A method for venting a spray-cooled roof of a ladle metallurgical furnace is provided herein. The method begins by processing molten metal materials in a ladle metallurgical furnace having a spray-cooled roof with an opening configured for one or more electrodes to pass there through and an integrated hood. Process gases and fumes are extracted through a channel having walls disposed within an enclosed space of the spray-cooled roof. The walls of the channel are cooled with a spray-cool system extends between the walls of the channel and a top of the spray-cooled roof.

Metallurgical furnace having an integrated off-gas hood

An apparatus is disclosed for a split spray-cooled roof for a tilting metallurgical furnace. The split spray-cooled roof has a center, a first hollow metal roof section and a second hollow metal roof section. The first and second hollow roof sections are attached together along a prescription split line. The prescription split line having a first split line and a second split line, wherein the first split line is not aligned with the second split line and wherein the first and second split line are not aligned with the center.

Split roof for a metallurgical furnace

One embodiment is a cooling system for regulating temperature of a surface of a metallurgical furnace. The cooling system includes a plurality of spray conduits. Each spray conduit has one or more control valves and has a plurality of nozzles. A plurality of temperature sensors are disposed proximate the surface of the metallurgical furnace. A control system adjusts the control valves of the plurality of spray conduits in response to temperature information derived from the plurality of temperature sensors.

An apparatus is disclosed for a metallurgical furnace having a roof with an integrated off-gas hood. The roof has a hollow metal roof. The hollow metal roof has a top, a bottom, an outer sidewall and an inner sidewall. An opening extends from the top to the bottom and is defined by the inner sidewall. The opening is configured for one or more electrodes to pass therethrough. An enclosed space is defined between the top, the bottom, the inner sidewall and the outer sidewall. A spray-cooled system is disposed in the enclosed space and configured to spray coolant in the enclosed space on the bottom surface of the hollow metal roof. A channel having walls is disposed through the enclosed space, wherein the spray-cooled system extends between the top of the hollow metal roof and the wall of the channel.

An apparatus is disclosed for a spray-cooled roof of a tilting metallurgical furnace having a drain pump. The spray-cooled roof has a hollow metal roof section. The hollow metal roof section has an outer metal covering member, an inner metal base member spaced from and opposite the outer metal covering member, an enclosed space disposed between the outer metal covering member and the inner metal base member, and a spray-cooled system disposed in the enclosed space. An evacuation drain is fluidly coupled to the enclosed space and a pump is integrated into the spray-cooled roof and coupled to the evacuation drain.
