Abstract

Raw material feed into an electric arc furnace (“EAF”) is melted into heated liquid metal at a controlled temperature with impurities and inclusions removed as a separate liquid slag layer. The heated liquid metal is removed from the EAF into a passively heatable ladle wherein it is moved into a refining station where they are placed into a inductively heated refining holding vessel and wherein vacuum oxygen decarburization is applied to remove carbon, hydrogen, oxygen, nitrogen and other undesirable impurities from the liquid metal. The ladle and liquid metal is then transferred to a refining station/gas atomizer having a controlled vacuum and inert atmosphere wherein the liquid metal is poured from an inductively heated atomizing holder vessel into a heated tundish at a controlled rate wherein high pressure inert gas is applied through a nozzle to create a spray of metal droplets forming spherical shapes as the droplets cool.

Abstract

A process and a plant for preheating a metal charge fed in continuous to an electric melting furnace through a preheating tunnel provided with a horizontal conveyor, wherein the metal charge is hit, in countercurrent, by the exhaust fumes or gas leaving the electric melting furnace and by jets of gas ejected through a plurality of nozzles positioned on the hood of the tunnel. The nozzles are arranged in groups interspaced from each other in a longitudinal direction with respect to the tunnel, and generate a small-scale turbulence or inject small fast gas jets that can penetrate the main gas stream passing through the preheating tunnel, and simultaneously generate a “horseshoe vortex” structure composed of a descending central gas flow (“downwash”), and ascending flows (“upwash”) close to the side walls of the preheating tunnel, which enable a desired circulation of the gases.

Abstract

Electrorefining cells and methods for electrorefining ferrous molten metal (e.g. steels), that includes impurities (e.g., carbon), are described. Liquid metal is provided in ladle with a molten electrolyte on top of it to form a metal-electrolyte interface. An electrode connection is put into contact with the metal for electronic conduction therewith, while a counter electrode is put into contact with the electrolyte for forming an electrolyte-counter electrode interface. Both the electrode connection and the counter electrode remain in the solid form in, and inert to, the metal and the electrolyte, respectively. The electrode connection and the counter electrode are made of an electronically conductive material. Therefore, during electrorefining operations, an electromotive force can be supplied between the electrode connection and the counter electrode so as to induce electrochemical reactions to occur at both the metal-electrolyte interface and the electrolyte-counter electrode connection, producing a ferrous molten metal depleted of the impurities.

An optically based combustion off-gas stream velocity sensor assembly is provided for detecting in real-time off-gas flow velocity and/or volume as it moves through a flue duct. The sensor assembly includes two paired coherent light emitters and optic sensors, positioned in a spaced orientation in the flow path direction. The light emitter/optic sensor pairs operate to emit and detect across the off-gas stream coherent light beam energy having a wavelength component corresponding to an absorption profile of an off-gas species component.

Abstract

A process and a plant for preheating a metal charge fed in continuous to an electric melting furnace through a preheating tunnel provided with a horizontal conveyor, wherein the metal charge is hit, in countercurrent, by the exhaust fumes or gas leaving the electric melting furnace and by jets of gas ejected through a plurality of nozzles positioned on the hood of the tunnel. The nozzles are arranged in groups interspaced from each other in a longitudinal direction with respect to the tunnel, and generate a small-scale turbulence or inject small fast gas jets that can penetrate the main gas stream passing through the preheating tunnel, and simultaneously generate a “horseshoe vortex” structure composed of a descending central gas flow (“downwash”), and ascending flows (“upwash”) close to the side walls of the preheating tunnel, which enable a desired circulation of the gases.

Abstract

Pyro-hydrometallurgical methods are described to economically and environmentally recover a target metal from iron slag or steel slag. For instance, the method can enable subjecting an iron or steel slag feed to acid-baking with an acid to produce a dried mixture comprising at least one soluble metal salts, then subjecting the dried mixture to water leaching to an aqueous solution comprising an aqueous leachate rich in said target metal and solid residues and subsequently separating the aqueous leachate rich in said target metal from the solid residues. This acid-baking water-leaching method facilitates efficient recovery of target metal compared to conventional methods.

The invention relates to a cooling device for cooling planar or web-like metal sheet, comprising at least one first transport roller (1a, 1b, 1c, 1d), which has a drivable rotatable support tube (3) that is provided with support elements (4) which form a transport plane (T) for transporting the sheet (2) in the travel direction (D) through the cooling device. According to the invention, the support tube (3) has nozzle openings (8). A non-rotatable channel (5) for a first coolant is formed in the support tube, the channel (5) being connected to a first coolant feed (6). The channel has at least one cut-out (7), through which the first coolant can flow, in order to conduct the first coolant to the nozzle openings (8), by means of which the first coolant can be applied to a first side (2a) of the sheet (2) over the width of the sheet. The invention also relates to a cooling method, comprising the steps of: - feeding a first coolant to a channel (5) which is formed in the support tube (3); - conducting the first coolant through cut-outs (7) in the channel (5) to nozzle openings (8) in the support tube; and - cooling the sheet (2) by applying the first coolant to a first side (2a) of the sheet (1) over the width of the sheet.

Abstract

An optically based combustion off-gas stream velocity sensor assembly is provided for detecting in real-time off-gas flow velocity and/or volume as it moves through a flue duct. The sensor assembly includes two paired coherent light emitters and optic sensors, positioned in a spaced orientation in the flow path direction. The light emitter/optic sensor pairs operate to emit and detect across the off-gas stream coherent light beam energy having a wavelength component corresponding to an absorption profile of an off-gas species component. The detection of non-absorbed portions of the emitted beam is used to identify and detect the movement of a flow species signature at different locations along the flue duct.

Abstract

A system used in monitoring one or more operating parameters of a coolant-fluid cooled industrial installation includes one or more an acoustic sensors positioned to receive and sense one or more acoustic signals in an installation coolant-fluid flow. The acoustic sensor assembly operates to emit and sense acoustic signals at frequency ranges above and/or below the background noise frequency ranges which are associated with the normal industrial installation operation. Output data signals representative of sensed acoustic signals are compared to target frequency profiles predetermined as representing an acoustic frequency associated with a predetermined installation operating parameter or event.
