Asymmetry of the Short Network during the Operation of Electric Arc Furnaces

A domestic 100-t electric arc furnace (EAF) is used as an example to study the boundaries of asymmetry of the inductive reactance of the furnace circuit that can occur during operation, specifically, during untimely electrode slipping. The designs of current conductors in coplanar and triangulated configurations with current-conducting arms and tube buses along the arms of electrode holders are considered. Triangulation is shown to decrease both the design and operational asymmetry of the short network in any design of the rigid moving part of the current conductor.
