Abstract

"DISPOSITIVO DE MEDIçãO PARA DETERMINAR A ATIVIDADE DO OXIGêNIO EM FUNDIDOS DE METAL OU DE ESCóRIA". A presente invenção refere-se a um dispositivo de medição para determinação da atividade do oxigênio em metal ou escória fundidos com uma cabeça de medição, que é colocada em uma extremidade de um tubo transportador e na qual uma célula de medição eletroquímica é colocada. A célula de medição eletroquímica tem um pequeno tubo de eletrólito sólido, que é fechado em um lado e que contém em sua extremidade fechada um material de referência e um eletrodo, que se projeta da extremidade oposta do pequeno tubo de eletrólito sólido. O pequeno tubo de eletrólito sólido tem em sua superfície externa um revestimento feito de uma mistura de silicato de zircónio com um fluoreto. A cabeça de medição pode também ter um elemento térmico, e o dispositivo pode ser usado para determinar a concentração de silício e/ou de carbono no fundido, com base na medição da atividade do oxigênio.
