Alberto Passon

A Mechanical Engineering graduate from the Udine University with a thesis on Geothermal Power Plants based on ORC Technology. He joined Danieli in 2011 and starting 2018 he has been appointed Danieli Sales Manager for MENA Region. He is speaker at various Danieli events and international technological meetings, including Metal Bulletin MEIS, seminars and conferences focused on Danieli New Vision for Electric and Oxygen Steelmaking.

Topic: Danieli Electric steelmaking: with Q-MELT and Q-ONE the future is now

Abstract: Q-MELT Automatic EAF, thanks to self-learning capabilities, is able to drive the furnace in automatic mode towards the optimal operation conditions, by analyzing all the process variables to reach a given target. The MELT MODEL automatically adapts the process to reach the targets imposed by the specific production grades; it provides automatic correction of the melting profile on the L2; and it allows the consolidation of the plant best practices according to the selected KPI’s. Q-MELT Automatic EAF decreases conversion costs and increases market competitiveness.

Q-ONE is representing a completely new approach in terms of electric energy supply to EAF has immediate benefits like; precise current control on EAF electrodes, wider range of active power, power factor close to one. Electrode consumption, thermal stress on EAF panels, mechanical stress on electrodes and arms are reduced. Tap-to-tap time is shortened and electric energy consumption is decreased. The impact on electric network in terms of flicker, voltage and current unbalances, phase shift is practically negligible, since Q-ONE is decoupling the circuit that is feeding the EAF from the electrical distribution.
