IMS Measuring Sytems in Hot Rolling Mills

A key element of modern steelmaking is the production of hot-rolled strip. About 50% of the steel produced in the hot rolling process is processed into steel strips. Accordingly, not only maximum throughput and high availability are required from the mills, but also products with optimal material properties with exact geometries. For the production of flat products, hot strip rolling is one of the most productive solutions, offering the highest level of production and a wide product mix with excellent quality. Throughout the entire manufacturing process, precise control and regulation mechanisms, in conjunction with a higher-level process computer, ensure compliance with the tightest thickness, width and temperature tolerances over the entire length of the strip. The most important regulating instance within this closed-loop control is a high-precision measuring technology that immediately reports tolerance deviations in the running process to the Automatic Gauge Control (AGC) and Automatic Flatness Control (AFC) and thus has a direct influence on the fully automated readjustment of the rolling stands. Hot rolling mill operators of • continuous casting plants • casting / rolling mills • hot rolling mills • heavy plate and Steckel mills benefit worldwide from the large number of optimally coordinated IMS measuring systems for the precise determination of all relevant measured variables within the entire strip production process such as: • slab dimension • width • crop length • speed • length • thickness • thickness profile • temperature • flatness • 2D / 3D surface inspection • coil state measurement Precision technology that guarantees exact measurement results even under the most adverse environmental conditions such as heat, dirt and moisture and stands out for its impressive service life.
