Abstract

Un montaje de boquilla de corte y un método asociado para elaborar el mismo incluyen una boquilla que tiene un orificio central que se extiende a lo largo de un eje longitudinal a través del cual se descarga un gas de corte asociado. Una pluralidad de orificios de gas de combustión espaciados están dispuestos alrededor del orificio central, y los conductos de precalentamiento están dispuestos alrededor del orificio central y los orificios de gas de combustión. Una tuerca de retención recibe al menos una porción de la boquilla en su interior, y la tuerca de retención incluye una cubierta que se extiende axialmente hacia afuera desde un extremo de descarga de la boquilla. Al menos uno de la superficie interna de la cubierta y los conductos de precalentamiento adicionales están inclinados hacia dentro hacia el eje longitudinal. Los orificios de gas de combustión y los conductos de precalentamiento tienen cada uno la misma dimensión de la sección transversal, y se proporciona el doble del número de conductos de precalentamiento que los orificios de gas de combustión.
