THERMAL LANCE COMPRISING AT LEAST ONE HOLLOW TUBULAR PROFILE MADE OF ALUMINIUM AND/OR MAGNESIUM, AMONG OTHER MATERIALS, WHICH ALLOWS SAME TO BE USED IN PROCESSES REQUIRING A LARGEAMOUNT OF ENERGY TO CUT, PERFORATE, AND/OR MELT MATERIALS HAVING A HIGH THERMAL REQUIREMENT

摘要

The invention relates to a thermal lance (1) consumable by an exothermic reaction used to perforate and/or cut any type of material of different thicknesses and dimensions, the lance comprising a main outer tubular body (2) and at least one hollow inner profile (3) and/or at least one hollow inner profile (4) that is made of aluminium and/or magnesium and/or another material and has a different cross section, the profiles being located concentrically with respect to each other and/or with respect to the main outer tubular body (2), cavities (5) being formed between each hollow inner profile and/or the main outer tubular body, the cavities forming passages (6) for oxidising gas that flows through the length of the thermal lance (1), wherein the cavities must have at least one straight part and at least one curved part to allow the flow of oxidising gas to pass through the lance with a suitable turbulence during the operation thereof.
