A width measurement system based on radar technology for hot rolling mills has been developed. A prototype system operating at 30 GHz was installed in the hot rolling mill of Salzgitter Flachstahl GmbH. During these tests, the high robustness and measurement accuracy under rough environmental conditions were demonstrated. Afterward, a 60-GHz system was developed. After field tests in the hot rolling mill, the system will be used for accurate width control at the roughing stand.
