ABB launches new low-force system for ultra-thin metal strip applications

The new Stressometer Low-Force Flatness System enhances process control and yield, offering high accuracy and robustness in cold rolling mill applications.

ABB has launched an advanced low-force system for cold rolling mill applications. Aimed at processes producing ultra-thin metals including aluminum, copper and steel foils, the new Stressometer Low-Force Flatness System combines high accuracy with a robust design and a low total cost of ownership.

Fitted into a compact 200 mm diameter roll, the low-force system maintains the physical footprint of ABB’s standard Stressometer® sensor while integrating specialized material properties to detect extremely small force variations to within a few grams with unmatched resolution. This enables much tighter flatness, thickness and tension control in finishing applications handling foil gauges ranging from 50 down to five microns.

The Stressometer Low-Force Flatness System is ideally suited for finishing mills and integrated lines handling both breakdown and finishing passes. Its high performance enables precise control where standard force sensors become noisy or inaccurate, particularly below 20 microns. By ensuring consistently high quality, it enables producers to maintain high throughput whilst reducing scrap and re-processing.
