Description of the Related Art Conventionally, in a continuous furnace in which a material such as a strip is continuously heat-treated, an atmospheric gas in the furnace is prevented from flowing out to a charging port and an extraction port of the furnace, and outside air is prevented from entering the furnace. A sealing device is provided for the sealing. As this sealing device, those disclosed in JP-B-63-38410 and JP-A-4-202715 are known. These two seal devices are arranged with a belt-shaped felt seal member facing the loading port and the extraction port,
The material passes between these felts,
It is called a fixed sealing device.

しなければならないという問題があった。For the felt of the fixed sealing device, natural wool is used, which satisfies conditions such as not easily damaging the strip material, not hardening by heat, and having good slipperiness with respect to the material. However, since the material passes while contacting the same portion of the felt, there is a problem that only the contact portion of the felt is extremely worn and the sealing performance is reduced in a short period of time. In addition, there is a problem that the steel slab or the like accumulated in the contact portion damages the material passing between the felts, so that the felt must be replaced frequently.

む。[0004] As a sealing device for solving the above problem, a sealing roll device disclosed in Japanese Utility Model Publication No. 60-40599 has been proposed. This seal roll device is configured by disposing a pair of rolls for sandwiching a material at a charging port and an extraction port of a continuous furnace, and bonding a felt made of natural wool to an outer periphery of these rolls. In addition, in this seal roll device, the roll is rotated at the same speed as the material transport speed to prevent the felt from being partially worn, and the steel pieces accumulated at the contact portion of the felt reduce the material transport speed and the roll rotational speed. To prevent the material from being damaged due to the speed difference. Therefore, the sealing property is maintained for a long time, and the number of maintenances such as felt replacement is reduced.

A sheet-like felt layer 18 is overlaid on the sheet. Then, the fibers of the felt layer 18 are penetrated through the backup layer 24, the low-shrink material layer 22, and the high-shrink material layer 20 by needle punching and are entangled with the fibers of the respective layers to be mechanically joined to each other to form a seal member 1 having a multilayer structure.
Get 4. In addition, the sealing member 14 is
0, the seal member 14 formed in a cylindrical shape is used.
Is formed slightly larger than the outer diameter of the shaft core 12 so that it can be easily mounted on the shaft core 12.

By supplying the hot air or steam, the heat shrinkable material layer 16 is efficiently heat shrunk and fixed to the shaft core 12. When replacing the seal member 14, the old seal member 14 is cut off with a cutter or the like and removed from the shaft core 12, and the new seal member 14 is fixed to the shaft core 12 as described above. Therefore, the seal member 14 can be easily replaced on site and the shaft 12 can be reused many times. In addition, the sealing member 1
The hot air or steam may be supplied to the inner space 26 of the shaft core 12 when the heat shrinkage 4 is contracted.

In a seal roll using this seal member, the heat-shrinkable material layer is fixed to the shaft core by heat-shrinking. Therefore, even if the furnace is used in a high-temperature atmosphere, no gas is generated due to the vaporization of the binder, so that the furnace atmosphere can be maintained in a good state. In addition, the old seal member can be easily removed by cutting the old seal member with a cutter. In addition, the seal member can be easily mounted simply by applying heat to the shaft core so that the shaft core can be reused. Becomes
