An attempt is made to create a model of the smelting zone under the electrodes for FeCr , and similar, furnaces without recourse to an arc . The conductive medium is described as a slurry: a mixture of liquid slag, ore and carbon particles, drops of liquid metal and bubbles of CO. Current passes from the ellipsoidal-shaped electrode tips, through the conductive slurry, to a liquid metal bath. Divergence of the current generates Lorentz electromagnetic forces which stir the slurry in poloidal loops, downwards along the electrode axis, augmented by buoyancy forces and CO bubbles.The model is scaled to a current of about 110 kA and a voltage around 90 V per electrode. Maximum slurry velocity of the turbulent flow is estimated to be less than 1 m/s so that a loop is traversed in several seconds. The loop is fed from material descending near the electrode periphery.
