Abstract

"MéTODO PARA MONITORAR O USO E ESTENDER A DURAçãO DE UM REVESTIMENTO REFRATáRIO DE ALTO-FORNO" é proporcionado um método para monitoramento on-line do uso de um revestimento refratário de um alto-forno. O método inclui determinar a linha de uso do revestimento a partir de sinais proporcionados por sondas de temperatura localizadas em grupos, por exemplo, o grupo (10, 12, 14) , o grupo (16, 18, 20) , o grupo (22, 24, 26) , embutidos em localizações espaçadas através da espessura do revestimento refratário. Outros métodos revelados incluem: um método para determinar a espessura de uma camada protetora de crosta grossa de metal solidificado formada no cadinho do refratário, um método para determinar as condições da transferência de calor entre um revestimento refratário e um casco de metal de um alto-forno e entre o casco de metal e a água de esfriamento aplicada ao casco e um método para estender a duração do revestimento refratário.
