Tension control is the ability to maintain consistent and accurate tensile force on a product for repeatable defect free processing. To control a continuous length of web, cable, or wire along a machine requires the product to be kept "in tension" to manage and keep elongation as constant as possible. Tension control also keeps the product ...

In most well designed systems, the dancer roll will rise and fall in small increments constantly. In short. it dances! In a closed loop dancer unwind system there are several key components: The dancer itself, a feedback potentiometer, a control and the brake or drive. The goal in a dancer system is for the dancer to remain at the midpoint ...

In general, in a multispan rolltoroll system, a plurality of actuators and senor signals are provided in the tension control to handle tension disturbances between different spans, in particular the moment or speed of the end roller being controlled and measured. This is beneficial to improve the precision and robustness of tension control.

good open loop tension control. We would achieve a better result though if we could get some feedback from the achieved/actual tension. Closed loop control would use a dancer arm or load cell to measure the tension in the web. We make use of the fact that tension at the nip roll is the product of motor torque and the radius of the nip roll.

The eliminates operator dependency, and provides more accurate control of tension. Dancer System. Let's look at a typical dancer control system. In this system, the restraining torque is provided by a pneumatic brake, which is operated by a currenttopressure proportional valve, being controlled by the dancer tension controller.

Tension control is the process of maintaining a predetermined or set amount of stress or strain on a given material between two points to maintain its desired properties (such as form, appearance, etc) and quality. This process often takes place in specific control zones: unwind/payout, process (nip), and rewind/take up, with each having unique ...

The control in a dancer system interprets the feedback signal through a PID loop. It looks at the direction of change, amount of change, and rate of change. Based on these three variables, the control will adjust the force at the brake appropriately. A slow change in dancer position will result in a slow change in brake force.

Summary. Hot strip rolling mills are characterised by a process which has many interactions, is distributed with dominant transport delays and has a lack of measurements due to the severe environment. There is ever increasing market demand for better product quality of the steel strip hence the requirement for higher performance controllers.
