| 摘要 |
A water cooled roof for an electric arc furnace made up of a multiplicity of water cooled panels surrounded by a water distribution and collection ring, each portion of the roof being insulated from each other portion, including the roof panel, support arms and the roof rack. The invention provides a means for interrupting the flow of an inductive current around each electrode by creating a gap in the metal surrounding each electrode, thus insulating the furnace roof or cover from each phase of the three phase current.
