Reduction of Electrode Breakage During Operation in a 130-Ton EAF From ArcelorMittal Resende – Case Study

The problem of broken electrodes became frequent in 2020 due to skull falling during the process of heat. This working group found a strong relationship between skull formation in some regions of the electric arc furnace (EAF) and electrode breakage. This paper aims to present the methodology carried out between Lumar Metals and ArcelorMittal Resende in the characterization of the problem, and planning and execution of actions to avoid the formation of skulls in the EAF and consequently to avoid electrode breakages. The result was a reduction of 66% in the electrode consumption.
