Start-up of Tenova Consteel® EAF at Arvedi Plant

19 October 2020

Tenova started up the most productive Electric Arc Furnace in history, a Tenova Consteel® EAF, at Acciaieria Arvedi, Cremona (Italy). 

This record-breaking melting unit replaces 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 electro-magnetic stirring system, jointly developed with ABB.

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.
