A cooling system for the distribution and collection of a fluid coolant in a metallurgical vessel used in the processing of molten materials. The cooling system comprises a distribution system including an intake manifold, a plurality of headers attached to the intake manifold, and a plurality of distribution dispensers positioned along each header. A collection system, including a collection manifold, is positioned to collect the fluid coolant. The distribution dispensers are positioned to direct the fluid coolant towards the collection manifold and utilize the majority of the kinetic energy contained within the coolant to direct the coolant towards the collection manifold.

Furnace cooling system and method

A slag retainer for protecting a water-cooled furnace element through the use of an elongate metal member which extends from inside the furnace, through the furnace wall and into the cooling water of the furnace element so that the insert can be continuously cooled and collected and retain a protective mass of slag.

Device for improved slag retention in water cooled furnace elements

Spray cooled side wall and tap hole cover for an eccentric bottom tap (EBT) electric furnace which is unitary, i.e. one-piece, and has an inter-connected coolant supply and inter-connected spent coolant drain.

Integral side wall and tap hole cover for an eccentric bottom tap (EBT) electric furnace

Jet nozzle for providing a solid cone jet having a housing with a cylindrical bore with different sized removeable caps at each end, one cap having an outwardly flaring nozzle portion and the other cap having an inner surface with discrete raised portions. A washer with an integral key is provided to engage a notch as the fluid inlet means for the nozzle to lock the nozzle in a pre-determined orientation.

Nozzle for spraying liquids

Spray cooled roof assembly for a metallurgical vessel, e.g. an electric arc furnace, comprising two spray cooled components, one of which covers a major portion of the furnace, and the other component of the roof assembly having an integral spray cooled extension for the removal of heated gases from the furnace.

Integral spray cooled furnace roof and fume elbow

Spray cooled roof for a metallurgical furnace in the form of an assembly of separate hollow metal sections, each of which has a separate spray cooling system.

Panelized spray-cooled furnace roof

Two component spray cooled roof for electric furnaces to accommodate off-center electrode positions.

Cooling system for a two component furnace roof

Spray cooled side-wall assembly for an electric arc furnace which includes individual spray cooled segments joined together to form a furnace side-wall. One or more of the segments can be arch-shaped and surround a spray cooled sub-assembly to address conditions of high thermal stress.

Modular spray cooled side-wall for electric arc furnaces

A combination of a spray cooled roof having a central opening, a support member and mast post wherein the roof is provided with an engagement which are detachably engaged to the corresponding engagement affixed to a support arm assembly which extends over a closed part of the roof. The support member is coupled to the mast post which raises, lowers and laterally moves the roof.

Device for lifting and moving the roof of a spray cooled furnace

Hood assembly for pneumatic process metallurgical vessel, such as BOF, which includes removeable spray cooled sub-assemblies at predetermined locations in the hood assembly.

Spray cooled hood system for handling hot gases from a metallurgical

A preformed assembly is provided for the replacement of a thermally stressed portion of a unitary water cooled closure element, e.g. made of plain carbon steel, of a furnace system which includes a steel frame to which is pre-welded a copper covering plate, the steel frame being welded into a closely fitting cut-out in the closure element, e.g. a furnace roof or furnace shell.

Device for relief of thermal stress in spray cooled furnace elements

A cover for a vessel handling heated substances, such as a furnace, in which the cover comprises an outer segment defining an opening in which a removable inner cover segment (delta) is seated and wherein said inner cover segment comprises spaced apart walls defining an enclosed space that contains coolant spray means adapted for spraying coolant onto the wall that is closest to the interior of the vessel.
