Abstract
An improved nozzle 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 includes an exterior wall defining the nozzle face having an arc dimensioned and configured to center the cutting aperture over the desired cut when the cutting torch is clamped to the workpiece. The nozzle also includes a groove for directing the flow of reaction products, thereby minimizing backpressure in the nozzle region, and eliminating the need for a standoff distance.
Claims12
A nozzle for a cutting torch, said nozzle comprising:
- an elongated aperture;
- a bottom face dimensioned and configured to orient said aperture substantially perpendicular to a workpiece;
- a groove within said bottom face, said groove being dimensioned and configured to direct flame and reaction products out of the nozzle substantially parallel to said elongated aperture, whereby back pressure within the nozzle is resisted;
- and
- said nozzle is fabricated from a material selected from the group consisting of mineral/phenolic and high temperature plastic.
A cutting torch, comprising:
- a housing;
- a charge tube dimensioned and configured to slidably fit within said housing, the charge tube containing a powder charge;
- a nozzle dimensioned and configured be retained at one end of said charge tube, said nozzle comprising:
- an elongated aperture;
- a bottom face dimensioned and configured to orient said aperture substantially perpendicular to a workpiece;
- and
- a groove within said bottom face, said groove being dimensioned and configured to direct flame and reaction products out of the nozzle substantially parallel to said elongated aperture;
- whereby back pressure within the nozzle is resisted.
