ArcelorMittal Gent, Belgium

New technology for high-strength grades

Determined to expand its high-strength steel grades portfolio, ArcelorMittal Gent awarded SMS group a contract to revamp its hot strip mill.

The project involves installing two new finishing stands (F1 and F2), modifying stands F3 and F4, and replacing all loopers. Applying the new equipment, modern actuators, and higher rolling forces ensures ArcelorMittal Gent can continue expanding its portfolio of third-generation UHSS and AHSS grades and improving product quality.

The first modernization step was realized in December 2015. It entailed revamping the drive trains of finishing stands F1 to F3 with more powerful main and pinion gears as well as Sieflex® HT high-performance spindles.

In November 2016, the new mill stands will be implemented. To make sure the extremely tight downtime schedule can be realized, the equipment has been completely installed in the SMS group workshop and comprehensively tested. The tests included testing of mill stand functions such as adjustment and balancing systems or the entry and exit guides.

Before the start of the revamp at ArcelorMittal Gent, the new mill stands will be assembled next to the mill line. During the shutdown, they will be shifted to their final position by means of a special lifting system.



Scope of modernization

  • F1 + F2: New mill stands with hydraulic adjustment system and CVC® plus
  • F3 + F4: New hydraulic and mechanical adjustment system to increase roll force, new oil film bearings
  • F1 - F3: New mechanical drives including Sieflex®-HT spindles
  • F1 - F6: New loopers
  • New PCFC® (profile, contour, and flatness control) for finishing mill
