Objetivo

In modern high-powered DC EAF plants operating with large electrodes, discontinuous electrode consumption events such as electrode breakage or tip drops remain a problem and have a clear impact on final steel costs. Mastering this problem implies a better knowledge of the involved phenomena. Therefore, an optical system for electrode monitoring after the melting of each scrap basket will be installed at the single shell DC EAF of ProfilARBED Esch-Belval.

The measurement of the progressive electrode consumption (on tip and side) and the observation of crack formation, joint openings, tip drops and electrode breakages will allow establishing the relationships with electrode grade, nipple type or nipple screwing technique as well as with furnace operating parameters. Using the available data, existing calculation model for electrode consumption will be updated and improved.

Additional pilot tests in a 1t DC EAF will allow focusing enlarged investigations on well-controlled parameters. Guidelines to reduce the electrode consumption will be established. Moreover, the applicability of the electrode monitoring system will also be tested at the twin-shell DC EAF of ProfilARBED Differdange.
