Abstract: A report message may be transmitted with collaborated information related to the occurrence of an emergency event. A plurality of devices, such as mobile communications devices, that are out of range of a communications network can communicate via direct communication, such as device-to-device communication, to corroborate characteristics that are indicative of an occurrence of an emergency event. Information related to the occurrence may be collaborated amongst the plurality of devices. A transmitting device, which may be one of the plurality of devices that corroborates characteristics or collaborates information, may generate and transmit the report message comprising the collaborated information. A receiving device may provide the message over a communications network, or the report message may continue to be handed off between devices capable of direct communication, the message eventually reaching a device that is within range of the communications network.

Abstract: An improved vortex inhibitor for separating slag from molten metal during the discharge of molten metal through a nozzle includes a uniform castable refractory body with a generally tapering shape, a hollow chamber within the body and an elongated sacrificial member. The hollow chamber receives the sacrificial member or a mount for the sacrificial member. The refractory body and the sacrificial member combination in molten metal has a specific gravity less than the specific gravity of molten metal and is positioned narrow end downward when supported in molten metal. The hollow chamber can fill with molten metal to form a core that aids in orienting the body in a narrow end downward position. The sacrificial member align the with the area in which the vortex forms and minimizes interference with the flow through the discharge nozzle. The body preferably includes swirl obstructing surfaces.

Abstract: A method and an apparatus for enhanced metallurgical processing of molten metal includes an enclosable ladle chamber (23) for reducing the escape of heat during transport of the ladle from a manufacturing vessel such as a furnace (13) to an intermediate processing (15) or refining station or during processing or transport to a receptacle vessel such as a tundish (17). The method comprises introducing a refractory body into the ladle chamber (23), the body having an adjusted specific gravity having a reduced steel ballast to refractory material ratio that is less than required for a specific gravity required to buoyantly support the body in the molten metal. Preferably, the ratio provides a specific gravity greater than the specific gravity required to buoyantly support the body entirely in the slag layer.

Abstract: A method and apparatus are provided for rapidly and accurately processing the chemical composition of a molten metal bath within a furnace. The apparatus includes a robotically-controlled probe which operates to obtain a sample from any predetermined depth of the vessel. The probe is moved from the vessel to a thermostabilized atomic emission spectrometer in nearby proximity to the vessel wherein a part of the probe containing the sample is joined with an upper chamber housing to form an excitation chamber. Within the excitation chamber, the optical emission spectrum of the sample is excited by an excitation source. The optical spectrum is transmitted to an analyzer where the elemental concentration of the sample is determined. Immediately responsive to this analysis, adjustments are made in processing to achieve the target grade of steel.
