"BurrDetection" on steel slabs

When cutting steel slabs, there is a flow of slag which solidifies as burr on the underside of the slab. The removal of this burr is inevitable. The deburring system, however, may slip over the burrs which are sometimes extremely flat.

Currently used systems have not proven reliable for residual burr detection. The use of an innovative thermal imaging system, on the contrary, ensures residual burr detection after the slab-cutting process with 100% reliability:

• It ensures continuously high quality and avoids costly customer complaints.
• Accurate detection of temperature differences between slab and burr through use of 76,800-pixel high-resolution cameras
• Real-time display of image sequences and evaluation of temperature information in specific regions (regions of interest)
• Data transfer to a higher level control unit for removal of bad slabs from the process (using digital or analog output modules and TPC/IP protocols)
• Installation of camera system in a robust industrial enclosure with powerful air wiping to protect objective against high dust loads
