New Consteel® EAF at Acciaieria Arvedi
Tenova started up the most productive Electric Arc Furnace in history, a Tenova Consteel® EAF, at Acciaieria Arvedi, Cremona (Italy).
On September 18 this year, Tenova started up a record-breaking melting unit, a new Consteel® EAF, at Acciaieria Arvedi replacing the existing Consteel® furnace, originally installed in 2008. The furnace has a tapping size of 300 metric tons and is designed to reach a power-ON time of 37 minutes with a charge mix including up to 30% HBI or other scrap substitutes.
The outstanding productivity performance of the new Consteel® EAF has been designed with the aim to meet the increased demand of the recently revamped continuous casting and rolling mill line of the steel plant. This output has never been achieved before by a single EAF worldwide, and it is made possible thanks to the proprietary Consteel® continuous charging and melting technology of Tenova, complemented by Consteerrer®, an innovative system including ArcSave® electromagnetic stirring, jointly developed with ABB.
“Thanks to the cooperation between the Tenova project team and the plant personnel of Acciaieria Arvedi, we were able to witness a seamless startup of such an impressive machine”, said Silvio Reali, Tenova Senior Vice President. “We are currently proceeding, also on the basis of the recent reconstruction of the cooling towers with a very quick ramp-up phase. After just a few days from the start-up, the furnace is already operating on three shifts.”
The furnace has a 9,1m diameter shell and is continuously fed by a 4m wide Consteel® slip-stick conveyor. The furnace is also equipped with a state-of-the art level 1 and level 2 automation package.
