Abstract

"APARELHO E MéTODO PARA MEDIR A TEMPERATURA DE METAL FUNDIDO".<UM> Campo Técnico<MV> A invenção proporciona um sistema de resfriamento para proteger uma fibra de imagem e um dispositivo de formação de imagem de influências térmicas e um aparelho de medição de temperatura de um metal fundido capaz de ser facilmente controlado e medir estavelmente a temperatura. O aparelho de medição de temperatura de um metal fundido compreende quatro porções conectáveis de uma porção de bocal, uma porção de introdução de gás de purga/ resfriamento, uma porção de encaixe de fibra de imagem com vidraça e um tubo de proteção de fibra de imagem. Uma distância de uma extremidade distal de bocal como uma porção de introdução de luz de radiação térmica a uma porção de recepção de luz em uma extremidade distal de fibra de imagem é encurtada por um bocal de tubo duplo de modo que uma quantidade maior de luz de radiação térmica pode ser recebida.
