Abstract

UN HORNO DE VACIO PARA LA CARBURACION POR PLASMA DE PIEZAS METALICAS EN UN CAMPO ELECTRICO GENERADO ARTIFICIALMENTE MEDIANTE UN GAS QUE CONTENGA CARBONO, DISPONE DE UN DISPOSITIVO ELECTRICO CALEFACTOR (11), UNA BOMBA DE VACIO (24) PARA GENERAR UN VACIO EN LA CAMARA CALEFACTORA (6) ASI COMO DE ORIFICIOS DE ENTRADA DE GAS (9) MEDIANTE LOS QUE SE ALIMENTA EL GAS REFRIGERANTE DE LA CARGA (7) SUMINISTRADO POR UN SOPLADOR (22) Y CONDUCIDO A TRAVES DE UN INTERCAMBIADOR DE CALOR (21). PARA CONSEGUIR UN HORNO DE VACIO MAS PEQUEÑO QUE LOS HORNOS DE VACIO CONOCIDOS, LA CARCASA DEL HORNO (1) CONFIGURADA COMO RECEPTACULO DE PRESION ESTA DISEÑADA EN ATENCION A SU CARGA POR PRESION ADMISIBLE ASI COMO EL ACCIONAMIENTO (4) DEL SOPLADOR (21) EN ATENCION A LA PRESION DE GAS ALCANZABLE AL ENFRIAR LA CARGA (7) A UN PRESION DE 10 BARES COMO MINIMO. ADEMAS, LOS ORIFICIOS DE ENTRADA DE GAS (9) QUE CONDUCEN EL GAS REFRIGERANTE ESTAN DISPUESTOS EN LA CAMARA CALEFACTORA (6) Y ORIENTADOS HACIA LA CARGA (7).
