Measurement of Coarse Wire in Steel Rolling Mills Using 2D/3D Profile Sensors

During the production of coarse wire in steelworks, billets up to 1,200°C must be rolled and then checked for geometric quality characteristics such as diameter, ovality, rolling or surface defects. There are specially developed measuring systems for this purpose that enable a 360° image of the wire in micrometer-precise resolution with four 2D/3D profile sensors each. In the profile sensors, which work ideally on red-hot steel with blue light, point clouds are initially created, which are then combined and visualized to form an overall image using 3D software.
