Sep. 13, 2019 - Following last year’s order for a new 18-stand rolling mill, Nucor Steel has chosen Danieli to supply a new Quenching and Self-Tempering system, to be installed at the same mill in Marion, Ohio.
The Quenching and Self-Tempering process improves the mechanical properties of deformed bars, in particular the yield strength, using billets with lower alloy content. The result is a product with final technological characteristics equal to or even better than those obtained by low-alloyed/micro-alloyed steels. The new system is designed for rolling speeds up to 13 m/s for single and multi-strand rebar, and it is controlled by a dedicated stand-alone system provided by Danieli Automation.
