Abstract

EL INVENTO CONSISTE EN UN DISPOSITIVO PARA TRATAMIENTO TERMICO DE MERCANCIA DE FUNDICION METALICA CON UN RECIPIENTE METALURGICO PARA TOMA DE LA MERCANCIA DE FUNDICION Y UN DISPOSITIVO DE CALENTAMIENTO DE ARCO DE LUZ DE CORRIENTE CONTINUA SEPARADO O TRABAJANDO COMO COMPONENTE CON AL MENOS UN ELECTRODO COLOCADO EN LA PARTE SUPERIOR DE LA MERCANCIA DE FUNDICION Y CON AL MENOS UN CONTRAELECTRODO EN CONTACTO CON LA MERCANCIA DE FUNDICION. PARA PRODUCIR UN DISPOSITIVO SIN CUIDADOS FACILMENTE INTERCAMBIABLE QUE POSIBILITE UN CIERRE AUTOMATICO Y SEGURO DEL CONTRAELECTRODO EN LA CONDUCCION DE CORRIENTE PARA LA FUENTE DE ENERGIA, SE PROPONE QUE EN EL MANGUITO EXTERIOR (11) DEL RECIPIENTE METALURGICO (10) ESTE PREVISTO AL MENOS UN ELEMENTO (30) PARA TRANSMISION DE LA ENERGIA ELECTRICA AL CONTRAELECTRODO (22) Y MUESTRE UNA SUPERFICIE (31) QUE SE APOYA DURANTE EL PROCESO DE CALENTAMIENTO EN UNA SUPERFICIE (14) DE UN CONTRAELEMENTO (40) EN CONEXION CON LA FUENTE DE ENERGIA ELECTRICA (20) QUE SE POSICIONA CON MEDIOS MECANICOS (45).
