Abstract

En el caso de una corona de perforación (1) para el horadado, en particular el horadado mediante percusión y rotación de un agujero, especialmente un agujero de piquera de un alto horno, consistiendo la corona de perforación (1) de un cabezal de perforación (4) con una pluralidad de insertos de material duro o bien de metal duro (6), y un cuerpo de base (2) para la unión con un elemento motriz, etc., para el accionamiento o la impulsión de la corona de perforación (1), estando alojados los insertos de material duro o bien de metal duro (6) en orificios o bien en aberturas (5) del cabezal de perforación (4), se prevé que por lo menos un inserto de material duro o bien de metal duro (6) en el extremo alojado en el cabezal de perforación (4) esté configurado por lo menos parcialmente con un contorno superficial curvado o bien abovedado (11), que actúa conjuntamente con una superficie curvada o bien abovedada complementaria del cabezal de perforación (4) y/o del cuerpo de base (2), por medio de lo cual se puede transmitir aún en el caso de un aflojamiento de los insertos de material duro o bien de metal duro (6) de forma confiable la energía de impacto requerida para una capacidad de horadado adecuada.
