Abstract

<B>PROCESSO E APARELHO PARA DETECTAR ESCóRIA<D> São fornecidos um aparelho e um processo para detectar escória (19) em um fluxo de metal fundido (1) conduzido através de um aro reforço de colherão (11). No aparelho, primeiro (31) e segundo (33) pinos condutores são montados um ao lado do outro em uma parede (22) do aro de reforço de colherão (11), o primeiro (31) estando em contato com o fluxo de metal fundido (1), porém isolado eletricamente tanto da parede (22) como do segundo pino condutor (33), o segundo (33) estando em contato elétrico tanto com a parede como com o fluxo de metal fundido (1). Um voltímetro (34) é conectado entre os dois pinos condutores (31, 33) para detectar diferenças no potencial elétrico entre os mesmos à medida que metal fundido (1) flui através do aro de reforço (11). Mudanças abruptas em potencial ocasionadas pela passagem de uma interface de metal (1) escória (19) através do aro de reforço
