The heat exchange between a metallic melt and a slag with a charge is simulated with allowance for possible formation of a skull on the charge surface. It is shown that the charge melting rate in the melt is determined by the coefficient of heat transfer between the metal and the charge and the ratio of the mass of a charge fragment to its surface area interacting with the melt. A skull is found to form on the charge surface at a low coefficient of heat transfer between the metal and the charge. The main heat parameters, the control of which by an automatic control system ensures an increase in the charge melting rate in the melt and a decrease in the metal loss, are formulated. © 2015, Pleiades Publishing, Ltd.

The heat-and-mass transfer in the working space of an electric arc furnace (EAF) is analyzed on the basis of the real metal losses in industrial furnaces. The energy exchange between the arc discharge and the environmental space of the surface filled with the radiating and absorbing vapor-dust-gas medium is shown to change. The processes of metal evaporation and vapor condensation in the working space of EAF are considered. © 2014, Pleiades Publishing, Ltd. Source

A new treatment system for the exhaust emissions from arc furnaces is described. This system ensures complete combustion of CO and H2, condensation of the steam, coagulation and spheroidization of the dust and slag particles, their cooling to sintering temperatures, and the utilization of 95% of the solid particles in the deposition chamber. That significantly reduces the erosional wear of the gas lines, extends their working life, and reduces water consumption. © 2012 Allerton Press, Inc. Source
