Description
(54) СПОСОБ РЕГУЛИРОВАНИЯ ТЕПЛОВОГО ПРОФИЛЯ ВАЛКА(54) METHOD FOR REGULATING THE ROLL PROTECTION HEAT PROFILE
Изобретение относитс к области листопрокатного производства и может найти применение преимуп1ественно при прокатке рулонов на листовом стане.The invention relates to the field of sheet-rolling production and may find application mainly in rolling coils on a sheet mill.
Известен способ регулировани теплового профил валка путем регулировани рас .чода о.хладител , причем в качестве исходного командного сигнала в системе регул.ировани принимают температуру валка и плос остпость прокатываемой полосы 1.There is a method of controlling the heat profile of the roll by adjusting the races of the coolant circuit, and the roll temperature and the flat strip of the rolled strip 1 are taken as the initial command signal in the control system.
Однако после устранени неплоскостности полосы тепловой профиль валков продолжает измен тьс за счет чроннкновепи тепла во внутренние слои валка, в результате чего возникает неплоскостность противоположного знака (например, волнистость переходит в коробоватость).However, after eliminating the non-flatness of the strip, the thermal profile of the rolls continues to change due to the chromonic heat in the inner layers of the roll, as a result of which the non-flatness of the opposite sign occurs (for example, waviness transforms into warpiness).
Цель изобретени - улучшение плоскостности прокатываемой полосы за счет упреждающего регулировани теплового профил валка .The purpose of the invention is to improve the flatness of the rolled strip due to proactive adjustment of the heat profile of the roll.
Цель достигаетс тем, что в качестве исходного командного сигнала дл системы регулировани расхода о.хладител принимают температуру рулона, измеренную перед его подачей на стан в двух точках его торцевой поверхности, расположенных на рассто НИИ , меньшем шага между витками максимальной телескопичности рулона.The goal is achieved by taking the temperature of the coil as the source command signal for the flow control system of the cooler fluid measured before it is fed to the mill at two points of its end surface located at a distance less than the pitch between the turns of the maximum telescopic roll.
Перед началом прокатки очередной рулон подката подают к разматывателю стана, гдеBefore the start of rolling, the next roll is rolled to the mill uncoiler, where
он в течение некоторого времени остаетс неподвижным, пока не закончитс прокаткаit remains motionless for some time until rolling is finished
предыдущего рулона. В это врем измер ют температуру неподвижного рулона с помощью термопары, подводимой к торцу рулона . Дл получени более точного результата измер ют в двух точках торцевой части рулона, расположенных друг от друга на рассто нии, меньшем тага между витками, максимальной телескопичности рулона (под шагом между витками максимальной телескопичности рулона понимаетс рассто ние между двум соседними наиболее выступающими витками рулона).previous roll. At this time, the temperature of the fixed roll is measured using a thermocouple fed to the end of the roll. To obtain a more accurate result, the two points of the end of the roll are spaced apart from each other at a distance less than the tag between the turns, the maximum roll telescopicity (by the step between the turns of the maximum roll telescopicity, the distance between the two most prominent turns of the roll).
