A method of torch-cutting steel, typically slab steel, produced by continuous casting wherein a cutting torch is fueled with propylene and oxygen and wherein the fuel is mixed and combusted on the surface of the slab thus permitting the cutting of the slab to proceed contemporaneously with the production of slab steel by the continuos casting process.

Um método do aço do tocha-corte, tipicamente aço da laje, produzido pela carcaça contínua wherein uma tocha de corte é abastecida com propylene e oxigênio e wherein o combustível é misturado e combusted na superfície da laje que permite assim o corte da laje proseguir contemporaneously com a produção do aço da laje pelos baixos contínuos que moldam o processo.
