Abstract

PROCEDIMIENTO Y DISPOSITIVO PARA LA FUSION DE MATERIALES VITREOS. EL PROCEDIMIENTO CONSISTE EN REGULAR LA POTENCIA TERMICA SUMINISTRADA POR VIA ELECTRICA A LA MASA VITREA. LA INTRODUCCION DE LA POTENCIA ELECTRICA SE EFECTUA POR INTERVALOS DE TIEMPO CONSTITUIDOS POR UN NUMERO ENTERO DE PERIODOS DE LA ONDA DE TENSION QUE ACTUA SOBRE LOS ELECTRODOS. EL DISPOSITIVO ESTA CONSTITUIDO POR: UN ELEMENTO ELECTRONICO Y/O ELECTROMECANICO DE INTERRUPCION Y RESTABLECIMIENTO DE LA POTENCIA DE LA INSTALACION CONSISTENTE EN PARES DE TIRISTORES EN ANTIPARALELO CON LOS CORRESPONDIENTES TRANSFORMADORES DE IMPULSOS; UN SEGUNDO ELEMENTO PARA EXCITAR EL PRIMER ELEMENTO Y DOTADO DE UNIDADES LOGICAS.
