SUMMARY:Reduction of electrode breakage during operation in a 130 ton EAF from ArcelorMittal resende - case study
DESCRIPTION:The problem of electrode broken becomes frequent during the heats along 2020 during Electric Arc Furnace (EAF) operation, which had a very negative impact on the specific consumption of electrodes (kg/t) of the EAF. Given the strangeness of the events and the high cost of this raw material, a working group was formed to analyze the data and find the cause of the excessive amount of electrode breakage. This working group found a strong relationship between skull formation in some regions of the EAF and the electrode breakage. This paper aims to present the methodology used teamwork carried out between Lumar Metals and ArcelorMittal Resende in the characterization of the problem, planning and execution of actions to avoid the formation of skulls in the EAF and consequently to avoid electrode breakages. The gain was the reductions of 66% in the electrode consumption.
