Slab dimension / position measurement and tracking Improved process stability and reliability Transparency of input quality Minimized scrap and efficient material release processes Quality assurance of the slab casting process

Slab dimension / position measurement and tracking ‒ EMG iSCAN® Customer challenges: Precise measurement of width, length & thickness Further information of the width profile during casting process Harsh environmental conditions Wedge, camber, bending and chamfers of real slabs EMG solution: Width, length and thickness – EMG iSCAN® is your solution for hot strands and slabs. The precise and non-contact slab dimension measurement is performed with a customer-based arrangement of laser-based sensors. Even under great heat, our sensors keep a cool head. Therefore, ideally suited for harsh...

Improved process stability and reliability Performance features: Calculation of the minimum, maximum and average width Skew correction of the slab on the roller table Calculation of the slab wedge Measurement up to 2,200 °C material temperature Wavelengths of 405 nm and 670 nm available Different measurement ranges available Application-based selection of the best sensor type and configuration Stabile measuring technology and cooling concept for Tamb. > 45 °C Calculation of cold dimension of the strand or slab based on temperature model and pyrometer Implementation of customer-based...

Transparency of input quality Product types: thickness measurement width measurement Laser safety class (acc. to IEC) Wave length Technical data: Measuring accuracy* Ambient temperature Material surface temperature Power supply Ethernet, Profinet, Profibus *typically for standard applications (width) (thickness) (length) (temperature)

Minimized scrap and efficient material release Customer benefits: Length, width and thickness measurement on the hot strand or slabs under harsh environmental conditions Display of the slab width profile, for instance, gutter formation, edge shape and off-corner cracks Optimization of the casting process by the customer, for instance, change of the coquille setup, primary and secondary cooling Slab dimension measurement on the roller table to perform a efficient reheating process Calculation of a virtual rectangle of the slab to determine the optimal space inside the furnace Precise pushing...

Quality assurance of the slab casting process Protection and cooling housing: Protection and cooling housing: For the minimization of dust deposition on the laser optic or for cooling at ambient conditions > 45 °C it is possible as an option to protect the sensors with special housings.
