Cutting electrode for heating up through the influence of oxygen consists of material forming an electrically conductive oxide layer with a passive rendering effect when heated up on its surface

摘要

An electrode (10) has a first electrode element (EE) (1) embedded in a sheet metal mount (SMM) (3) with the aid of an insulating ceramic sleeve (2). Linked directly to the SMM, a second wire-shaped EE (4) extends parallel to the first EE. The SMM has holes (5) for fastening on an opening in the shell of an arc furnace.
