SUMMARY:Operational results of the revamp of the revamp of the chemical energy package in  electric arc furnaces of 110 ton at acindar
DESCRIPTION:ArcelorMittal Acindar has a capacity of 1,500,000 TON and is an integrated steel production plant, consisting of MIDREX Direct Reduction, Electric Arc Furnaces, Ladle Furnaces, Continuous Casting and Rolling Mill Plants. It produces a wide variety of types of steels, low - medium - high carbon, free cutting, construction, aluminum quenched and low alloy. Leading steel company in the long steel market focused on to increase efficiency and cost reduction of the steelmaking process, planned to revamp the chemical energy package changing the equipment of oxygen and carbon injection on the two 110 ton EAF’s with the goal of decrease the consumption of injected carbon, oxygen and better slag foaming. The two EAF using scrap as charge and feeding DRI continuously with three ports of burner/oxygen and carbon injection. This project consisted in replacing the existing three ports of burner/oxygen and carbon injection for a new EAF chemical package, composed by copper blocks, burners and injectors of oxygen and carbon. Searching for the best technology currently available in the market, Acindar chose the chemical package developed by Lumar to EAF, composed by Protect Block, FlexOx and Power Carbon (to the needy carburization points). In this paper will be presenting the chemical package equipment implemented in these EAF’s revamp, as well the installation project, besides the operational results obtained during startup. The main results were the reduction of the consumption of the carbon, oxygen, improvement of the formation of foaming slag and reduction of power consumption of the furnaces.
