Abstract (en)
[origin: EP0754768A1] The furnace, (pref. a vacuum furnace) has a housing (1) accommodating a heating chamber (6) and an intermediate space divided into outer and inner chambers (4, 11). It is provided with a gas cooling system (9) which is connected with the heating chamber via the chambers (4, 11) and closable openings (12) in the wall (5) of the heating chamber. The chamber (4) serves as a pressure chamber for the cooling gas fan (3), while the chamber (11) serves as a suction chamber for this fan. Axially movable gas delivery units (15) allow the heating chamber to be isolated from the pressure and suction chambers.
