Abstract: A burner enclosure for use in locating a burner in an a wall of an electric arc furnace, the burner enclosure includes a plurality of walls wherein each wall includes a serpentine cooling path therein and an inlet located proximal a first edge of each wall and an outlet located proximal a second edge of each wall and wherein the walls are assembled into the burner enclosure so an inlet of one wall can be connected by an elbow to an outlet of an adjoining wall to create a cooling fluid flow path through the entire burner enclosure to improve the performance of the burner in the burner enclosure and to improve the overall efficiency of the electric arc furnace.

Abstract: A forged copper burner enclosure capable of being mounted within the side wall of a steel melting furnace for the purpose of providing an improved cooling characteristic to a burner lance. The burner enclosure is provided with a central passage adapted to receive a burner lance for injecting oxygen into the batch of molten metal of an electric arc furnace. The forged burner enclosure is positioned such that only a solid forged copper face is on the furnace side when installed. The burner enclosure has an optional through hole which can be used for the purpose of treating the metal melt with particulate supply ranging from slag forming materials to metallurgical materials.

Abstract: A cooling panel for use in drawing off excess heat from and protecting the side walls and roof of a furnace such as an electric arc furnace, the cooling panel being preferably made entirely out of oxygen-free pure copper. The cooling panel is a wall having a series of strips welded on one side, the strips having recesses on the side adjacent the wall to form channels between the strips and wall for circulating a cooling fluid therethrough. The cooling panel is also provided with inlet and outlet manifolds for supplying and removing the cooling fluid to the passages of the cooling panel. The strips and the manifolds are preferably made using an extruding process and assembled using a tungsten inert gas welding process.

Abstract: Each welding cable terminal component, such as a semi-cylindrical terminal half, near its rearward end is provided with a semi-cylindrical recess in which the cable conductors are received and held in position by a clip in the form of an endless band having a partially cylindrical external portion snugly fitting a corresponding external semi-cylindrical groove in the terminal component. A chordal inner portion of the clip is pressed forcibly into compressing engagement with the ends of the cable conductors within the recess, whereupon molten solder is flowed into the recess under the clip between the hair-like wires of the strands of the cable conductors, thereby forcibly holding the cable conductors firmly in the recess while the solder permeates the entire cable conductor ends within the recess. The terminal components of which there are at least two, are then assembled with an insulating strip between them and clamped together, as by bolts.
