Description
РСзобретение относитс к электротехнике и предназначено дл автоматического управлени главными электроприводами клетей чистовой группы непрерывного, листового стана гор чей прокатки, снабженной подвижными eтлeдepжiaтeл ми, установленными в межклетевых промежутках и осуществл ющими регулирование нат жени и петли металла путем изменени скорости главных электроприводов.The invention relates to electrical engineering and is intended for automatic control of the main electric drives of the finishing groups of continuous, sheet rolling hot rolling mill equipped with mobile axles installed in the interstand gaps and adjusting the tension and the metal loop by changing the speed of the main electric drives.
Известно также устройство управлени главными электроприводами чистовой группы клетей, содержащее регул торы петли металла, выходы которых подключены через умножители к входам регул торов скорости всех петлей кроме средней, так называемой опорной :клети, пр чем регул торы петли Э межклетевых промежутках, рао оложенных до опорной клети, воздействуют на скорости клетей, предшествующих опорной а регул торы в промежутках за опорной-клетью - на скорости клетей, последующих по отношению к опорной Л.It is also known to control the main electric drives of the finishing group of stands, containing metal loop regulators, the outputs of which are connected through multipliers to the inputs of the speed regulators of all loops except the middle, so-called reference: stand, than the loop regulators E between interstand, spaced from stands, affect the speeds of the stands, preceding the reference and regulators in the intervals behind the reference stand — on the speeds of the stands, which follow relative to the reference L.
Как показывает-опыт эксплуатации, из-за неточного, подбора соотношени скоростей клетей регул торы нат жени As the operating experience shows, due to inaccurate, selection of the ratio of the speeds of the stands, tension regulators
и петли последних трех промежутков могут измен ть скорость последней клети на величину до 30%. Увеличение этой скорости ведет к образованиюскладок цолосы на отвод щем рольганге и преп тствует захвату полосы моталкой . Это приводит к тому, что необходимо устанавливать заведомо меньшую заправочную скорость, а это, в свою очередь, приводит к снижению производительности стана и уменьшению температуры конца прокатки, определ ющей физико-механические свойства проката, т.е. его качество.and the loops of the last three gaps can change the speed of the last stand by up to 30%. An increase in this speed leads to the formation of folds on the outgoing roller table and prevents the strip from being caught by the winder. This leads to the fact that it is necessary to set a deliberately lower filling speed, and this, in turn, leads to a decrease in mill productivity and a decrease in the rolling end temperature, which determines the physical and mechanical properties of the rolled metal, i.e. its quality.
