Abstract
"DESCARGA REFRATáRIA AO FOGO". A invenção refere-se a uma descarga refratária ao fogo para integração dentro ou junto da parede de um recipiente metalúrgico, especialmente para fusões de metal, como uma abertura de fluxo de passagem e um tubo de fluxo de passagem que envolve a referida abertura de fluxo de passagem, apresentando o tubo de fluxo de passagem uma superfície que limita a abertura de fluxo de passagem, bem como um alojamento externo. Para aprimorar as soluções conhecidas do estado da técnica, a descarga é caracterizada pelo fato de que o tubo de fluxo de passagem apresenta na seção superior e na seção inferior, a superfície da seção inferior que limita a abertura de fluxo de passagem é formado de um material diferente do que a superfície da seção inferior que limita a abertura do fluxo de passagem, sendo que a seção inferior está presa dentro ou junto da seção superior, ou seja, sendo caracterizado pelo fato de que o tubo de fluxo de passagem possui uma seção superior e uma seção inferior, estando a seção inferior presa junto ou dentro da seção superior e o diâmetro da abertura de fluxo de passagem na seção superior é maior do que na seção inferior.
