Abstract

"SONDA DE BANHO CRIOLìTICO FUNDIDO". A presente invenção refere-se a um método e aparelho para medir com precisão o superaquecimento, a relação de banho e a concentração de alumina em um banho de fusão de alumínio. Em uma concretização, uma sonda reutilizável (2) determina a temperatura do banho e o superaquecimento da amostra do banho. Em outras concretizações, a sonda (2) também determina a composição do banho incluindo a relação de criolita do banho e a concentração de alumina.
