Radar technology in hot rolling mills

Technological advantages and decreasing costs are the reasons for the success of radar measurement systems for hot rolling mills. Contrary to light waves, radar radiation at the selected frequency range is insensitive to steam and dust. With high accuracies and robustness, the radar system works under harsh environmental conditions. Thereby, little maintenance and comparatively low investment costs are required. In the following, a first measurement system based on radar technology for width measurement in hot rolling mills will be presented.
