According to Tenova, the furnace is the most productive EAF ever built, with a tapping size of 300 metric tons and a power-on time of 37 minutes. Tenova said the output was made possible by combining its proprietary Consteel® continuous charging and melting technology and an innovative electromagnetic stirring system that was jointly developed with ABB.

The furnace shell is 9.1 m in diameter and is continuously fed by a 4-m Consteel® slip-stick conveyor.  

“We are currently proceeding with a very quick ramp-up phase. After just a few days from the start-up, the furnace is already operating on three shifts achieving high production rate and performances,” said Tenova senior vice president Silvio Reali.
