Abstract

Bei einem Verfahren zum Wärmebehandeln von insbe­ sondere metallischen Werkstücken in einer eine entspre­ chende Atmosphäre enthaltenen Ofenkammer (21) wird die Atmosphäre auf die jeweilige Prozeßtemperatur aufgeheizt. Die Werkstücke werden in die Ofenkammer (21) eingegeben und verbleiben dort für eine vorbestimmte Zeit. Gleichzeitig werden die Zustandsgrößen und die Zusammensetzung der Ofenatmosphäre geregelt bzw. gesteuert.
Um quasi gleichzeitig Chargen behandeln zu können, die eine unterschiedliche Verweilzeit erfordern, wird jede Charge nach Ablauf einer für sie spezifischen Verweilzeit in der Ofen­ kammer (21) von den übrigen Chargen unabhängig aus der Ofenkammer entnommen.
