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. © 2016, Pleiades Publishing, Ltd.

The influence of the reducing-gas distribution in Midrex furnaces is investigated. The temperature of the tuyere belt in the furnace lining is studied experimentally, and blockage of the tuyeres by buildup is analyzed. The tuyeres are mainly blocked on account of the nonuniform reducing-gas distribution, which is associated with the temperature gradient over the length of the tuyere belt. © 2013 Allerton Press, Inc.

When hot-briquetted iron is used for steelmaking in a 150-t arc steel-melting furnace, the heat time decreases, the barren rock content decreases, and the degree of metallization of HBI increases. © 2010 Pleiades Publishing, Ltd.
