A dome for an electric arc furnace comprising a central portion of refractory material and a cooled metallic crown consisting of two toroidal conduits joined by radial tubes in such a manner that it is curved. Its own volume permits variations in gas emissions during steel production to be absorbed. It comprises a manifold which fits into an extraction pipeline, so that most of the gas may be collected so as to avoid pollution. A fluid circulates in the conduits and the tubes to cool the crown.
