摘要
The invention relates to a thermal lance (1) having adequate flexibility and concentrated effective heating capacity for the fusion cutting and/or piercing of any type of material, for example, for piercing and opening tapping passages in melting furnaces that use plugs made of clay or mixtures of, inter alia, alumina, silica and carbon. The thermal lance comprises at least four tubular profiles, one disposed externally and three disposed internally, and more than seventeen cavities housed inside said lance, wherein at least two of said four tubular profiles have different cross-sections, wherein each tubular profile is disposed in a contiguous manner in relation to the other tubular profiles, and wherein each tubular profile is selected from tubular profiles having a circular, square, triangular, hexagonal, oval, or multi-point star-shaped cross-section. The invention also relates to the use of the thermal lance for the fusion cutting and/or piercing of any type of material.
