Abstract

FABRICACION DE UN ELEMENTO DE CALEFACCION ELECTRICA TUBULAR, EN EL QUE LA RESISTENCIA ELECTRICA ES UNA ALEACION DE FE-CR-A1 QUE ESTA EMPOTRADA EN UNA MASA DE OXIDO DE MAGNESIO. CONSISTENTE EN PREPARAR UN ALAMBRE DE RESISTENCIA A PARTIR DE UNA ALEACION QUE COMRENDE 12 A 25 POR 100 EN PESO DE CR, 3 A 6 POR 100 DE A1, 0,01 A 1 POR 100 DE FE Y EL RESTO DE HIERRO Y PEQUEÑAS CANTIDADES DE OTRAS SUSTANCIAS; POR EJEMPLO, SI, MN Y CO, E IMPUREZAS USUALES EN UNA CANTIDAD TOTAL QUE NO EXCEDE DE UN 2 POR 100. SE ARROLLA EN ESPIRAL EL ALAMBRE PARA FORMAR UNA BOBINA QUE ES PROVISTA OPCIONALMENTE DE CONECTADORES TERMINALES, INTRODUCIENDOSE LA BOBINA CONCENTRICAMENTE EN UNA ENVUELTA METALICA TUBULAR EXTERIOR QUE TIENE UN DIAMETRO INTERNO MAYOR QUE EL EXTERNO DE LA BOBINA. SE RELLENA LA ENVUELTA METALICA CON UN MATERIAL PULVERULENTO ELECTRICAMENTE AISLANTE, PREFERIBLEMENTE MGO, Y SE COMPRIME EL ELEMENTO TUBULAR PREPARADO, PUDIENDOSE CERRAR HERMETICAMENE LOS EXTREMOS DEL ELEMENTO.
