Description

Иаобретенвв относ тс  к прокатному прошжюдству, в частности к прокатке полоссюой и ластовой стали.The invention relates to the rolling industry, in particular to rolling strip and flipper steel.

Известеи способ регулировани  тОлшнны   орОфвл  полосы, вкпючак аий пршюжение расшир юпщх усв  Л к шейкам апи подушкам вейакз/в, щтчвы усили  протнвоизгиба пиклически измеи ют во времени с переменны в фуи зви толщины полосы насп-отой flj. .Limes The method of regulating the mass of the OROFVL strip, inserting the aperture of the expansion of the muscles to the neck of the pillows of the weavers / in, the force of the protrusion is pyclicly measured in time with the variables in the fui zvi of the strip thickness flj. .

.- введенне колебани  в очаг деформа1Ш1 в вертикальной нлоскости не значительно снижает 5 трени  и усилие npoKaTira, а также ухудишет товарный внд поверхиости проката..- the introduction of vibrations into the deformity of the Sh1SH1 in the vertical plane does not significantly reduce the 5 friction and force of the npoKaTira, as well as worsen the marketable surface of the rolled products.

Целью изобреггени   вл етс  снижение усили  прокатки неповышение качества проката.The aim of the isobregnation is to reduce the rolling force and improve the quality of the rolled products.

Достигаетс  это тем, «пч к бочкам валков прикладывают циклически измен ющиес  усили  в плоскости, параллельн Л вектору контактной силы трени  с относительным сдвигом фаз колебаний верхнего и нижнего валков,This is achieved by “applying cyclically varying forces to the roll barrels in a plane parallel to the vector of contact force of friction with a relative phase shift of the upper and lower rolls,

При подаче рабочей жидкости посто нного давлени  гидравлическими приводами в .гидравлических пульсаторах посто нное давление преобразуетс  в пульсирующее с переменной частотой, амплитудой и сдгом фаз колебаний. Пульсирующа  жидкость подаетс  в гидропилиндры, передава  колебани  упорным роликам, установленньгм на бочках валков, в плоскости, параллельной вектору контактной силы трени . В результате циклически i измен ющиесй усили  прикладываютс  к блочкам валков в плоскости, параллельной вектору контактной силы трени  с относительным сдвигом фаз колебаний. В этом случае происходит интенсивное снижение контактнсй силы трени  И уменьшение его подпнраюшегх действи  на усилие прокатки , которое снижаетс  в несколько раз по с известным способом. Кроме того, при колеба1ш х валков в плоскости, параллельны) вектору контактHcrfi трени , уменьшаетс  величина выступов на поверхности полосы.When the working fluid is supplied with constant pressure by hydraulic drives in hydraulic pulsators, the constant pressure is converted into a pulsating one with a variable frequency, amplitude and phase shift of the oscillations. The pulsating fluid is fed into the hydro-cylinders, transmitting vibrations to the stop rollers mounted on the roll barrels in a plane parallel to the vector of contact friction force. As a result, cyclically i varying forces are applied to the roll blocks in a plane parallel to the contact force vector of friction with a relative phase shift of the oscillations. In this case, there is an intensive decrease in the contact force of friction AND a decrease in its sub-action on the rolling force, which decreases several times in a known manner. In addition, when the rolls oscillate in a plane parallel to the friction contact Hcrfi vector, the amount of protrusions on the strip surface decreases.
