CELSA Nervacero puts into operation four laser speed meters
Last month, Celsa Nervacero, together with Russula, has put into operation four laser speed meters in the two-strand rolling mill, located in Bilbao, Spain. The material speed measurement system was installed before the dividing shears for both strands.
The laser speed meters were successfully installed and started-up during a 10-day maintenance shutdown in April 2021. Russula technology experts were on-site to support the commissioning, calibration, and testing.
The initial results while rolling large diameter bars (larger than 20mm) were very good. We noticed improvements right away.
Russula supplied four non-contact laser speed sensors that communicate through profinet, software engineering and commissioning support. Recording the exact velocity is essential for rolling mill optimization. Russula’s speed measurement system consists of a robust, non-contact laser surface velocimeter, suited for steel mill environments. With reliable measurements, the Celsa Nervacero and Russula team were able to optimize shear cutting for large diameter products.
When the bars left the last stand, the speed increased slightly and thanks to the new speed meters, the control system was able to compensate for the changes and the dividing shear made perfect cuts.
