Abstract

Forno ad atmosfera controllato particolarmente per il preriscaldamento di matrici di estrusione di alluminio e sue leghe, la peculiarità del quale consiste nel comprendere un telaio di supporto che delimita, in corrispondenza di una porzione di una parete laterale, almeno una camera chiudibile a tenuta verso l'ambiente esterno. Il trovato comprende inoltre in corrispondenza di della camera un portello apribile verso l'esterno, che presenta mezzi di supporto di un pezzo da preriscaldare. Il trovato comprende infine mezzi di riscaldamento della camere.Controlled atmosphere furnace particularly for the preheating of extrusion dies of aluminum and its alloys, the peculiarity of which consists in comprising a support frame which defines, at a portion of a side wall, at least one chamber which can be closed seal external environment. The invention further comprises at the chamber a door which can be opened outwards, which has support means for a piece to be preheated. Finally, the invention comprises means for heating the chambers.
