Geometric quantities of rolled products can be measured on-line in the manufacturing process using laser measurement technology. Examples of laser inspection systems, which are in routine use in rolling mills, their performance and the operational experience will be discussed. One- to three-dimensional geometric quantities are measured such as the thickness of cold rolled sheets, the cross sectional profile of rails and flatness defects of heavy plates. The features of the laser method will be compared to those of conventional measuring methods. Precision and measurement capability achieved under production conditions will be discussed.
