Consteel® EAF
With more than 30 years of history, and over 80 installations worldwide, the Consteel® EAF technology is the best alternative to the conventional EAF for the production of any grade of steel.
Overview
Tenova’s Consteel® Electric Arc Furnace (EAF) is the efficient steelmaking process where the raw feed materials are heated and charged continuously into an EAF and melted by immersion in the liquid steel present in the furnace, while simultaneously controlling gaseous emissions.
Tenova’s Consteel® EAF produces liquid steel with high productivity, a short and adjustable heat cycle and the lowest power cost compared to any other EAF installation using conventional or other alternative steelmaking technology.
The charge is loaded, from a scrap yard, onto the charge conveyor and pre-heated by process off-gas as it is continuously fed into the EAF, where it is melted by immersion in liquid steel. The EAF operates in constant flat bath conditions, a key advantage over conventional batch processes where scrap is melted by the direct action of the electric arc. The EAF gases are sent to a fume-cleaning plant in conditions suitable for the complete combustion of carbon monoxide and other pollutants without any fuel consumption.
