EUROPEAN STEEL TECHNOLOGY AND APPLICATION DAYS 2017 - ESTAD 2017

A series of measurement systems have been developed by CRM during last years. This covers measurements from entry to exit of galvanising line. These measurements cover: oxide thickness measurement for oxydo-reduction control inside furnace, the shape of the strip inside furnace to control heat buckles, the position of wipers and the shape and vibrations of strip at bath level to control zinc coating homogeneity, characterisation of galvannealed product if produced, roughness and waviness systems to control the final product surface quality. All the measurements answer to the more and more high quality level requested by the customers. Highlights will be given on how to use these measurements, what is their precision and what are the advantages of each one for industrial lines.
