EMG SORM 3plus - Online roughness measurement

Seamless measurement of production-relevant surface parameters

EMG SORM 3plus is the online measuring system for recording roughness parameters on running strips. An important quality feature of uncoated and surface-finished strips are roughness characteristics. The standard method used so far is roughness measurement by means of a stylus instrument.  

To do this, the operator must stop the production line or take samples from the coil and measure them offline in the laboratory. EMG SORM 3plus, on the other hand, is a non-contact online measuring system that can be used reliably on metallic and many non-metallic surfaces at production speeds of up to 2400 m/min.

"EMG SORM 3plus measures the metal strip online and calculates the surface profile, from which the roughness parameters Ra and RPc are then determined. Our solution thus enables the seamless measurement of production-relevant surface parameters."
