Modern milling.

ArcelorMittal Bremen, Germany, has contracted SMS group to modernize its hot strip mill with the objective of improving hot strip tolerances.

The upgrade will comprise the installation of a CVCplus work roll shifting system with integrated bending mechanism and of new drive spindles in the first three mill stands of the finishing line, plus the installation of a new PCFC (Profile, Contour and Flatness Control). The modernization will provide ArcelorMittal Bremen with a powerful actuator to influence strip profile and strip flatness.

The facility in Bremen is the third hot strip mill of the ArcelorMittal group to be equipped with the CVCplus system (Continuously Variable Crown) by SMS group within a short period. Axial shifting of the work rolls, that come with the special CVCplus crown, combined with roll bending system and the technological process model PCFC permit the roll gap to be perfectly adjusted to changing process conditions and hence to produce strips with close geometrical tolerances. The drive spindles to be supplied to ArcelorMittal Bremen will be SIEFLEX HT gear-type self-aligning spindles (High Torque) developed by SMS group.
