A cold rolling mill is part of the steelmaking process. It is used to roll steel ingots into thin sheets. The cold rolling mill consists of a series of rolls that are pressed onto the metal under pressure. This process compresses the molecules of the metal and reduces the thickness of the metal. The compression makes the metal stronger and it can then be cut into various shapes and sizes.
The environmental conditions require a robust embedded system with an IP67 protection class. Due to the different material thicknesses and fluctuating height positions, the height position of the measuring edge must be included in the calculation. The corresponding measurement data is transferred via network. The control data for a web guiding system is transferred via a Profi Net interface in order to additionally realize a web guiding system.
Two identical embedded systems operate in stereo mode. Due to a sophisticated exposure control, it is possible to work in reflection mode. Depending on the bandwidth, the system can be scaled. Connected with Ethernet, the cameras work independently and transfer the measured values to the master system. With an appropriate calibration template and routine, the system is calibrated on the machine over the entire width in 3D space.
