Abstract

L'invention est relative à un mandrin de forgeage. Selon l'invention, le corps du mandrin comprend une paroi extérieure faite d'une matière à haute résistance à la chaleur, de préférence d'un alliage à base de nickel ou de cobalt, qui entoure le manchon porteur en acier d'outillage ou autres matières d'oeuvre analogues, à haute résistance mecanique, tandis qu'on utilise comme fluide de refroidissement un mélange réglable d'air et d'eau. Le mandrin présente une résistance élevée à l'usure pour des températures superficielles atteignant 900 degrés C, et peut être refroidi à la température désirée.
