Abstract

LA INVENCION SE REFIERE A UN PROCEDIMIENTO PARA LA CARBURACION GASEOSA DEL ACERO EN EL QUE LA PIEZA QUE SE HA DE CARBURAR EN UNA ATMOSFERA GASEOSA RICA EN CARBONO SE SOMETE, EN UNA PRIMERA FASE DE CARBURACION, A UNA OFERTA ALTA DE CARBONO EN EL LIMITE DE HOLLIN, Y EN EL QUE EN UNA FASE SUBSIGUIENTE DE DIFUSION, SE AJUSTA UNA OFERTA DE CARBONO DISMINUIDA CORRESPONDIENTE AL CONTENIDO LIMITE DE CARBONO CON LO QUE SE REGULA LA CARBURACION EN RELACION CON LAS DOS MAGNITUDES QUE SE PERSIGUEN, QUE SON EL CONTENIDO LIMITE DE CARBONO CR Y LA PROFUNDIDAD DE CARBURACION A1. PARA PROPONER UNA REGULACION INDEPENDIENTE DEL LIMITE DE CARBUROS CON LA QUE RESULTE POSIBLE CONSEGUIR CON FACILIDAD, SEGURIDAD Y REPRODUCIBILIDAD LA GRAFITA DE CARBONO QUE SE DESEA PARA LA PIEZA, SE SUGIERE QUE, ADEMAS DE LAS MAGNITUDES ANTERIORMENTE CITADAS, SE ESTABLEZCA OTRA MAGNITUD CARACTERISTICA PARA LA GRAFICA DE CARBONO QUE, AL SER ALCANZADA, HAGA DISMINUIR EL NIVEL DE CARBONO CARACTERISTICO DE LA FASE DE CARBURACION Y SEINICIE LA FASE DE DIFUSION.
