Abstract
Способ автоматического регулирования натяжения полосы в межклетевом промежутке широкополосного стана горячей прокатки, заключающийся в том, что при отсутствии прокатываемой полосы в межклетевом промежутке обеспечивают исходное положение петледержателя, соответствующее заданному начальному углу подъема, при заходе полосы в последующую (i+1)-ю клеть межклетевого промежутка осуществляют автоматический подъем петледержателя до момента его соприкосновения с полосой, после чего ограничивают угол подъема петледержателя и подают регулирующее воздействие на скорость двигателя (i+1)-й клети, обеспечивая подъем петледержателя до заданного рабочего угла, отличающийся тем, что, с целью повышения быстродействия регулирования натяжения, осуществляют одновременное корректирующее воздействие на гидравлическое нажимное устройство предыдущей i-й клети межклетевого промежутка. A method for automatically controlling the tension of the strip in the interstand space of the broadband hot rolling mill, which consists in the fact that in the absence of the rolled strip in the interstand space, the initial position of the loop holder corresponding to the given initial angle of rise is provided when the strip enters the subsequent (i + 1) -th stand of the interstand of the gap, the loop holder is automatically lifted until it comes in contact with the strip, after which the lifting angle of the loop holder is limited and served effect on the engine speed of the (i + 1) th stand, providing the loop holder to rise to a predetermined working angle, characterized in that, in order to increase the speed of tension regulation, they simultaneously perform a corrective action on the hydraulic pressure device of the previous i-th stand of the inter-stand gap.
