Abstract

Es wird ein Turmofen zur Wärmebehandlung von Metallbändern mit einem Vorwärmabschnitt (3) und einem daran nach oben anschließenden, ein vom Vorwärmabschnitt (3) gesondertes Gehäuse (4) bildenden Hochtemperaturabschnitt (5) beschrieben, wobei der mit einer vorzugsweise gasbeheizten Muffel (7) ausgerüstete Vorwärmabschnitt (3) einen oben in die Muffel (7) eingesetzten Anschlußstopfen (6) aus wärmeisolierendem Werkstoff für den Hochtemperaturabschnitt (5) aufweist. Um vorteilhafte Konstruktionsbedingungen zu schaffen, wird vorgeschlagen, daß der Hochtemperaturabschnitt (5) ebenfalls mit einer vorzugsweise gasbeheizten Muffel (12) versehen ist, die den Anschlußstopfen (6) außen umschließt und an diesen vorzugsweise über eine Flüssigkeitsdichtung (14) gasdicht anschließt.

Figure 00000001
A tower furnace for the heat treatment of metal strips with a preheating section (3) and an adjoining upward one, a high-temperature section (5) forming a housing (4) separate from the preheating section (3), is described, the one equipped with a preferably gas-heated muffle (7) Pre-heating section (3) has a plug (6) made of heat-insulating material for the high-temperature section (5) inserted into the muffle (7) at the top. In order to create advantageous construction conditions, it is proposed that the high-temperature section (5) also be provided with a preferably gas-heated muffle (12) which surrounds the connector plug (6) on the outside and connects to it preferably gas-tight via a liquid seal (14).
