Abstract
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.
Claims11
A water-cooled cover for an electric arc furnace, comprising:
- a. a peripheral tubular member adapted for water flow therethrough;
- b. a plurality of equally spaced cantilevered beam supports fixed to said peripheral member, extending inwardly and inclined upwardly from said peripheral member;
- c. an equal number of water-cooled panels suspended from and between, and insulated from said cantilevered support beams and from each other by high temperature resistant, electrically resistant insulation;
- d. means connected to a water source and to said peripheral ring for introducing and removing cooling water to and from said peripheral ring;
- e. water conduit means connecting said peripheral ring and each of said water-cooled panels;
- f. each of said water-cooled panels being adapted to surround no more than one electrode no more than about 300.degree..
