Title: THERMITE TORCH CUTTING NOZZLE
Abstract:
An improved nozzle (100) for thermite cutting torches provides an elongated nozzle dimensioned and configured to direct a maximized flow of cutting flame to the desired cutting location on a workpiece. The nozzle (100) includes an exterior wall (102) defining the nozzle face having an arc dimensioned and configured to center the cutting aperture (104) over the desired cut when the cutting torch is clamped to the workpiece. The nozzle (100) also includes a groove (112) for directing the flow of reaction products, thereby minimizing backpressure in the nozzle region, and eliminating the need for a standoff distance.
