Cold rolling mills
Precise knowledge of rolling mill technology facilitates the use of sophisticated technologies in hydraulic screw-downs with precise thickness gauge controls in combination with dynamic drive technology in three-phase AC and DC technology. We have developed comprehensive concepts that we use as solutions in the cold rolling industry.
