Abstract

MéTODOS PARA REMOVER UM MODELO TEMPORáRIO DE UM MOLDE REFRATáRIO E PARA REMOVER UM MODELO TEMPORáRIO CONECTADO A UM SITO TEMPORáRIO OCO DE DENTRO DE UM MOLDE REFRATáRIO PERMEáVEL A GáS, E, APARELHO PARA REMOVER UM MODELO TEMPORáRIO DE DENTRO DE UM MOLDE REFRATáRIO é provido um método para remover um modelo temporário, tal como cera ou outro material do modelo fundível, que reside dentro de um molde refratário, descarregando vapor condensável, tal como vapor condensável, tal como vapor d'água, dentro do molde para fazer contato e fundir o modelo enquanto o exterior do molde é submetido a uma atmosfera de gás que não condensa tal como ar fora do molde, em que o vapor condensável dentro do molde e o lado de fora da atmosfera do molde estão substancialmente na mesma pressão. Vapor condensável é condensado dentro do molde onde o vapor fez contato com o modelo, enquanto o exterior do molde permanece livre de condensados. O vapor condensado e material do modelo fundido são drenados para fora do molde. O vapor condensado pode ser descartado inicialmente dentro de um jito oco de uma montagem do modelo temporário para fundir o jito e, em seguida, dentro do molde para fundir os modelos da montagem do modelo. O método permite a remoção dos materiais do modelo temporário dos moldes de qualquer espessura e reduz o trincamento do molde durante a remoção do modelo.
