Abstract

FUNDOS DE CONCHA DE ELEVADO RENDIMENTO. A presente invenção está relacionada a um fundo de refratário para um recipiente metalúrgico que compreende um revestimento de fundo que possui uma superfície de fundo que é dimensionada para revestir um fundo de um recipiente metalúrgico e uma superfície superior. A superfície superior compreende uma pluralidade de seções discretas que incluem uma seção mais superior, uma seção intermediária e uma seção mais inferior. Cada seção possui uma superfície superior a uma elevação discreta tal que a superfície superior da seção mais superior apresenta uma elevação mais alta e a superfície superior da seção inferior apresenta uma elevação mais baixa. A superfície superior da seção mais superior, a seção intermediária e a seção mais inferior compreendem uma série de seções sucessivas em degraus que definem um percurso em degraus a partir da seção superior de modo decrescente para a seção inferior. Cada seção sucessiva da superfície superior é mais baixa que uma seção precedente.
