ArcelorMittal Downstream Solutions Poland (AMDS) has incorporated new stretch-levelling equipment in its existing cut-to-length line in its Kraków Steel Service Centre which can provide customers with perfectly flat sheets of Amstrong®. These advanced high strength steels (AHSS) have a range of applications in products used in the manufacture of yellow and green goods, railway equipment, and machinery.

The investment at AMDS Kraków will provide customers with ‘laser premium’ material

The investment introduces automated control and measurement of the flatness, internal stresses, and geometry of the strip, during the rolling and cut-to-length processes. For customers, this makes trouble-free processing a reality during their automated laser and plasma cutting operations. The investment in the stretch levelling line was made possible due to a grant from the EU.

The new line includes tools to measure sheet geometry and the internal stress in the steel

The investment at AMDS Kraków will provide best-in-class flatness for customers who rely on fully automatic laser-production lines to process sheets in Amstrong® grades.


Automated laser cutting possible

“Our existing line meets the needs of around 98-percent of our customers in terms of flatness,” notes Rafal Nawrat, CEO of ArcelorMittal’s Steel Service Centres in Poland. “But this is not flat enough for automated laser and plasma cutting lines. These customers require a guarantee that the sheets have a maximum deviation of just three millimetres per metre of material.”

The technology measures the waviness of the steel as it enters the stretch levelling line. “Depending on the result of that measurement, the line will choose whether the coil will be rolled using a standard roll leveller, or the stretch leveller,” explains Kamil Pyzynski, Engineer at AMDS Poland.

Amstrong® properties unaffected

The mechanical properties of the Amstrong® steel are not affected explains Urszula Dzierzon, Head of Distribution for AMDS Poland: “Like all Amstrong® grades, the material maintains good formability and excellent weldability, even after stretch levelling.”
