Description
(54) СПОСОБ УПРАВЛЕНИЯ СКОРОСТЬЮ НЕПРЕРЫВНОГО МНОГОКЛЕТЕВОГО СТАНА ХОЛОДНОЙ ПРОКАТКИ(54) METHOD FOR CONTROLLING THE SPEED OF THE CONTINUOUS MULTICELLULAR COLD ROLLING MILL
ка кор двигател клети, соответствующее величине зоны нечувствительности блока (10 или 12), то на выходе этого блока но вл етс сигнал, соответствующий превыщению сигнала задани (сумма сигналов 14 и 4) над допустимой по услови м работы привода величиной . Сигнал с выхода блока зоны нечувствительности 10 или 12 поступает на вход задатчика скорости 1 и измен ет его выходной сигнал 14 таким образом, чтобы значение скорости и тока кор данной клети остались допустимыми; это изменение сигнала 14 поступает на вход остальных клетей и мен ет дл них задание скорости в направлении, обратном поступившему сигналу 4, и в такой мере, что разность скоростей клетей 2 и 3 по величине соответствует величине сигнала 4. Таким образом обеспечиваютс требуемые величина и темп отработки сигнала технологическогоAs the motor cage of the stand corresponds to the value of the dead zone of the block (10 or 12), then the output of this block is a signal corresponding to the excess of the reference signal (the sum of signals 14 and 4) over the value allowed by the drive conditions. The signal from the output of the dead zone unit 10 or 12 is fed to the input of the setpoint speed 1 and changes its output signal 14 so that the value of the speed and current of the core of this stand remain valid; This change in signal 14 is fed to the input of the remaining stands and changes the speed reference for them in the direction opposite to the incoming signal 4, and to the extent that the difference in speeds of the stands 2 and 3 corresponds in magnitude to the signal 4. process signal processing
регул тора, включа случай работы какой-либо клети с максимально допустимой скоростью или максимально допустимым током.the regulator, including the case of operation of any stand with the maximum allowable speed or the maximum allowable current.
Предмет изобретени Subject invention
Способ управлени скоростью непрерывного многоклетевого стана холодной прокатки, оснащенного электроприводами клетей с регул торами скорости и тока двигателей и технологическими регул торами, воздействующими па регул торы скорости, отличающийс тем, что, с целью повыщени эффективности регулировани , управл ющее воздействиеThe method of controlling the speed of a continuous multicell cold rolling mill equipped with electric drives of stands with speed and current controllers and process controllers acting on speed controllers, characterized in that, in order to increase control efficiency, the control effect
на одну любую клеть от ее технологического регул тора при достижении максимально допустимых величин скорости или тока кор этой клети передают на регул торы скорости остальных клетей с обратным знаком.one of any stands from its technological regulator, when the maximum permissible values of speed or current are reached, the core of this stand is transferred to the speed regulators of the other stands with the opposite sign.
