Abstract:
The optimization task in the Electric Arc Furnace requires a very precise balance of the interaction between the chemical and electrical energy. With the increasing number of high productive EAF, the use of burners, coal injectors and oxygen injection in coordination with electric power play a significant role in improving the efficiency of the steel making process. Besides, with constant changes in demand, produced steel grade, and raw material quality among other constraints, the need for a system capable of adapting to the current operation conditions becomes critical.
With this situation in mind, Duferdofin Nucor, a steel plant located in San Zeno, Italy, made an installation of the AMI technology in their Electric Arc Furnace during the summer of 2018. This paper describes how the AMI SmartFurnace system, featuring the DigitARC PX3 Electrode Regulator together with Electrical and Chemical Energy Input Modules, helped optimize the operation in Duferdofin Nucor, with results in efficiency and productivity. The details of this system are discussed and results of its functionalities are shown.
