Abstract

A method for the determination of the wall thickness or of the wear and tear of the lining of a metallurgical fusion pot with a scanner system for contactless detection of the lining area with determination of the position and orientation of the scanner system and allocation to the position of the fusion pot by the detection of spatial reference points, characterized by the following procedural steps: 1. Definition of a space coordinate system as a reference system (e.g. perpendicular euclidean three-dimensional coordinate system) by means of at least two measuring fixed points 2. Definition of at least two spatial reference points in the reference system and measuring of these reference points with known geodetic methods 3. Measurement of the coordinates of at least two points of the horizontal or rotational axis of the involved metallurgical container in the reference system with known geodetic methods 4. Definition of a grid system on the developed view of the theoretical interior of the container lining 5. Scanning of the spatial reference points with a three-dimensional scanner (radiation emitting and receiving measuring instrument). 6. Determination of the scanner position in the reference system 7. prior, simultaneous or subsequent scanning of the inner wall of the metallurgical container in the same scanner position as in the case of scanning of the spatial reference points 8. Detection of the pivoting angle of the fusion pot 9. Calculation of the coordinates of each scan point of the interior of the lining in the reference system and allocation of the scan point to a grid element in the grid system defined in Step 4 10. Determination per grid element of a wall thickness or of the wear and tear of the lining using the coordinates of the allocated scan points and coordinates of randomly selectable reference data 11. Representation of the determined wall thickness or of the wear and tear in the grid system
