Abstract

2.1 PROCEDIMIENTOS CONOCIDOS POR LOS QUE SE CONSIGUE UNA CRISTALIZACION POR ENFRIAMIENTO DE UNA PARED DE UN DEPOSITO O SEMEJANTE CONTIGUA A UNA FUSION, SOLO PUEDE FUNCIONAR DISCONTINUAMENTE PARA VOLVER A DESPRENDERSE DE LA CAPA DE CRISTAL CONSTITUIDA EN LAS PAREDES DEL DEPOSITO. 2.2 SE PROPONE UNA INSTALACION DE DOBLE BANDA PROVISTA DE DOS BANDAS SIN FIN ROTANDO EN EL MISMO SENTIDO CUYOS RAMALES CONDUCIDOS VUELTOS EL UNO AL OTRO FORMAN UNA HENDIDURA PARA LA FUSION CONDUCIDA POR UNA BANDA. EL RAMAL INFERIOR DE LA BANDA SUPERIOR ENTRA EN MOVIMIENTO CON LA SUPERFICIE DE LA FUSION. SI ESTE RAMAL SE ENFRIA CORRESPONDIENTEMENTE, ENTONCES SE QUITA LA CAPA DE CRISTALIZACION QUE SE ESTA FORMANDO Y SE EXTRAE DE LA HENDIDURA Y HACIA AFUERA DE LA MISMA. 2.3 UTILIZACION PARA SOLIDIFICACION O PARA PURIFICACION DE FUSIONES DE MATERIAS QUIMICAS.
