摘要： Disclosed herein is a metallurgical furnace and roof having a drain system. The roof has a roof body comprising a top surface having a center opening, a bottom surface opposite the top surface, and an outer sidewall connecting the top surface to the bottom surface. The outer sidewall, the bottom surface and the top surface define an interior portion. An internal spray cooling system is disposed in the interior portion of the body. A drain system is integral with the body. The drain system has a roof evacuation conduit disposed outside the interior portion and configured to collect spay coolant from the interior portion of the body. The drain system additionally has a drain box having a vent and an exit pipe, wherein the roof evacuation conduit channels spent coolant by gravity into the drain box which is evacuated under gravity by the exit pipe.

摘要： Embodiments of the present invention relate to automatic sanding hopper systems and methods for supplying sand to a tap hole in a furnace. The automatic sanding hopper system may automatically open a chimney door to provide access to a furnace through a chimney hole. A hopper assembly in the sanding hopper system may automatically move to a position in which a plunger may automatically actuate to clear or clean out the chimney hole. The hopper assembly may thereafter automatically move to a position in which a sand dispenser delivers sand through the chimney hole, into the furnace, and into the tap hole in the furnace. A sensor device may determine whether or not the tap hole is properly filled with sand. The hopper assembly may automatically retract and the chimney door may automatically close to begin another steelmaking heat.

摘要： A method and apparatus for optimizing melting of titanium for processing into ingots or end products. The apparatus provides a main hearth, a plurality of optional refining hearths, and a plurality of casting molds or direct molds whereby direct arc electrodes melt the titanium in the main hearth while plasma torches melt the titanium in the refining chambers and/or adjacent the molds. Each of the direct arc electrodes and plasma torches is extendable and retractable into the melting environment and moveable in a circular pivoting or side to side linear motion.

摘要： A melting or holding furnace includes a furnace chamber surrounded by a housing. The chamber holds the melt with a maximum filling level. The furnace also has an outlet opening for transferring the melt to another container. The outlet opening is provided with a shut-off valve for dosing the emerging melt. The valve is covered by melt in normal operation. The housing is connected to a tilting device which tilts the housing in such a manner that the shut-off valve can be freed from melt for the purpose of repairing it even at a maximum filling level.
