When smelting zirconium electrocorundum in an ore furnace, the furnace performance is related to the constant component of the phase voltage. The possibility of selecting optimal technological parameters on the basis of the constant phase voltage is considered. © 2013 Allerton Press, Inc. Source

The emf in the electrode-ground circuit is considered during downtime, when the ore-roasting furnace is switched off. The emf is found to be related to temperature equalization between uniform electrode-melt and lining-melt contacts (the Peltier effect); and also to the temperature gradients in the materials (the Thomson effect). The emf may be used to create a fundamentally new method of assessing the temperature at the electrode's working surface and the thermal state of the bath during downtime. © 2013 Allerton Press, Inc.

When an alternating current passes through an ore furnace, the surface where electrochemical reactions occur moves through the electrically conducting layer. These reactions occur over the whole conducting volume. In this period, the voltage drop at the furnace bath remains constant. This behavior may be employed to assess the parameters of the process: the quantity of conducting material in the furnace bath; and the melt composition. © 2013 Allerton Press, Inc. Source

The influence of voltage and current variation on the power distribution in an ore furnace between the arc, the shunting resistance, and the melt is considered, for the example of a phosphorus furnace. © 2011 Allerton Press, Inc. Source

The mechanism of electrolysis in an ore-smelting cell modeling a bath with a conducting solid material in the melt is considered. An analysis suggests that a number of technological parameters of an ore-smelting furnace can be indirectly controlled by a change in the constant component of the phase voltage and the volt-ampere characteristic of the interelectrode gap. © 2011 Pleiades Publishing, Ltd.
