    摘要: A sidewall for a metallurgical furnace and a metallurgical furnace having the same are described herein. In one example, a sidewall of a metallurgical furnace is provided that includes an outer wall, a hot plate and a buckstay. The hot plate is coupled in a spaced apart relation to the outer wall. The buckstay is mechanically coupled to the outer wall and the hot plate. The buckstay includes a buckstay web extending from a buckstay flange. The buckstay web includes a first end coupled to the buckstay flange, and a second end mechanically and movably coupled to the hot plate.

    摘要: 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.

    摘要: An apparatus is disclosed for a metallurgical furnace having a roof with an integrated off-gas hood. The roof has a hollow metal roof section. The hollow metal roof section has a top and a bottom surface. The hollow metal roof section has a center opening configured for one or more electrodes to pass therethrough. An enclosed space is disposed between the top and the bottom surface. A spray-cooled system is disposed in the enclosed space and configured to spray-coolant on the bottom surface of the roof. The integrated off-gas hood has an inlet open to the center opening. The spray-cooled system is also configured to cool the integrated off-gas hood.

    摘要: 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.
