Abstract

"ELEMENTO DE COBERTURA PARA UMA ESCóRIA DE TOPO, PROCESSO PARA SUA PRODUçãO E UTILIZAçãO DO ELEMENTO DE COBERTURA". A presente invenção refere-se a um elemento de cobertura para uma escória de topo de um banho de fusão de metal em um recipiente metalúrgico, especialmente da indústria de aço, contendo um material que derrete sobre o banho de fusão e executa um trabalho metalúrgico, sendo que o material consiste essencialmente de um granulado tornado poroso, cuja porosidade é feita de tal modo que na temperatura do banho de fusão forma uma camada líquida de massa fundida de escória sobre o banho de fusão, e sobre esta, uma camada de isolamento térmico do granulado. A presente invenção refere-se ainda a um processo para a produção do elemento de cobertura e a sua utilização.
