According to Danieli, the improvements to the No. 2 rolling mill at Gerdau SA’s Pindamonhangaba facility in São Paulo were carried out during scheduled maintenance outages. Work included installation of a new programmable logic controller governing mill speed and a new control desk with key panel. Process controls for the Garrett coiling lines also were improved, Danieli said. 

“Now, the setup of entire rolling mill is managed by a new technological workstation in centralized mode. Moreover, all human-machine interface screens have been redesigned using Danieli Automation standards. To ensure effective traceability of the product, unfinished steel exiting the reheat furnace is followed by a precise tracking system,” the company said. 

Danieli said Gerdau has issued the final acceptance certificates on the upgrades.
