The company said the upgrade will expand its product portfolio to include high-strength beams according to Grade 80 ASTM A913/A913M and S500ML EN 10025-4. They are obtained by TMCP from low-alloy-grade-chemistry steels with good weldability and toughness at low temperatures. 

TMCP will be performed by selective flange cooling (SFC) only or in combination with quenching and self-tempering (QST) treating the whole beam. The SFC equipment will be installed at the entry and exit sides of the ultra-flexible reversing (UFR) mill through cooling side guides followed by the QST system at the exit side, the company said. 

Danieli said its QST is comprised of cooling banks and manifolds surrounding the beam surfaces. It features automatic positioning of the cooling manifolds according to the beam size. 

The new system for TMCP will be provided by Danieli Automation, which will guarantee automatic process settings and controls. 

Danieli Research Center estimates its upgrades will reduce water consumption by up to 30%. The high-strength beams will offer savings in material weight and fabrication costs for applications such as high-rise buildings, long-span bridges, seismic areas constructions and offshore structures.
