Melting of pellets during arc heating with an analysis of the metal loss in the subelectrode space in a steelmaking bath

The problems of increasing the efficiency of electrosmelting of steel using a system of supplying prereduced pellets through tube (hollow) electrodes are considered. The application of the energy-saving conditions based on the new developed technology is shown to intensify the processes of slag formation and metal heating and decarburization. It is experimentally found that the local supply of iron-ore prereduced pellets under electric arcs into a foamed slag favors a substantial decrease in the dust loss and the metal loss upon melting.
