A Mathematical Model Describing Forces and Circulation in an Electric Smelting Furnace

Conditions in the slag bath of an electric smelting furnace are examined as are several existing models for such furnaces. A digital model that provides an improved simulation of the slag bath is described. The model is used to determine the electrical resistance between electrodes and can be used to examine the nature of the electromagnetic forces that exist near the electrode tips. The mechanism by which these forces produce bath circulation is described.
