Rolling Mill Technology

Rolling Mill technology is a core competency of IMS. This is where IMS truly got its start, and remains at the heart of what we do. When it comes to Rolling knowledge and experience, IMS is a world leader. IMS was one of the first companies to pioneer the application of PLC systems to all aspects of rolling mill control. The concept from the beginning has been to use commercially available off-the-shelf solutions and reject “home brewed,” proprietary control system platforms.

No matter whether we are talking about hot mills, cold mills, plate mills, single stand mills, z-mills, tandem mills, reversing mills in steel, aluminum, titanium, and other metals – IMS has done that!

IMS brings vast experience with our own design algorithms to address the following sophisticated functions:

• Coordinated Strip Propulsion
  • “Smart” S-Ramp acceleration and deceleration
  • Speed bias cascading
  • Auto slowdown and stop with tail spot
  • Auto zoom for finish temperature control on hot strip mills
  • Inertia compensation for accel/decel
• Automatic Gauge Control (AGC)
  • Feed-forward
  • Volumetric (mass flow)
  • Gaugemeter
  • Thickness gauge feedback and monitor
  • Auto gain compensation for material hardness
  • Oil film compensation
  • Inertia compensation due to massflow corrections
• Automatic Flatness Control (AFC)
  • Shape Roll Interface
  • Bending control
  • Tilt control
  • Spray control
  • Crown control adjustments (Z-Mill applications)
