In cold rolling production, thickness accuracy is one of the most critical indicators of product quality. Whether you're producing automotive steel, stainless strip, electronic copper foil, or high-end aluminum sheet, consistent thickness is non-negotiable. The X-ray thickness gauge is the cornerstone technology that enables this level of precision.
Why Is the X-ray Thickness Gauge So Crucial?
-
Real-Time, High-Precision, Non-Contact Measurement
Using high-energy X-rays, the system detects material absorption differences to determine exact strip thickness, with accuracy up to ±1–5μm. -
Core Feedback for AGC Closed-Loop Control
The X-ray system feeds thickness data to the AGC system, enabling real-time roll gap adjustments to maintain uniform thickness throughout the coil. -
Higher Yield, Less Waste
Stable thickness control reduces edge scrap and defective products, saving material and energy costs. -
Meets Demanding Industry Standards
Sectors like auto body panels, battery foil, and surgical-grade stainless steel require strip thickness variation within ±2μm—only X-ray systems can reliably achieve this. -
Provides Crosswise and Lengthwise Monitoring
Generates live thickness maps for improved process tuning, roll wear analysis, and predictive maintenance.
Conclusion:
Without X-ray gauges, cold rolling relies on guesswork. With them, it becomes a data-driven, precision-controlled process. For any application demanding consistent gauge control, the X-ray thickness gauge is not just important—it’s the technological core of modern cold rolling.
