本考案は、鋼板の如き金属板の加熱炉における
熱交換器の改良構造に関する。[Detailed Description of the Invention] Technical Field The present invention relates to an improved structure of a heat exchanger in a heating furnace for metal plates such as steel plates.

の問題も生じる。Prior Art As shown in FIG. 1, a heat exchanger in a conventional heating furnace is arranged above a red-hot steel plate 1, a heat receiving plate 2 and a top plate 3 are arranged in a box shape, and a cold air inlet 4 is provided inside the heat exchanger. It is designed to send cold air 6. The heat receiving plate 2 receives the radiant heat from the red-hot steel plate 1, moves it with cold air, and collects it from the outlet side 5. In this case, the temperature of the heat receiving plate 2 is constantly balanced between heat input and heat output, and locally becomes a constant high temperature. If the upper surface of the upper surface plate 3 is kept warm with a heat insulating material, the temperature of the upper surface of the upper surface plate 3 will be approximately equal to that of the air in that area. Therefore, the temperature difference between the heat receiving plate 2 and the top plate 3 reaches approximately 200 to 500°C.
If both were made of the same material, the difference in temperature would cause a difference in thermal expansion and contraction, causing thermal deformation and making it unusable. In addition, in heat exchangers for industrial furnaces, the air pressure used is 500~
It is about 900Kg/m 2 , and there is also a problem in strength against liquid pressure.

is a heat receiving plate and 8 is a top cover. A plurality of fins 9 are vertically welded to the upper surface of the heat receiving plate 7. A presser plate 10 is disposed on the upper surface of the upper cover 8 at a proper position, and a gasket 11 is inserted between the presser plate 10 and the upper cover 8. A hanging bolt 12 is provided passing through the presser plate 10 and the top cover 8, and a tip hook 13 of the hanging bolt 12 is hung in a hole 14 provided in the fin 9. The upper part of the hanging bolt 12 is elastically attached to the holding plate 10 via a spring 15, and the collar 16 is filled with a gland packing 17.

する。 The present invention has the above-described configuration and allows cold air to pass between the fins 9. However, as is clear from the above explanation, the heat receiving plate 7 and the top cover 8 are relatively misaligned due to the temperature difference. . This deviation is absorbed by the contact surface between the packing 11 and the top cover 8.
In addition, the fins 9 quickly transfer the heat of the heat receiving plate 7 to the top cover 8 to reduce the temperature difference between the two, and are always elastically pressed against the top cover 8 by the hanging bolts 12, so that the fins 9 and the top cover This prevents a change in heat transfer performance due to a gap between the cover 8 and the cover 8. Also, Grand Packkin 17
prevents air from leaking in the axial direction of the hanging bolt 9.
