Project Background & Challenges

The modern metal processing industry faces multiple challenges, including increasing production efficiency, reducing energy consumption, improving product quality, and enhancing flexibility. Traditional hot rolling mills may suffer from aging equipment, outdated control systems, significant variations in product tolerances, and high energy consumption, which constrain the enhancement of corporate competitiveness. This solution aims to address these challenges by providing a complete package for the modernization of existing hot rolling mills or new turnkey projects.

Core Components of the Solution

Our solution is a comprehensive system integrating advanced technology, high-performance equipment, and full lifecycle services.

High-End Hot Rolling Mill Stands:

  • Utilizes high-strength, high-rigidity housings and precision roll chocks to ensure stability and accuracy during rolling.
  • Offers various mill configurations (2-Hi, 4-Hi, 6-Hi) to meet different process requirements from roughing to finishing.
  • Equipped with Hydraulic Automatic Gauge Control (HAGC) systems for precise and rapid roll gap adjustment, guaranteeing product thickness tolerance.

Advanced Automation & Control Systems:

  • A three-level automation system (L1 Basic Automation, L2 Process Control, L3 Production Management) based on PLCs and Industrial PCs.
  • Integrates intelligent algorithms like Model Predictive Control (MPC) and adaptive control for optimized and self-learning rolling processes.
  • Employs high-precision sensors (laser speedometers, thickness gauges, hot metal detectors, etc.) for real-time data acquisition and closed-loop control.

Efficient Auxiliary Systems:

  • Furnace Systems: Walking beam or pusher-type furnaces with optimized combustion control systems ensure uniform slab heating and minimal energy consumption.
  • Descaling System: High-pressure water descaling units effectively remove primary scale, improving surface quality.
  • Cooling System: Laminar cooling or Ultra-Fast Cooling (UFC) systems enable precise control of the product's microstructure and mechanical properties (TMCP process).
  • Coiling System: Downcoilers ensure stable strip coiling, forming neat coils.

Digitalization & Smart Factory Integration:

  • Provides Manufacturing Execution System (MES) interfaces for order management, production scheduling, quality tracing, and performance analysis.
  • Utilizes Industrial IoT (IIoT) platforms for equipment condition monitoring, predictive maintenance, and energy management, reducing unplanned downtime.
