Abstract

Patente de Invenção: <B>"APARELHO PARA DESCARREGAR METAL DERRETIDO EM UM DISPOSITIVO DE FUNDIçãO E PROCESSO PARA USO".<D>Bocal ou tubo que é útil para o derrame de metal derretido, especialmente aço desoxidado de alumínio. O bocal é formado a partir de uma mistura de doloma e grafite a qual é ligada entre si em uma matriz carbonizada. Os bocais ou tubos fabricados de acordo com esta invenção possuem uma acentuada resistência ao choque térmico. Adicionalmente, os bocais ou tubos desta invenção resistem à formação de óxido de alumínio nos mesmos, quando nos mesmos, quando eles são usados para o derrame de aço desoxidado de alumínio derretido. Conseq³entemente, estes tubos ou bocais podem ser usados em um processo contínuo de fundição durante um longo período de tempo sem ter que periodicamente interromper o procedimento e mudar os tubos, na medida em que eles ficam bloqueados com o óxido de alumínio. Como resultado da resistência ao choque térmico, a etapa de pré-aquecimento comum é grandemente reduzida antes do contato do bocal com o metal derretido.
