Italian coil producer Arvedi has started up “…the most productive electric arc furnace in history”, says the equipment’s supplier, Tenova.
The new Consteel EAF was started up on 18 September at Acciaieria Arvedi in Cremona, replacing the existing Consteel furnace, originally installed in 2008, Kallanish learns from Tenova.
The furnace has a tapping size of 300 tonnes and is designed to reach a power-on time of 37 minutes with a charge mix including up to 30% hot-briquetted iron or other scrap substitutes, Tenova explains.
The new Consteel EAF has been designed with the aim to meet increased demand from the recently revamped continuous casting and rolling mill line of the steel plant in Cremona.
“We are currently proceeding, also on the basis of the recent reconstruction of the cooling towers, with a very quick ramp-up phase,” says Tenova senior vice president Silvio Reali. “Just a few days after 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. It is also equipped with a level 1 and level 2 automation package, Kallanish notes.
