Mathematical Modeling of Postcombustion in an Electric Arc Furnace (EAF) [PDF]
Metals, 2019 Numerical modeling was used to study the capability of postcombustion in an electric arc furnace (EAF) equipped with virtual lance burners. The CO flow rate at the molten bath surface was estimated using the off-gas data obtained close to the outlet of ...

Health status of male steel workers at an electric arc furnace (EAF) in Trentino, Italy. [PDF]
J Occup Med Toxicol, 2016 The aim of this retrospective cohort study was to determine if the workers of an Electric Arc Furnace (EAF), which recycles scrap, had higher mortality and morbidity due to possible exposure to pollutants at work. EAFs do not run on coke ovens. In EAFs 40 % of the particulate matter (PM) is made up of PM 2.5.

Journal of Physics: Conference Series, 2021 Abstract The effect of arc length on heat exchange and specific power consumption in electric arc steel-making furnaces was studied. A modern electric arc steel-making furnace (EAF) with a capacity of 100-tons of metal, EAF-100, was used as the study model. With an increase in the arc length from 300 to 425 mm, that is, by 1.42 times and
