ArcelorMittal Belval commissions world’s largest straightener for sheet piles

ArcelorMittal Belval, based in Esch-sur-Alzette, Luxembourg, has started up the CRS Compact Roller Straightener supplied by SMS group. It only took four-and-a-half weeks to dismantle the previous equipment and install the new straightener, including successful commissioning. The straightener can handle the largest sheet piles currently produced in the world, expanding the range of products producible at Esch-sur-Alzette.

SMS group supplied the double supported CRS sheet pile straightener on a turnkey basis. The scope of supply comprised the mechanical equipment, electrics and automation, the media supply systems and all the roller change equipment. The straightener, which features a fully hydraulic adjustment system, is the first of its kind to be used exclusively for sheet piles. It has been specially designed for straightening Z-type and U-type sheet piles as well as flat sheet piles.

Equipped with double supported design instead of the conventional cantilever design, the machine provides for a balanced force distribution, leading to better straightening results especially for extra wide sheet piles. The manipulator can change all nine straightening rollers in less than 40 minutes. To facilitate roller changing, operator side housing can be moved out.   Straighteners of the CRS® design, an SMS group development, have been successfully in operation in numerous rolling mills for sections and semi-finished long products. The machines are today’s state of the art.

The challenging revamping project for ArcelorMittal Belval, imple­mented on a turnkey basis, is yet another proof of the SMS group’s leadership position as a supplier of technology for section mills.
