Vortexer apparatus

ActiveUS20060180963A1Facilitates submergence and meltingMaintain temperatureStirring devicesCharge manipulationImpellerPositive pressure
The present invention features a vortexer apparatus including a vessel comprising an exterior surface, an interior surface containing fluid and a mouth for receiving material at an upper end portion of the interior surface. In one application the material is metal scrap that is melted in molten metal as the fluid. All components that contact the molten metal are formed of refractory material. An outlet passageway extends downwardly from the interior surface. A vessel inlet opening is located between the exterior and interior surfaces above the outlet passageway. A center line passes through a center of the interior surface and the vessel inlet opening is disposed at a location offset from the center line. A pump is adapted to pump fluid into the vessel effective to form a vortex of fluid in the vessel. The base and impeller are configured and arranged effective to provide molten metal leaving the base outlet with a positive pressure. An outlet conduit extends from the base outlet to near the vessel inlet opening and can be maintained at a temperature above which molten metal solidifies, along its entire length. Instead of the vortexer vessel, the inventive vortexer apparatus may integrate a chamber of a furnace (e.g., a charge well). The chamber may be rectangularor include arcuate portions. Corner inserts may be used to provide the chamber with an oval or generally circular shape that may facilitate the vortex. One feature of the invention is a vortex vessel that includes an offset inlet opening and lower circulation opening. Also featured is a baffle impeller that may be vaned or barrel type. In addition, the invention features a pump having upper and lower impeller chambers separated by a web in the base, and impeller outlets that are isolated from fluid communication with each other.

Multi-purpose, multi-oxy-fuel, power burner/injector/oxygen lance device

A multi-purpose, multi-oxy-fuel High Temperature Power Burner/Injector/Oxygen Lance, Mechanical System Apparatus Device, for steelmaking from recycled scrap and/or virgin ferrous charge, which can be employed in multi-oxy-fuel (natural gas; pulverized carbonaceous matter; heavy oil), especially by Oxygen Combusted mixture of Natural Gas/Pulverized Carbonaceous Matter in High Temperature Power Burner Mode, for efficient and rapid melting of solid ferrous charge (cold or preheated) in a special steelmaking Metallurgical Furnace or Open Hearth Furnace, Tandem Furnace, BOF, EAF, as its augmenting or only source of thermal energy; more than one Device in Oxygen-Natural Gas/Pulverized Carbonaceous Matter Power Burner Mode, can be employed as the only source of thermal energy in a modified, originally Electric Arc Furnace, as total replacement of Graphite Electrodes and Electric Arc System, the replacement being noticeably more primary energy efficient than the thermal energy provided by Graphite Electrode/Arc System; it also can be employed in an Solid Particles Injector Mode, for injecting of adequately granulated carbonaceous materials or lime into the molten steel for its carburizing or for foamy slag control; further it can be employed in a natural gas shrouded, pulsating oxygen stream, for vertically to the charge oriented soft blow supersonic Oxygen Injection Lance Mode, for decarburization of the molten metal contained in the hearth of the metallurgical furnace and foamy slag control; in one of the embodiments-generally arcuate-pivotally mounted, liquid media cooled composite body, is pivoted into and out of a furnace vessel through a small opening in the shell wall for auto-regulated constant optimal positioning of the Composite Body Tip against solid or molten charge, in each and all multi-purpose modes; furthermore, when inserted into the furnace vessel, the arcuate composite body can be rotated about its longitudinal axis for directing the oxy-fuel high temperature flame towards unmolten charge in the furnace; in an other-generally linear-embodiment, the liquid cooled composite body is attached to the mast type carrier allowing vertical movement of the composite body which enters the furnace vessel through a small opening in the furnace roof; the bimetallic, liquid cooled special tip assembly of both-arcuate and linear embodiments-of the composite body includes easy replaceable, independent, multi-opening nozzles, mounted in a protective, retracted position inside of the liquid cooled special tip assembly.
