Measurement of geometrical parameters of railway rails in Huta Krolewska steelworks Ltd

摘要

The rail measurement system installed at the Heavy Rolling Mill in Huta Krolewska in Chorzow is a fully automated on-line system used for rail measuring, assessment and qualification. It is also used for manufacturing the sections for turnouts. The system had been designed for measuring the geometric parameters of the transverse sections of rails, straightness and waviness of their running surface and ends straightness in two planes. The measurements are carried out with a set of the laser triangulation probes and laser micrometers with the accuracy of 0.05 mm. The measurement and quality assessment results are displayed on the operators computer screen and stored in the database, with the possibility of generating the detailed reports for each and every rail and/or summary ones according to criteria specified by the system operator.
