Abstract

"MéTODO E APARELHO PARA ANALISAR OPTICAMENTE UM BANHO DE METAL EM FUSãO". Um sistema para analisar opticamente um banho de metal em fusão (4) no qual uma corrente gasosa de velocidade alta (3) é passada de uma lança (1) para o banho (4) e é mantida coerente por um envelope de chama (2) para proporcionar um percurso de visualização transparente através da corrente gasosa (3) para visualizar um banho de metal em fusão longitudinalmente através da corrente gasosa a partir de um ponto de visualização espaçado ou remoto (9)."METHOD AND APPARATUS FOR OPTICALLY ANALYZING A MELING METAL BATH". A system for optically analyzing a molten metal bath (4) in which a high velocity gas stream (3) is passed from a lance (1) to the bath (4) and is kept coherent by a flame envelope (2) ) to provide a transparent viewing path through the gas stream (3) for visualizing a molten metal bath longitudinally through the gas stream from a spaced or remote viewing point (9).
