結果炉蓋の寿命が短くなる問題があつた。[Detailed description of the invention] The present invention relates to a furnace cover for a soaking furnace.
The lid of the soaking furnace is exposed to high temperatures of about 1200 to 1400 degrees C. If ceramic fiber is used under such high temperature conditions, large cracks will randomly occur in the width direction of the lid, and shrinkage of the ceramic fiber will also occur in the longitudinal direction of the lid at the rod support metal position and at the midpoint between them. Furthermore, since there is no backup material at the top of the ceramic fiber, internal combustion gases will pass through the cracks and shrinkage and reach the iron shell, resulting in a shortened life of the lid.

したことを、主たる特徴としている。 To achieve this purpose, the present invention firstly forcibly compresses a blanket made of compressible fireproof insulation fibers (for example, "Fine Flex Blanket" manufactured by Nippon Asbestos Co., Ltd.), and In order to ensure compression and to simplify construction, a large number of stacked rods are arranged in series with the rod support member serving as a compression connection seat, and in order to prevent shrinkage between the second blanket layers. Firstly, the blankets are integrated with each other using adhesive. Thirdly, a heat-resistant fiberboard (for example, ``Fine Flex Softboard'' manufactured by Nippon Asbestos Co., Ltd.) is provided as a backup material on the top of the blanket to prevent the internal combustion gas from rising. The fourth reason is that the passage is prevented, and the fourth is the provision of heat-resistant fiberboard.
The main feature is that the rod support hardware is fixed to the hanging tool through a sacrificial board that passes through the heat-resistant fiberboard.

Passing through this heat-resistant fiberboard 2, sacrificial boards 3, 3... are arranged at intervals in the longitudinal direction of the furnace lid and adjacent to it in the width direction, the upper part of which is fixed to a hanging tool, and the lower part of which is heat-resistant. It extends through the fiberboard 2. At the bottom of the heat-resistant fiberboard 2, a large number of blankets 4, 4, . Reference numeral 5 denotes a plate-shaped rod support member, to which a stack rod 6 is fixed perpendicularly. Further, the rod support member 5 is formed with a rod insertion hole 5a having a hole core parallel to the stack rod 6. Regarding the longitudinal direction of the furnace lid, the rear stack rod 6 is inserted into the rod insertion hole 5a of the front rod support member 5. The rod support member 5 has the function of connecting the stack rods 6, and also has the function of a seat plate for compressing a plurality of layers of blankets 4, for example, 16 blankets, as will be described later. The rod support member 5 is fixed to the extending portion 3a of the sacrificial plate 3 by welding or the like at the upper part of the blanket 4 in a compressed state. Thus, the blankets 4, 4, . . . are suspended by the stack rods 6, 6, .

4... are brought in and pressed together with the adhesive 7 against the existing blanket 4 using the rod support member 5 having the stacked rod 6 as a seat. As a result, the newly installed blankets 4, 4, . be done. At this time, the rod support member 5 passes through the extending portion 3a of the sacrificial plate 3 from below as it is compressed, is applied to the rear surface of the sacrificial plate 3, and is fixed by welding at the extending portion 3a. After that, such construction is carried out one after another, and blankets are placed over the entire length of the furnace lid. Here, the blanket is compressed with a margin of about 300 mm from the furnace width in the furnace lid width direction, and the blanket is compressed at a compression rate of 25 to 35%, usually about 30%, in the furnace lid longitudinal direction. Compress and place. In addition, since each blanket is attached with adhesive, shrinkage in the thickness direction of the blanket can be prevented from occurring at the blanket interface, and even if shrinkage occurs, it only occurs within the tangles of the blanket fibers. Therefore, gas loss can be reliably prevented. Even if a crack should occur in the blanket, a heat-resistant fiberboard is provided on top of the blanket, which functions as a back-up material and prevents internal combustion gas from permeating to the iron shell. In addition, since the rod support member 5 integrated with the stack rod 6 is provided in series for compressing and piercing the blanket 4, the construction is extremely simple. Moreover, in the present invention, since the heat-resistant fiberboard 2 is arranged on the upper part of the blanket 4, the rod support member 5 is attached to the hanging tool 1 in some way.
However, since the hanging fixture 1 is provided with a sacrificial plate 3 that penetrates the heat-resistant fiberboard 2, the rod support member 5 can be easily fixed to the hanging fixture 5 via this sacrificial plate 3. It is suitable because it can be fixed in place.

Furthermore, by applying a fire-resistant surface protection material 8 to the lower surface of the blanket 4, it is possible to prevent internal combustion gas from entering the blanket 4, and to prevent the lower surface of the blanket 4 from being eroded.
