Abstract (en)
[origin: DE19748310C1] The invention relates to a method and device for controlling the formation of foamed slag in an arc furnace (5) to which the carbon is fed in such a way that the arc is at least partially enveloped in the arc furnace (5) and an over abundant feeding of carbon is avoided. The quantity of the carbon which is fed to the arc furnace is thus determined by means of a foamed slag model (25) according to the quantity of at least one of the coating materials comprised of scrap metal, steel, alloy material or admixtures.
