Abstract

Patente de Invenção:<B>"MéTODO PARA PREVENIR CONTATO DE OXIGêNIO COM UMA FUNDIçãO DE METAL"<D>. Em um método para prevenir contato de oxigênio com uma fundição de metal, o qual a fundição de metal flui dentro de uma câmara de fundição limitada por paredes (1, 2, 13) e deixa esta câmara como uma corrente. No sentido de prevenir completamente o contato do oxigênio com a fundição de metal e assim a reoxidação, o oxigênio tentando entrar via quaisquer intervalos (18) entre as paredes (1, 2, 13) e/ou aderindo às parades (1, 2) é reagido para formar um composto que não é prejudicial à fundição de metal (20).
