Abstract

"TAMPãO PARA FURO DE CORRIDA DE UM FORNO DE REFINO DE AçO". Um tampão possui uma barra metálica (1) que passa através de uma cabeça do tampão cerâmico moldado (2) e, em seguida, através de uma haste cerâmica cilíndrica do tampão (3). Uma camisa (4) de um material carbonáceo, ou reativo, fica disposto em torno da haste (3), ou uma camada desse material pode ser formada na face inferior (5) da cabeça do tampão (2) (na interface entre o aço e a escória). Um bloco, ou camisa (6), de um material reativo adequado poderia ficar posicionado na face superior (7) do tampão. O material reativo poderia ser papelão, ou papel, ou um metal reativo, tal como aluminio ou magnésio. De qualquer forma, resultará numa reação química com o aço líquido em um corrente ascendente no aço, o que afasta a escória da área do furo de corrida.
