Abstract
MéTODO E EQUIPAMENTO PARA MEDIçãO DA TEMPERATURA DE UM BANHO DE METAL FUNDIDO. A invenção refere-se a um método pare medição da temperatura de um banho de metal fundido por meio de uma fibra ótica cercada por um revestimento. A fibra ótica é imersa no banho de material fundido e a radiação absorvida pela fibra ótica no banho de material fundido é alimentada a um detector, onde a fibra ótica é aquecida quando imersa no banho de material fundido. A curva de aquecimento da fibra ótica tem pelo menos um ponto P(t~ o~, T~ o~), onde o aumento <30>T~ 1~, na temperatura T da fibra ótica sobre o tempo <30>t em um primeiro intervalo de tempo t~ o~-<39>t até a temperatura T~ 0~ é menor que o aumento <39>T~ 2~ na temperatura da fibra ótica sobre o tempo <39>t em um segundo intervalo de tempo imediatamente seguinte t~ o~+<39>t.
