Abstract

UN APARATO PARA FUNDIR MATERIAL Y CALENTAR INDUCTIVAMETNE MATERIAL EN FUSION, QUE COMPRENDE: UN RECIPIENTE REFRACTARIO COMPUESTO DE UNA PLURALIDAD DE PIEZAS NO METALICAS QUE DEFINEN UNA CAVIDAD ADAPATADA PARA CONTENER UN CUERPO DE MATERIAL EN FUSION; UNA VAINA METALICA QUE PROVEE UNA PORCION PRINCIPAL DEL RECIPIENTE QUE DEFINE UN CIRCUITO ELECTRICO ALREDEDOR DEL RECIPIENTE Y QUE PRESENTAUNA BARRERA A LAS PERDIDAS DESDE EL RECIPIENTE: MEDIOS PARA APLICAR FUERZAS DE COMPRESION SOBRE EL RECIPIENTE POR MEDIO DE LA VAINA; Y MEDIOS DE SUMINISTRO A LA VAINA DE CORRIENTE ELECTRICA ALTERNA SUFICIENTE PARA INDUCIR CORRIENTES ELECTRICAS EN EL MATERIAL EN FUSION CONTENIDO EN EL RECIPIENTE DE MANERA QUE SE CALIENTA EL MATERIAL. LA VAINA ESTA CONFIGURADA COMO UN CILINDRO QUE TIENE UNA HENDIDURA A LO LARGO DE SU LONGITUD.AN APPARATUS FOR MELTING MATERIAL AND INDUCTIVELY HEATING MATERIAL IN MELTING, INCLUDING: A REFRACTORY CONTAINER COMPOSED OF A PLURALITY OF NON-METAL PIECES DEFINING A CAVITY ADAPTED TO CONTAIN A BODY OF MATERIAL IN MELTING; A METAL SHEATH THAT PROVIDES A MAIN PORTION OF THE CONTAINER DEFINING AN ELECTRICAL CIRCUIT AROUND THE CONTAINER AND PRESENTING A BARRIER TO LOSSES FROM THE CONTAINER: MEANS OF APPLYING COMPRESSION FORCES OVER THE CONTAINER; AND MEANS OF SUPPLY TO THE ALTERNATING ELECTRIC CURRENT SHEATH ENOUGH TO INDUCE ELECTRICAL CURRENTS IN THE MELTING MATERIAL CONTAINED IN THE CONTAINER SO THAT THE MATERIAL IS HEATED. THE SHEATH IS CONFIGURED AS A CYLINDER WHICH HAS A CRACK ALONG ITS LENGTH.
