  • Robust Tension Control of Strip for 5Stand Tandem Cold Mills

    Tandem cold rolling process is a nonlinear complex system with external and internal uncertainties and significant disturbances. The improvement in the quality of the final output depends on the control strategy of centerline thickness and interstand tension. This paper focuses on interstand tension control problem in 5stand tandem cold rolling mills.

  • Looper and tension control in hot rolling mills: A survey

    Looper and tension control is important in hot strip mills because they affect the strip quality as well as strip threading. Moreover, the most difficult challenge in controller design and control

  • Tension Load Cell Web Tension Control System

    By using a load cell sensor and load cell amplifier with other equipment, you can create a tension control system that automatically keeps controlled tension on material, on a roll, in a manufacturing process. Now that you know a little more about tension load cell technology, take a look at some of the options from Comptrol.

  • What is a Load Cell and how does it work OMEGA

    A load cell (or loadcell) is a transducer which converts force into a measurable electrical output. Although there are many varieties of force sensors, strain gauge load cells are the most commonly used type. Except for certain laboratories where precision mechanical balances are still used, strain gauge load cells dominate the weighing industry.
