In March 2020, the Gerdau combined bar and wire rod mill, located in Charqueadas Brazil, was successfully commissioned after the revamp. The switchover to the new automation system and drives occurred in just 11 days during a programmed shutdown.
All the equipment from the rougher trio, common mill, wire rod, bar mill and garret coiler outlets were all included within the automation scope of supply. The DC drives for four shears, pinch roll and coilders were upgraded to ABB DCS880. All the main legacy PLC processors, including both Siemens S5 and ABB AC800M and the local IO racks, were replaced with new Siemens S7-1500 PLCs and ET200MP IO boards.
In November 2019, the Gerdau Charqueadas team visited the Russula workshop in Bergondo, Spain. Alexandre Schultz, the Managing Director of Russula in South America, and Jacobo Barragán, Project Manager, accompanied the Gerdau team during the factory acceptance test.
Although the plant shutdown in March, 2020 was partly induced by the coronavirus panademic and subsequent reduced steel demand from the automotive sector, the Gerdau and Russula team took advantage of the available downtime and successfully upgraded the automation and drives of the combined special steel mill.
