Abstract
Способ автоматического управления процессом прокатки в непрерывной группе клетей, согласно которому задают скорости предыдущей и последующей клетей межклетевого промежутка, измеряют ток двигателя предыдущей клети, до захода переднего конца металла в последующую клеть дополнительно осуществляют повышение скорости электропривода этой клети, осуществляют коррекцию скорости по запомненной последней скорости для оптимального приема следующей заготовки, отличающийся тем, что, с целью повышения устойчивости технологического процесса, дополнительно в установившемся режиме прокатки предыдущей полосы запоминают статическую просадку скорости электропривода каждой клети, возникающую за счет применения пропорционального регулятора скорости, повышение скорости электропривода последующей клети осуществляют при прокатке следующей полосы на величину запомненной статической просадки скорости в момент захвата полосы валками предыдущей клети, который определяют по возникновению статической составляющей измеряемого тока электропривода предыдущей клети.A method for automatically controlling the rolling process in a continuous group of stands, according to which the speeds of the previous and subsequent stands of the inter-stand space are set, the motor current of the previous stand is measured, before the front end of the metal enters the subsequent stand, the speed of the drive of this stand is additionally increased, the speed is adjusted according to the last stored speed for optimal reception of the next workpiece, characterized in that, in order to increase the stability of the process, d in addition, in the steady rolling mode of the previous strip, the static drawdown of the electric drive speed of each stand, arising due to the use of a proportional speed controller, is memorized, the drive speed of the next stand is increased by rolling the next strip by the value of the stored static drawdown speed at the moment the strip is captured by the rolls of the previous stand, which is determined by the occurrence of the static component of the measured current of the electric drive of the previous stand.
