ものである。[Detailed description of the invention] 02 <Field of application of the present invention> The present invention is applicable to cooling plates, panels, cooling holders, etc. for cooling furnace walls used in vertical scouring or melting furnaces such as blast furnaces and cupolas. This invention relates to a mounting device for a cooling body for a vertical furnace.

It is fixed with nut 09'. Further, the seal surfaces 010 and 010' of both 7 langes are machined, and a gasket 08 is inserted between them to perform gas sealing.

し締めすることは作業上大変な仕事である。By the way, the bricks 04 of the furnace wall 05 show various behaviors due to the thermal influence during operation, and this behavior is caused by the tip 01 of the cooling plate 01.
Push down or push up 1 as shown by arrow a. As a result, various bending or compressive forces act from the base of the cooling plate 01 to the mounting 7 flange 06, resulting in a drawback that the performance of the gas seal N03 at the 7 flange surface deteriorates over time. Conventionally, this has been countered by retightening the bolts 09 and nuts 09', but retightening almost never stops the gas seal. Further, retightening a large number of bolts and nuts is a difficult task.

It is fixed to the fixed 7 flange on the side, and the circumferential protrusion is cut into the surface of the gasket to ensure gas sealing.

A continuous circumferential projection 12 is formed. 8 is a gasket inserted between the gas seal surface 10' of the fixed 7 lange 7 and the gas seal surface 10 of the mounting 7 lange 6.
, 9 is a bolt for attaching the mounting 7 flange 6 to the fixing flange 7, and 9' is a nut.

ることがより効果的である。In addition, the circumferential protrusion 12 is not only on the mounting flange 6 side, but also on the mounting flange 6 side.
It may be provided on the gas sealing surface 10' on the fixed 7 flange 7 side, or it may be provided only on the fixed 7 flange 7 side. Further, the circumferential protrusion 12 may also be located outside the bolt 9 and nut 91. However, in this case, it is preferable that the height of the bolt 9 and the nut 9' be lower than those located inside the bolt 9 and the nut 9' so as not to impede further tightening. Next, the shape of the circumferential protrusion 12 is determined by the material, thickness, shape, etc. of the gasket 8, but it is generally desirable that the tip shape of the circumferential protrusion 12 be as round as possible. Furthermore, the circumferential protrusion 1
Regarding the location and number of the flange 2, it is possible to set it arbitrarily depending on the weight of the cooling weight, the tightening force, and the shape and size of the flange 7, but it is more effective to provide it at least near the tightening part.

二重、三重の。Functions and Effects of the Embodiments of the Present Invention> As described above, the present invention has the circumferential protrusion 12 formed on the gas sealing surface 10 of the mounting 7 flange 6 of the cooling plate 1. When the lunge is tightened, the tip of the circumferential protrusion 12 bites into the surface of the gasket 8,
It performs the same action as the so-called 01J ring, and even if a force that inhibits the Gar seal is applied to the 7 lunges, the circumferential protrusion 12 will double or triple.

。Incidentally, when comparing the presence or absence of gas leakage caused by the amount of displacement (amount of movement) of the tip of the cooling plate 1 between the conventional method and the method of the present invention, it was found that in the case of the present invention, gas leakage occurred even if there was a movement of about 20 m+. No leakage was observed, but in the case of the conventional method, gas leakage was observed after a movement of about 5 cm.

It is pressed into contact with the surface of the iron fixed 7 lunge 7 and is in close contact with it.
