Abstract
An electrode carrier arm for an electric arc furnace consists of an arm part (10) and of a electrode-clamping device and is produced so as to be current carrying from a material of high conductivity. Between the arm part and the electrode-clamping device there is a flanged connection consisting of flanged plates (11, 12) which limit a cooling-liquid cavity (20, 29) on both sides and which themselves contain passage orifices (21) for the cooling liquid from one cooling-liquid cavity to the other. This allows an effective cooling of the flanged plates and consequently a direct supply of current via the flanged connection when the carrier arm is produced from light metal.
