Изобретение относитс к метаппооб- работке и может быть использовано дл йроизводства холоднокатаных полос.The invention relates to meta-processing and can be used for the production of cold rolled strips.
Цель изобретени - повышение точности регулировани плоскостности полос ,The purpose of the invention is to improve the accuracy of controlling the flatness of strips,
На чертеже представлеиа ма, реализующа способ.In the drawing, an implementation method.
Прокатываема полоса 1 после выхода из валков прокатной клети 2 охватывает первую пару роликов 3, а затем - вторую пару роликов 4 и моталкой 5 наматываетс в рулон, причем оси роликов параллельны ос м прокатных валков и угол охвата каждого валка полосой составл ет 180 .The rolled strip 1, after leaving the rolls of the rolling stand 2, covers the first pair of rollers 3, and then the second pair of rollers 4 and the winder 5 is wound into a roll, with the axes of the rollers parallel to the axes of the rolls and the angle of coverage of each roll strip is 180.
В процессе прокатки необходимое нат жение полосы между прокатной клетью 2 и парой роликов 3 создаетс согласованным действием электроприводов (не.показаны) прокатной клети 2 и пары роликов 3, а между моталкой 5 и парой роликов 4 - согласованным действием электроприводов (не показаны ) моталки 5 и пары роликов 4.Ми62During the rolling process, the necessary tension between the rolling stand 2 and the pair of rollers 3 is created by the coordinated action of the electric drives (not shown) of the rolling stand 2 and the pair of rollers 3, and between the coiler 5 and the pair of rollers 4 - by the coordinated action of the electric drives (not shown) of the winder 5 and a pair of clips 4. Mi62
нимальное нат жение полосы на участке измерени , образованном парами роликов 3 и 4, поддерживаетс согласованной работой электроприводов указанных пар роликов.The minimum tension of the strip at the measurement site formed by the pairs of rollers 3 and 4 is maintained by the coordinated operation of the electric drives of the said pairs of rollers.
На поверхности измерительного стола полоса находитс практически без нат жени , что позвол ет измерить ее неплоскостность, характеризующуюс On the surface of the measuring table, the strip is practically without tension, which allows to measure its flatness, characterized by
величиной амплитуды и превышени участков полосы над поверхностью измерительного стола непосредственно.the magnitude of the amplitude and the excess of the strip sections above the surface of the measuring table directly.
Измеренна неплоскостность полосы устран етс путем воздействи на нажимные устройства, изгиб и охлаждение валков прокатной клети.The measured flatness of the strip is eliminated by acting on the pressure devices, bending and cooling the rolls of the rolling stand.
По сравнению с известными способами косвенного измерени неплоскостности полосы и регулировани этогоCompared with the known methods of indirectly measuring the flatness of a strip and regulating this
параметра, предлагаемый способ позвол ет измер ть неплоскостность полосы непосредственно в процессе прокатки и в величинах, которые установлены ГОСТом, и повысить точность регулировани плоскостности.parameter, the proposed method allows to measure the flatness of the strip directly in the rolling process and in values that are set by GOST, and to improve the accuracy of flatness control.
