Abstract

"SISTEMA INDICATIVO DE FIM DE VIDA úTIL DE PEçAS REFRATáRIAS DESTINADAS à INJENçãO DE GASES EM RECIPIENTES CONTENDO METAIS E LIGAS FUNDIDAS". Sistema indicativo de fim de vida útil de peças refratárias, destinadas à injeção de gases em recipientes contendo metais ou ligas fundidas, caracterizado pela introdução nas peças refratárias de um tubo curvo de aço carbono ou inox, com diâmetro de 2 a 8 mm e que, pela fusão em contato com o aço ou ligas fundidas, interrompe o fluxo de gases, indicando o fim de vida útil do sistema."INDICATIVE END OF LIFE SYSTEM FOR REFRACTORY PARTS INTENDED FOR THE INJECTION OF GASES IN CONTAINERS CONTAINING METALS AND CAST ALLOYS". End-of-life indicative system of refractory parts, intended for the injection of gases in containers containing molten metals or alloys, characterized by the introduction into the refractory parts of a curved tube of carbon or stainless steel, with a diameter of 2 to 8 mm and that, by melting in contact with steel or molten alloys, interrupts the flow of gases, indicating the end of the system's useful life.
