Abstract:
The use of AMI SmartFurnace optimization modules in Electric Arc Furnaces and the developments in the optimization of the Oxygen, Natural Gas and Carbon Injection have been continuously improving the steelmaking process in EAFs around the world. One major milestone has been to close the control loop of chemical energy control with the introduction of a Laser Off Gas Analyzer, measuring the CO, CO2, H2O and Temperature of the off gas. The measurements taken by the instrumentation are used by the SmartFurnace Off Gas and Oxygen Module to calculate the optimal setpoints of the EAF burners and lances. The chemical energy modules are complemented dynamic process models and algorithms for electrical energy providing an integral furnace control. The latest implementations of this technology in plants with a wide range of raw materials, EAF mechanical characteristics and production needs are described in this paper, and the achieved results are shown.

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.

Pittsburgh, PA

Tony Klippel, and Prasann Jinturkar from Gerdau – Jackson, TN, along with Jamie Hansen, AMI Automation, will jointly present a technical paper May 07 11:00 am at AISTech 2019 Pittsburgh Room 406. Title: The IoTrode™: A complete system to monitor and optimize all aspects of graphite electrode usage in an EAF Meltshop. The presentation will discuss the installation and the initial results.

AMI Automation has created a new module to add to its successful SmartFurnace™ System of digital tools for EAF melt shops. The IoTrode™ is part of AMI Automations’ furnace optimization system for monitoring, controlling and reducing the consumption of graphite electrodes in EAF (electric arc furnace) melt shops. The IoTrode™ provides for digitization of graphite electrodes for the modern EAF Steel Producer.

Fernando Martinez – Vice President AMI Automation said: “The IoTrode™ is the first in a series of new products AMI will be introducing to assist the EAF steel producer in optimizing and controlling their process.”

AMI is a leader in the field of EAF optimization, control and service. The IoTrode™ is the latest addition to the SmartFurnace™ suite that includes the SmartARC™, and DigitARC™ products that control and reduce electrode consumption. The AMI SmartFurnace™ System improves productivity and reduces energy used per ton of steel.
