The Valve Effect of an Electric ARC and Problems in Controlling Electric-ARC Furnaces
Metallurgist, 2015The reasons for the existence of constant components of current and voltage in electric-arc furnaces are examined. It is noted that the accuracy with which the constant component of arc voltage is evaluated is strongly affected by the method used to sample the voltage signal.

Valorization of Electrical Arc Furnace Oxidizing Slag
2014Valorization of the electrical arc furnace oxidizing slag by coke was carried out by the reduction of iron oxide in the slag. Since the reduction of iron oxide by solid carbon is an endothermic reaction, supply of heat energy is required. In addition, slag has a low thermal conductivity; traditional fuel injection is not suitable for this reaction ...

Modeling and parameter identification of an electric arc for the arc furnace
2008 IEEE International Conference on Automation and Logistics, 2008Voltage flicker and harmonics are the types of power quality problems that are introduced to the power system as a result of arc furnacepsilas very large power input ratings. In order to propose solutions to minimize the adverse effects, developing an accurate electric arc model has a much needed task.
