Abstract

"MéTODO DE PRODUçãO PARA LINGOTAMENTO CONTìNUO DE PRODUTO DE AçO". A presente invenção refere-se a um método de produção para um produto de aço lingotado continuamente compreendendo as etapas de: detectar a posição da extremidade de cratera do produto por um método para medição do estado de solidificação do produto lingotado continuamente usando-se um sensor colocado de forma a não estar em contato com o produto; e controlar pelo menos uma condição selecionada entre as condições de velocidade do lingotamento e da quantidade de água do resfriamento secundário com base na posição detectada da extremidade de cratera, o método para a medição do estado de solidificação do produto lingotado continuamente compreendendo as etapas de: resfriar o produto até que uma porção de sua camada de superfície seja <244> transformada; transmitir ondas transversais das ondas ultra-sónicas eletromagnéticas para o produto resfriado; receber o sinal após o sinal de transmissão ter-se propagado no produto; e julgar o estado de solidificação do produto com base no sinal recebido.
