Central areas of application for series products, individual components and complex system solutions from EMG are continuous production processes in the metal industry. EMG’s innovative quality assurance systems enable you, as our customer, to continuously optimise your manufacturing processes and increase your production...

Online oil layer measurement EMG SOLID® is our system that is used for the online measurement of oil layers on running strip material. The typical application spectrum of EMG SOLID® ranges from the rolling mill, where the initial application of oil is implemented, to metal processors, for whom sufficient lubrication in the forming process and an oil-free surface before coatings or paintings are applied, are essential. Application fields By using EMG SOLID you can optimise your pressing and coating processes by assigning the quality features to the corresponding strip sections and/or sheet...

InfraRed spectroscopy LaserInduced Fluorescencespectroscopy Our solution EMG SOLID® IR is based on the infrared spectroscopy. The system emitts an infrared light that passes through the oil layer, is reflected from the strip surface and passes through the oil layer again. Via laser-induced fluorescence spectroscopy our system measures the coating weight of the oil layer and visualises it over the entire measured material surface: » Special solid state laser delivers 10.000 single pulses per second and excites the oil to glow In doing so the intensity of specific wavelengths of the oil layer...

Online measurement of tensile and yield strength EMG IMPOC is our tried and tested, magnetic-inductive measuring system for automatic, non-destructive online determination of the mechanical properties (tensile and yield strength) of ferroma-gnetic steel strip material. Areas of application include the production of cold-rolled and surfacecoated steel strip material, for example, in: » Hot-dip galvanising lines » Continuous annealing lines » Tinning lines » Continuous pickling lines* » Processing lines* *on request Online roughness measurement Roughness parameters are an important quality...

In hot-dip galvanising lines the zinc coating thickness is determined by air knives. This is where EMG eMASS®, our turnkey system for stabilising fast-running ferromagnetic steel strips based on electromagnets, is mainly used. EMG eMASS® optimises and economises the use of the metal coating at the blow-off nozzle of a hot-dip galvanising line for zinc coating, GALVALUME®* and aluminisation processes. In the area of blow-off nozzles the metal strip passing through the system is enlarged by so called “baffle blades” to avoid any form of air turbulence, which can lead to damage of the zinc...

Strip width measurement EMG BREIMO is our contact-free, optical strip width measuring system for steel strip material in continuously running processes. Consisting of a measuring frame with two sensor positioning devices EVK, the corresponding light emitters and a common linear stroke transducer, EMG BREIMO is an extremely reliable strip width measuring system. EMG BREIMO offers a robustness to external malfunctions. Changes to the strip edge position are continuously detected and taken into account when calculating and displaying the strip width. Online measurement of strip and slit strip...
