High-accuracy strip thickness control technology

  • This technology realizes stable feedback strip thickness control based on a law of constant mass flow.
  • The non-interference of the rolling force control system and tension control system between stands realizes plate thickness control without any disturbance.
  • The dynamic setup capability - enabling continuous changes in control target values in a transient state - will increase the accuracy of strip thickness control around welding points, thereby minimizing the off-gauge length.

High-accuracy shape control technology

  • Operations performed with the sophisticated information processing technology (e.g., neural net, fuzzy estimation, model base control) based on detected shapes can be used to control benders and spot coolants.
  • This control system is modeled based on the experience of skilled operators to realize precise, stable control.
  • The control rules are changed and the membership function is adjusted to facilitate functional expansion and fine adjustment.
