Abstract

PROCESSO DE MEDIÇÃO DO NÍVEL DE SUPERFÍCIE DE METAL LÍQUIDO E DO NÍVEL DE SUPERFÍCIE DE ESCÓRIA NO CADINHO DE UM FORNO DE CUBA METALÚRGICO, PAREDE EXTERNA DO CADINHO DE UM FORNO DE CUBA METALÚRGICO E ALTO-FORNO. A presente invenção refere-se a um processo de medição do nível de superfície de metal líquido (13) e do nível de superfície de escória (14) no cadinho (1) de um forno de cuba metalúrgico, compreendendo as seguintes etapas: - medição, em um ou mais pontos da parede externa (2) do cadinho, das seguintes variáveis: - a deformação circunferencial da citada parede externa (2) por meio de vários extensômetros (6) fixados sobre a blindagem (4) da parede externa (2) do cadinho; - a temperatura da mencionada parede externa (2) por meio de um ou mais sensores térmicos (7) fixados sobre a blindagem (4) da parede externa (2) do cadinho; - opcionalmente, medição da pressão circular ou pressão estática do vento quente dentro do forno; - introdução das ditas variáveis medidas em vários pontos da parede externa do cadinho na equação geral que rege a deformação circunferencial cuja solução é analítica, admitindo duas incógnitas, o nível de metal líquido e o nível global metal líquido-escória, levando em conta parâmetros fixos; e - resolução da referida equação e obtenção de uma solução analítica dando o nível de superfície de metal líquido (13) e do nível de superfície de escória (14) dentro do cadinho (1).
