Efficient control of width and cutting coordinates to minimise waste
Our width and shape control solutions are optical, laser and vision-based — sometimes standalone, sometimes combined. They represent the state of the art in non-contact width and shape control on hot and cold strip and slabs, and on long products such as billets and pipes.
Dimensional control of width and shape is critical for downstream processing: it provides immediate information on non-conformity and supports waste-optimisation decisions. The system is widely used during the process to determine perfect cutting coordinates and communicate them promptly to shears and online cutting systems. Advanced analytic software (AAS) gives access to a wide range of information that drives quality optimisation.
