This type of plate-fixed furnace cover sealing device uses one end of a band-shaped spring plate fixed to the oven cover body, and a band-shaped seal member is attached to the free end of the band-shaped spring plate. For example, JP-A-57-
Compared to the knife-edge type sealing member installed along the side of the furnace lid as shown in Publication No. 148183, the positional relationship between the furnace lid body and the furnace frame is affected by heat distortion of the furnace lid, etc. It is possible to avoid the deterioration of sealing performance due to changes in the temperature, and also to avoid the inconvenience of tar leaking out from the sliding part between the side of the furnace cover body and the sealing member that slides along the side. It is useful in this respect.

ような問題があつた。 However, as shown in FIG. 9, in the conventional type, the free end side of the band-shaped spring plate 6 attached to the furnace cover main body 2a with a presser plate 10 and bolts/nuts 11 is provided at an angle approximately perpendicular to the protruding portion of the spring plate 6. The belt-shaped sealing member 7 is welded so that the flat pressing surface of the pressing member 15, which is biased by the spring 14 in the case 24 attached to the furnace lid body 2a, is brought into contact with the sealing member. Seal member 7 Furnace frame 4
Since the furnace lid body 2a and the furnace frame 4 were pressed against each other to prevent gas leakage from between the furnace lid body 2a and the furnace frame 4, the following problems occurred.

That is, the furnace lid main body 2a may be damaged due to thermal distortion of the furnace lid, etc.
When the positional relationship between the frame 4 and the furnace frame 4 changes, the spring plate 6 is bent and deformed as the spring 14 is deformed, as shown by dotted lines and chain lines in FIG.
However, as the spring plate 6 is bent and deformed, the spring plate 6 remains substantially perpendicular to the protruding portion thereof, and swings into an inclined position, which deviates from the predetermined position with respect to the furnace frame 4, and the sealing member 7 and the furnace Seal defects were likely to occur between the frames 4, leaving room for further improvement.

後者S2を前者S1より長くしてある。 In the pressing tool 8 located between the upper and lower bolts 3a and 3b, as shown in FIG. Case 12
A gutter-shaped downwardly extending portion 12a is formed at the lower end of the furnace lid body 2a than the sealing member 7. In addition, in the pressing tool 9 located above the bolt 3a and below the bolt 3b, as shown in FIG. At the same time, a gutter-shaped downwardly extending portion 13a is formed at the lower end of the case 13 so as to be located further from the furnace lid body 2a than the sealing member 7. The edges of both extensions 12a and 13a on the sealing member 7 side are arranged close to the sealing member 7 with a gap for absorbing manufacturing errors of about 1 mm, so that the sealing member 7 is Stopper to regulate inclination
S 1 and S 2 , and in consideration of extrusion of a large seal member 7 in an abnormal furnace, the latter stopper S 2 is made longer than the former stopper S 1 .

好適な状態に維持される。 In other words, as shown in FIG. 4, thermal distortion of the furnace cover 2 causes the sealing member 7 between the upper and lower bolts 3a and 3b to deform so as to be pressed against the furnace frame 4, and the bolt 3
The sealing member 7 deforms away from the furnace frame 4 above a and below the bolt 3b. Therefore, between the upper and lower bolts 3a and 3b, the spring 14 is shortened, the leaf spring 6 is deflected and deformed toward the pressing tool 8, and the sealing member 7 is tilted toward the furnace lid main body 2a as it approaches the pressing tool 8. However, the stopper S1 restricts the inclination of the seal member 7, and the attitude of the seal member 7 relative to the furnace frame 4 is maintained in a state suitable for gas sealing. Moreover, above the bolt 3a and below the bolt 3b, the spring 14 is extended, the leaf spring 6 is bent and deformed toward the furnace frame 4, and the sealing member 7 is in an inclined position such that the closer to the furnace frame 4, the closer to the furnace lid main body 2a. When the seal member 7 is about to open, the stopper S2 restricts the inclination of the seal member 7, and the attitude of the seal member 7 with respect to the furnace frame 4 is maintained in a state suitable for gas sealing.
