Abstract

na presente invenção, um sensor da superfície do metal fundido é proporcionado em uma carga, e a superfície do metal fundido na carga é mantida em uma posição mais alta do que a superfície do metal fundido em um forno de espera, com o que a quantidade de movimento do metal fundido é minimizada, uma nova oxidação do metal fundido em virtude de distúrbio da superfície de metal fundido ser evitada, e o sedimento no forno de espera é impedido de ser agitado.
