Description

Известно устройство дл  автономного управлени  скорост ми вращени  валков клетей прокатного стана и автономного регулировани  межклетьевых нат жений -проката в непрерывном прокатном стане, содержащее .каиалы управлени  скорост ми валков клетей , включающие задатчик нат л ;ени , соединенный с регул тором скорости, блок умножени  и усилитель. Однако в известном устройстве задающее устройство определ ет соотношение скоростей двигателей, а не окрул ных скоростей валков, что затрудн ет работу оператора .при настройке -стана; кро.ме того, в регул торе -нат жени  требуетс  отдельный умножитель дл  получени  коэффициента усилени , пропорционального скорости стана, а сам регул тор не  вл етс  автономным. С -Целью повышени  точности управлени  и регулировани  в устройство введен измеритель отклонени  нат жени  от заданного, выход которого через усилитель соединен с рег}л тором скорости в канале управлени  скоростью, а вы.ход блока умножени  канала управлени  скоростью последующей клети подключен ко входу такого же блочка предыдущей клети. На чертеже изображена блок-схе.ма устройКлети / непрерывного стана (показано три клети) привод тс  в движение двигател ми 2, литаемы.ми от регулируемых преобразователей 3. Системы 4 управлени  приводом включают в себ  регул торы тока  кор  и скорости дв и ател , причем установка скорости задаетс  блоками 5 умножени . На входы блока умнол ;ени  клети поступают два сигнала: напр жение, пропорциональное установке скорости последующей клети, и напр лсение с выхода сумматора 6. На первый вход наир жение подаетс  через усилитель 7 с коэффициентом усилени , обеспечивающим приведение к окружной скорости валков, что позвол ет на второй вход умиолсител  подавать сигнал, пропорциональный выт лчке в последующей клети. Это значительно упрощает пастройку стана, так как оператор, первоначально устанавлива  с помощью задатчика 8 необходи.мые выт л ки, не дол леей прп этом учитывать, что редукторы клетей имеют разные передаточные чнсла, двигатели - разные нО|Мииальные скорости, а валки - разный диаметр. Кроме сигнала, пропорционального выт л ке , на вход сумматора 6 подаетс  еще сигнал с интегрального усилител  9 канала регул тора нат л ени  (уиравлеии  скоростью валков ), включаюи его кроме усилител  9 датчик 10 нат лсени  и сумматор 11 с зоной нечувстA device is known for autonomously controlling the rotational speeds of the rolls of the rolling mill stands and autonomously controlling the intercellular tensions of the rental in a continuous rolling mill, which contains control stands for the speeds of the rolls of the stands, including a natalizer; amplifier. However, in the known device, the driver determines the ratio of the speeds of the motors, rather than the circumferential speeds of the rolls, which makes it difficult for the operator to adjust when setting the -st; In addition, in a tension controller, a separate multiplier is required to obtain a gain proportional to the mill speed, and the controller itself is not autonomous. With the purpose of improving control accuracy and control, a tension deviation meter from the setpoint is entered into the device, the output of which is connected through an amplifier to a speed controller in the speed control channel, and the output of the speed control multiplier unit of the next stand is connected to the same input block of the previous cage. The drawing shows a block diagram of a device / continuous mill (three stands are shown) driven by motors 2, casting them from adjustable transducers 3. The drive control systems 4 include current controllers and speed controllers, moreover, the speed setting is specified by multiplication blocks 5. Two signals are sent to the inputs of the multiply stand cell: a voltage proportional to the speed setting of the next cage and the voltage from the output of the adder 6. To the first input, the voltage is fed through amplifier 7 with a gain factor that ensures At the second input of the monitor, it sends a signal proportional to the temperature in the subsequent stand. This greatly simplifies the mill installation, since the operator, initially installed using the setting unit 8, needed the necessary extractors, not to take into account that the gearboxes of the stands have different transfer gears, the engines - different NF | Miialnye speeds, and the rolls - different diameter. In addition to the signal proportional to the flow, the signal from the integrated amplifier 9 of the natures regulator channel (speed of rolls) is also fed to the input of the adder 6, switching on it, apart from the amplifier 9, the sensor 10 of the tension and the adder 11 with a zone nesuvst
