Measuring accuracy improved by a factor of ten

摘要

The material behaviour and mechanical dimensions of rolled aluminium must be constant over the complete length and width of strip within the tightest tolerances. Only in this way can the evermore exacting quality demands of downstream processors be satisfied. With the several thousand metres of strip material wound on to a coil involved, this is a challenge and requirement for manufacturers that can only be met by using measuring systems placed at significant points in the production process. Measuring systems that detect online – i.e. during the running process – and are equipped with an intelligent quality management and evaluation system for precise plant control. IMS Messsysteme in Germany has offered a variety of non-contact measuring systems for various measuring tasks in aluminium and other rolling mills since the 1980s. It builds systems for non-contact detection of thickness, thickness profile, width, wedge, coating, flatness and – most recently – also for surface inspection.
