Work roll change cylinders

Work roll change cylinders are used to extract old roll sets from the mill stand and to insert new roll sets. Roll change out depends on roll wear scale, the number of slabs that it has produced or if the steel grade being rolled is changed. Even though the cylinder is not directly used in the mill process its continuous availability and reliability are very important to guarantee shortest roll change out times.

  • Customized, robust and reliable cylinder design
  • If applicable, a pre-bent cylinder rod to compensate gravity induced deflection
  • Hunger DFE-low friction seals and bearing elements
Technical data:
