0 mitPATENTANSPRÜCHE : 1. Verfahren für die zunderfreie Erhitzung von Metallgegenständen in einem Schachtofen, dadurch gekennzeichnet, dass der Gegenstand (17) zunächst in einem Vorwärmeraum (11) auf eine Temperatur erhitzt wird, bei der keine Zunderbildung eintritt, und auf die Höchsttemperatur in einem wärmespeichernden Arbeitsraum (11) unter Schutzgasatmosphäre nacherhitzt wird, wobei in dem Arbeitsraum eine Wärmespeicherwand (6) von beiden Seiten auf eine hohe Temperatur erhitzt wird, die die Ausstrahlung der zum Erhitzen des Gegenstandes notwendigen Wärme gewährleistet. 0 with PATENT CLAIMS: 1. A method for the scale-free heating of metal objects in a shaft furnace, characterized in that the object (17) is first heated in a preheating room (11) to a temperature at which no scale formation occurs and to the maximum temperature in a heat-storing work room ( 11) is post-heated under a protective gas atmosphere, a heat storage wall (6) in the working space being heated from both sides to a high temperature, which ensures that the heat required to heat the object is emitted. 2. Einrichtung zur Durchführung des Verfahrens nach Anspruch 1, dadurch gekennzeichnet, dass der Schachtofen aus dem wärmespeichernden Arbeitsraum (1), der im oberen und unteren Teil mit Brennern (2) und in seiner Mitte mit Abzugskanälen (3) versehen ist, der Wärmespeicherwand (6), die von der Ofenausmauerung (7) durch einen Abzugsraum (8) getrennt ist und aus dem Vorwärmeraum (11) besteht, in welchem vom Abzugsraum (8) oben ein Kanal (10) in seinen oberen Teil und unten ein Kanal (14) in seinen unteren Teil einmündet. 2. Device for carrying out the method according to claim 1, characterized in that the shaft furnace from the heat-storing work space (1), which is provided in the upper and lower part with burners (2) and in its center with exhaust ducts (3), the heat storage wall (6), which is separated from the furnace lining (7) by a fume cupboard (8) and consists of the preheating room (11), in which from the fume cupboard (8) above a duct (10) in its upper part and below a duct ( 14) opens into its lower part.
