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

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

Cooling system for a two component furnace roof

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

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.

Cooling system for furnace roof having a removable delta

A combination left- and right-handed roof system adapted for use in electric arc or other furnaces having roof removal in either a clockwise or counterclockwise direction. The roof system is spray cooled by a coolant and includes a coolant drain system divided into at least two segments and having opposing inlets for receiving spent coolant. Two pairs of adjacent coolant outlets are provided for connection with a coolant collection pump, depending upon the direction of roof removal, and each outlet in each of the pairs is associated with a different drain system segment. A removable U-shaped conduit connects the two outlets of the pair disconnected from the coolant collection pump. Coolant may flow from one inlet, directly through a single drain system segment, and be removed from the roof through one of the connected outlets. Coolant may independently flow from the opposite inlet, through the U-shaped conduit and another drain segment, and be removed from the roof through the other connected outlet.
