SUMMARY:EAF restart at ArcelorMittal Sul-fulminense: Problems and solutions to reach process perfomance goals
DESCRIPTION:After about two and a half years of interruption in production, encouraged by the growing global demand for steel consumption and the prospects for economic growth, the ArcelorMittal Group decided to resume operations at the AMSF Barra Mansa steel mill. The AMSF Barra Mansa plant is equipped with two Electric Arc Furnaces (EAF), each with a capacity to produce 50 tons of steel per heat and a Continuous Casting Machine (CCM). However, the ArcelorMittal Group's planning was to carry out the resumption of the plant operations gradually and according to market movements, so, at first, the plan was to restart only one of these two furnaces, the EAF #2. The first month operation showed that several KPIs were out of goals combined, like power on, tap to tap, electric energy consumption, oxygen consumption and others. This paper aims to present the teamwork carried out between Lumar Metals and ArcelorMittal after the commissioning of EAF #2, implementing the reengineering of the chemical package equipment and adjustments of the electrical and chemical program until the achievement of the results committed to the board of the ArcelorMittal.
