Automation of hot rolling mills

The combination of fast technological controls with precise physical-mathematical models for pass schedule calculation enables high throughput with the highest quality requirements. Modular concepts offer the possibility to modernize individual plant sections up to the entire plant.

Level 1 solutions

  • width control
  • thickness control
  • flatness control
  • loop control
  • down coiler control (side guides, pinch roll, wrapper roll)
  • speed control
  • actuator controls (roll gap adjustment, roll bending, roll shifting)
  • general control systems and sequences from furnace discharge to coil transport
  • roll change
  • media and lubrication systems

Level 2 solutions

  • physical matematical models (online, offline)
  • powerful network, data and application environment (libraries for mathematical operations etc.)
  • reporting (production, downtimes, quality)
  • visualization and data handling

Automation of cold rolling mills

Prior to the final finishing steps such as annealing, galvanizing, coating, etc., the cold rolling mill places particularly high demands on the tolerance, strip flatness and error free strip surfaces. The combination of modern control technologies with the physical mathematical models for the setting of the rolling mill are therefore of particular importance.

Level 1 solutions

  • thickness control
  • flatness control
  • tension controls for entry area, intermediate stand area and exit area
  • speed control

  • coil feed and coil removal
  • shearcontrol

Level 2 solutions

  • physical mathematical models (online, offline)
  • powerful network, data and application environment (libraries for mathematical operations etc.)
  • reporting (production, downtimes, quality)
  • visualization and data handling

Upgrades of existing automation systems

The IT industry is characterized by constant and extremely rapid development in the hardware and software technologies used. This also affects the automation systems used in the industry. Depending on the automation components (PC/server components, PLC components etc.) the life cycle is between 5 and 15 years. pa-innovations supports upgrades for different systems.

  • Upgrades from VANTAGE systems to the latest hardware based on embedded systems (VANTAGE was used by the former VAI in the area of technological controls)
  • Upgrades from DEC Alpha-based Level 2 Systems (VMS) to Windows based systems by virtualizing or transferring the code.
  • Upgrades from SIMATIC controllers to the latest software versions
  • Functional upgrades by using models based on the latest technological know-how

Integration test in the test field before delivery

The software created by us is subject to careful testing procedures. For this purpose, the automation hardware is set up in the test field. Various test cases are carried out, ranging from module tests to individual function tests to tests in the interplay of the individual plant sections. In addition to the application software, the automation systems are also tested with regard to CPU load and availability in continuous operation.

  • long-term test of the used hardware
  • functional test with simulation
  • training for maintenance engineers
  • training for operator
  • getting to understand the basic theoretical knowledge
  • practical exercises in the test field
  • Carrying out practical exercises in the test field


pa-innovations offers extensive training for maintenance engineers and operators. From the theory of the mechanical kinematic relationships and the resulting solutions of control engineering, training in the practical use of the application software and fault analysis to the training of the control personnel regarding operation and diagnosis.

  • theoretical principles as a prerequisite for the automation of the process
  • basics of the used programming tools
  • structure of the application software
  • diagnosis and fault analysis
  • operation and visualization
