The Challenge of Modern Cold Rolling

In the competitive US steel market, cold rolling mills face a dual challenge: maintaining strict dimensional tolerances (thickness/flatness) while maximizing line speed. Traditional control loops often react too slowly to incoming strip variations, leading to off-gauge material at the head and tail of coils.

Technical Insight: AGC & Flatness Control

Modern Automatic Gauge Control (AGC) systems rely on millisecond-level data processing. By integrating hydraulic gap control with real-time X-ray feedback, operators can reduce thickness deviation by up to 40%. However, hardware alone isn't enough; the logic driving these actuators must be predictive, not just reactive.

The MK Codes Approach

Our solutions interface directly with Level 1 and Level 2 automation systems. We capture high-frequency data from load cells and tensiometers to predict roll deflection before it affects the strip. This allows for:

  • Dynamic Setpoint Adjustment: Automatically compensating for work roll thermal expansion.
  • Surface Defect Tracking: Mapping defects to specific coordinates on the coil for downstream processing.
  • Throughput Optimization: AI-driven speed ramping that avoids chatter vibration.
