20-high mill SplitBlock design

SplitBlock: Upper and lower roll sets and flexibility in between

There are various actuators or control elements for roll-gap setting that ensure the SplitBlock stand can process the whole range of strip qualities. Also featured is a thickness and flatness control system. All rolling parameters are preset by SMS group on the basis of a mathematical model and controlled fully automatically during the rolling process. The mill is manufactured in modular design.

Beside the rolling stand, the main features are:

  • Entry and exit side high-tension reversing coilers
  • Additional uncoiling station with leveler unit
  • Entry and exit side belt wrappers
  • Continuous paper feed
  • Fully automatic roll changing robots
  • Supafine® filtration system for rolling oil
Cold rolling mill SplitBlock
Main actuators of the SplitBlock design are servohydraulic roll-gap control (AGC), crown adjustment for backup shafts A/D and F/G as well as shifting of first intermediate rolls by means of a push/pull system.
