Třinecké železárny awards final acceptance certificate to SMS group for new blooming mill stand

Following the commissioning of its new blooming mill stand, the Czech steel company Třinecké železárny has awarded the final acceptance certificate (FAC) to SMS group.

The objectives of the upgrade were to maintain and ensure the operational reliability and plant availability, to create the necessary process stability and to improve quality, tolerances and yield. Due to the advanced age of the plant this upgrade was an essential investment into the future of Třinecké železárny.

The scope of the upgrade included a new ultra-rigid two-high reversing blooming mill stand with shifting unit and hook-type tilter. The blooming mill is used for the preshaping of intermediates – also of high-alloy steels – made from continuously cast material up to 525 millimeters in diameter and ingots up to a weight of 5.3 tons. Moreover, it is also providing the feedstock material for the existing rail, bar and wire rod production at Třinecké železárny, which shows the importance of this critical modernization project. Another core element of this order is the new hydraulic bloom shear with a shear force of around 1,000 tons. The shear is driven by an innovative and energy-efficient variable-speed pump (VSP).
