Abstract
An electrode for arc furnaces comprising a top portion of metal and a replaceable bottom portion of a material which, when appropriate, is only slowly consumed having a substantially cylindrical shape and being joined each to the other by a screwmounting, for example by means of a screw nipple or the like. The top portion includes a liquid cooling device or means with a header and a return duct, and an insulating coating of high temperature stability. An inner part and an outer part of the top portion are constructed so as to be detachable each from the other. The inner part extends substantially adjacent the screw nipple and at least a portion of the inner part is provided with an insulating coating of high temperature stability, which represents a loosely surmounted moulding.
