 6, которые шарнирно св заны с опорами 7, на которых установлены клети 1, и со стационарной , заделанной в фундамент опорой 8.the form of two two shoulders - rocker arms 6, which are hingedly connected with supports 7, on which stands 1 are installed, and with stationary support 8, embedded in the foundation.

Привод 9 механизма качани  выполненThe drive 9 of the swing mechanism is made

гидравлическим с механизмом регулировки 10 величины хода, фиксирующим крайние положени  клетей.hydraulic with a mechanism for adjusting the 10 stroke, fixing the extreme positions of the stands.

Рычажные системы обеих пар клетей дл  лучшей синхронизации их работы могут быть св заны дополнительными спарниками. Стан работает следующим образом. Металл при прокатке одновременно деформируетс  в двух клет х, наход щихс  в верхнем ноложении и имеющих одинаковое направление вращени  валков. При этом верхние валкн клетей, наход щихс  в нижнем положении, служат дополнительщ ми роликами рольганга , так как направление вращени  их верхней части соответствует направлению прокатки, иThe lever systems of both pairs of cages can be connected by additional steam guns for better synchronization of their work. The camp works as follows. During rolling, the metal is simultaneously deformed in two cages that are in the upper position and have the same direction of rotation of the rolls. In this case, the upper rolls of the stands in the lower position serve as additional rollers of the roller table, since the direction of rotation of their upper part corresponds to the direction of rolling, and

металл при движении опираетс  на них.the metal rests on them when moving.

При реверсировании направлени  прокатки соседние клети с помощью рычажного механизма 5 и привода 9 его перемещени  мен ют свои положени , обеспечива  деформацию проката в установленном направлении прокатки,When the rolling direction is reversed, the neighboring stands with the help of the lever mechanism 5 and the drive 9 of its movement change their positions, ensuring the rolling deformation in the established rolling direction,

.ибо направление вращени  вал,ков ,в каждой паре клетей выполнено противонаправленным.By either the direction of rotation, the shaft, coke, in each pair of stands is made oppositely.

Предлагаемый стан может быть использован в качестве обжимного или заготовочного при прокатке блюмов, малых слитков, литой заготовки, сортового и листового металла как в черной, так и в цветной металлургии.The proposed mill can be used as a crimping or billet when rolling blooms, small ingots, cast billets, graded and sheet metal in ferrous and non-ferrous metallurgy.

Стан обладает р дом преимуществ, основными из которых  вл ютс : больша  технологическа  гибкость благодар  возможности размещени  в валках большого числа калибров, возможность принудительной задачи проката во вторую по ходу прокатки пару валков, сокращение цикла прокатки.The mill has a number of advantages, the main of which are: great technological flexibility due to the possibility of placing a large number of gauges in the rolls, the possibility of forcing the task of rolling into the second pair of rolls during rolling, shortening the rolling cycle.

Рабочие клети предлагаемого стана могут быть выполнены с нажимными устройствами, в комбинации жестких клетей и клетей с нажимными устройствами, что позвол ет получать прокат высокого качества.The working stands of the proposed mill can be made with pressure devices, in combination of rigid stands and pressure stands with pressure devices, which allows to obtain high quality rolling.
