Title: Spot scarfing nozzle for use in gang arrangement
IPC: F23D14/56
Filed: 1977-01-13
Abstract: A scarfing nozzle for producing a fin-free scarfing cut at least as wide as the width of the nozzle. The nozzle comprises an oxygen gas passage terminating in a nozzle discharge orifice characterized by having a central section and at least one end section. The central section is defined by parallel upper and lower edges and is adapted to discharge a sheet-like stream of cutting oxygen of uniform intensity across the metal body to be scarfed. The end section is defined by having at least one of its edges inclined such that the height of the end section is gradually reduced to a lesser value towards the side edge of the orifice but remaining greater than zero at the edge so as to diminish the intensity of the oxygen stream towards the edge of the orifice to the point where the flow of oxygen discharged at the edge is insufficient to scarf the workpiece but sufficient to produce a fin-free scarfing cut at least as wide as the width of said nozzle. This structure allows a plurality of nozzles to operate side-by-side to produce fin-free cuts of preselected width.
