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.
