Deutsche Edelstahlwerke (DEW) operates the world’s first 3-roll block with hydraulic roll adjustment under load from SMS Meer, Germany. The so-called PSM® (Precision Sizing Mill) system replaced two 3-roll blocks at the Siegen-Geisweid site. MEERgauge® enables fully automatic operation of the 3-roll PSM®, independently of the operating personnel.
In the event of dimensional and temperature fluctuations in the starting product, the new MEERgauge® system reduces potential tolerance deviations in the finished product automatically during the rolling process. The technology comprises a precision laser measuring unit for measurement of the cross-section and a highly dynamic monitor control system.
“The control system operates reliably and has surpassed our expectations. The whole process from project planning through to the successful implementation went very smoothly,” says Dr. Thomas Helsper, DEW Rolling Mill Director at the Siegen-Geisweid site.
