Description

где P - усилие прокатки; Q - усилие противоизгиба рабочего валка; F - усилие протнвоиэгнбг опорного валка; R - усилие дополнительною опорного валка; Mg, MI, М, М| - коэффициенты жесткости валковой системы на изгиб соответственно от усилий Р, Q, F, R. Дл  достижени  нулевого отклонени  профил  валковой системы должно выполн тьс  равенство Соотношени  С - Cf. определ ютс  а блоке 6 управлени  по сигналам датчиков . В этом же блоке заложены чисшнные значении коэффициентов жесткости М|,М|, Mj,Mjj, полученные расчетным илн экспериментальным путем. Регулирование усили  дополннтельного опорного валка позвол ет уменьшить усили  ре гулировани  протнвоизгиба рабочих и опорформула изобретени  Способ р€г.шров:ани  толщины полосы прк прокатке на широкополосных станах с oifsopными и рабочими валками посредством одновременного регулировайи  усилий противоизгиба рабочих и опорных валков от сигнала усили  прокатки, который раздел ют на два пропорционально соотношению усилий изгиба соответственно рабочих и торных валков, равному 0,3-0,4, отличающийс  тем, что, с цепью уменьшени  усилий регулировани  изгиба валков , дополнительно прикладыввкгг регулируемое уснлне к свободной части бочки опорного валка, пропорциональное соотношению усилий изгиба рабочих н опорных валков в зависимостн от ширины полосы. Источники информации, прин тые во внимание при экспертизе: 1.Патент Великобританнн № 1196155, кл. в 3 М, 1970. 2.Авторское свидетельсгао СССР М 435018, кл. В 2J В 37/02, 1973.where P is the rolling force; Q - the force of the bending of the work roll; F is the force of the backup roll support roll; R - additional force support roll; Mg, MI, M, M | - stiffness coefficients of the roll system for bending, respectively, from the forces P, Q, F, R. To achieve zero deviation of the profile of the roll system, the Ratio C - Cf should be equal. are determined in the control unit 6 by sensor signals. The same block contains the numerical values of the stiffness coefficients M |, M |, Mj, Mjj, obtained by calculation or experimentally. Adjusting the effort of the supplementary support roll reduces the effort to regulate protivoizgiba workers and the formula of the invention. Method of shir: the thickness of the strip prk rolling on broadband mills with oifsopornymi and work rolls by simultaneously adjusting the forces of the bending of the work and supporting rolls from the rolling force signal, which is divided into two proportional to the ratio of bending forces, respectively, of the working and beater rolls, equal to 0.3-0.4, characterized in that smoothing the rolls, additionally applied adjustable to the free part of the barrel of the support roll, proportional to the ratio of the bending forces of the workers to the support rolls depending on the width of the strip.
