Abstract
СПОСОБ РЕГУЛИРОВАНИЯ СКОРОСТИ ВРАЩЕНИЯ РОЛИКОВ ОТВОДЯЩЕГО РОЛЬГАНГА ШИРОКОПОЛОСНОГО СТАНА ГОРЯЧЕЙ ПРОКАТКИ, включающий вращение роликов отвод щего рольганга электродвигател ми посто нного тока с независимым возбуждением, причем общее напр жение электродвигателей роликов , согласовано со скоростью последней прокатной клети, о т л и ч а ю щ и йс тем, , с целью увеличивани т нущей способности ролика и уменьшени его износа путем уменьшени проскальзы&ани ролика относительно транспортируемой полосы, напр жение на обмотку возбуждени электродвигат тел каждого ролика увеличивают в момент начала транспортировани полосы , обеспечива равенство скорости вращени ролика и скорости транспортируемой полосы, и дальнейшим его увеличением скорость электродвигател уменьшают и электродвигатель перевод т в генераторный режим,, когда окружна скорость ролика меньше поступательной скорости транспорти (Л руемой .полосы и ток кор электродвигател мен ет свой знак.METHOD FOR REGULATION OF SPEED ROLLERS out table BROADBAND hot rolling mill comprising rotating rollers diverter roller conveyor motor E DC with independent excitation, the total voltage rollers electric motors, in accord with the speed of the last roll stand of t n and h and w u and In order to increase the bearing capacity of the roller and reduce its wear and tear by reducing the slip and ampoule of the roller relative to the conveyed strip, the voltage applied to the winding is The excitation of the motor of the bodies of each roller increases at the moment of the start of transportation of the strip, ensuring equal speed of rotation of the roller and the speed of the transported strip, and further increasing it the speed of the electric motor is reduced and the electric motor is transferred to the generator mode when the circumferential speed of the roller is less than the translational speed of the transported (Leu. the strip and the current of the electric motor changes its sign.
