Definitions

  • Buckling can be avoided by forming the hearth rolls as flat cylinders without crowns, however, the steel strip then meanders easily, as described above.
  • the inventors have carried out experiments in which the shape of the hearth rolls 50, and the width and thickness of the steel strip 60 were changed in various ways to determine the mechanism by which buckling is produced in the steel strip 60. As a result, they discovered that buckling occurs immediately before the steel strip 60 winds around the hearth roll 50, and again immediately after.
  • An extra-low carbon steel (C 0.003%) 0.7 mm thick and 1,280 mm wide was subjected to heat treatment at a rate of 200 m/min. The results are shown in Table 1, Fig. 18 and Fig. 19.
  • Example 1 (conventional annealing furnace), buckling was produced on the side advancing toward the hearth roll when the mean tensile stress in the steel strip was 0.4 kg/mm 2 .

Claims (6)

1. Kontinuierliche Glühvorrichtung für ein Stahlband (60) mit einer Vielzahl von konvexen Herdrollen (50, 52), welche horizontal im oberen und unteren Teil einer Hochtemperaturzone (30, 40) eines vertikalen kontinuierlichen Glühofens angeordnet sind und das Stahlband (60) auf und ab vertikal führen, wenn das Stahlband (60) den Ofen zum Erhitzen oder Durchglühen durchläuft, dadurch gekennzeichnet, daß mindestens eine zylindrische Rolle (70, 74, 78, 80) mindestens vor mehr als einer der konvexen Herdrollen (50, 52) auf der hinlaufenden Seite des Stahlbandes (60) relativ zu der konvexen Herdrolle (50, 52) vorgesehen ist und daß die zylindrische Rolle (70, 74, 78, 80) parallel zu der konvexen Herdrolle (50, 52) und in Druckkontakt mit dem Stahlband (60) angeordnet ist.
2. Kontinuierliche Glühvorrichtung nach Anspruch 1, dadurch gekennzeichnet, daß die zylindrische Rolle (70) in Kontakt mit der gleichen Oberfläche des Stahlbandes (60) steht, welche in Kontakt mit der Herdrolle (50, 52) auf der hinlaufenden Seite des Stahlbandes (60) relativ zu der Herdrolle (50, 52) ist (Fig. 9).
3. Kontinuierliche Glühvorrichtung nach Anspruch 1, dadurch gekennzeichnet, daß jede zylindrische Rolle (70, 72) jeweils in Kontakt mit der gleichen Oberfläche des Stahlbandes (60) angeordnet ist, welche in Kontakt mit der Herdrolle (50, 52) ist, sowohl auf der hinlaufenden wie auf der ablaufenden Seite des Stahlbandes (60) relativ zu der Herdrolle (50, 52) (Fig. 10).
4. Kontinuierliche Glühvorrichtung nach Anspruch 1, dadurch gekennzeichnet, daß die zylindrische Rolle (74) in Kontakt mit der gegenüberliegenden Oberfläche des Stahlbandes (60) steht, welche nicht in Kontakt mit der Herdrolle (50, 52) ist, auf der hinlaufenden Seite des Stahlbandes (60) relativ zu der Herdrolle (50, 52) (Fig. 11).
5. Kontinuierliche Glühvorrichtung nach Anspruch 1, dadurch gekennzeichnet, daß jede zylindrische Rolle (74, 70) jeweils in Kontakt mit der gegenüberliegenden Oberfläche des Stahlbandes (60) steht, welche nicht in Kontakt mit der Herdrolle (50, 52) ist, sowohl auf der hinlaufenden wie auf der ablaufenden Seite des Stahlbandes (60) relativ zu der Herdrolle (50, 52) (Fig. 12).
6. Kontinuierliche Glühvorrichtung nach Anspruch 1, dadurch gekennzeichnet, daß zwei Paare von zylindrischen Rollen (78, 80; 82, 84) jeweils auf der hinlaufenden und ablaufenden Seite des Stahlbandes (60) relativ zu der Herdrolle (50, 52) angeordnet sind und daß jedes Paar der zylindrischen Rollen (78, 80; 82, 84) den gleichen Teil des Stahlbandes (60) von gegenüberliegenden Oberflächen aus in Druckkontakt mit dem Stahlband (60) zwischen sich nimmt (Fig. 13).
