Technical Data CONSTEEL

Tenova is able to assist its customers in the entire offer and design phase of the plant, providing a service that translates into a tailor made configuration with respect to the specific needs of each case. 


  • AC/ DC type furnace 
  • 25 to 300 tons heat size 
  • 30 to 420 tons per hour productivity 
  • Full platform / half platform design 
  • Many layout variants available, to fit different melt shop reality 


In the Tenova’s Consteel® EAF process, charge materials melt by immersion in a molten pool heated by energy coming from the electric arcs and from the chemical reactions taking place in the liquid phase, not by direct energy transfer from  the arcs or burners, as in the conventional Top-Charge EAF. The preheating of the charge helps reducing the energy requirements of the process. 

  • High flexibility in metallic charge mix (scrap, pig iron, hot metal, HBI/DRI, scrap surrogates, skulls) 
  • Scrap Tracking System for better control the raw material input 
  • High melting efficiency 
  • High productivity even on weak power grids  
  • Higher yield of the metallic charge 
  • Low OPEX 
  • Exceptional reliability: >98% on the whole unit, >99,5% on the conveyor 


Among other references, Tenova is proud to have designed and supplied the most productive electric arc furnace in the World, the Consteel® EAF at Acciaierie Arvedi.
