For example, in a steel heating furnace, in addition to directly heating the steel material through convection heat transfer of high-temperature gas in the furnace, the steel material is also heated by radiation heat transfer from the furnace inner wall surface heated by the high-temperature gas. However, since radiant heating from the wall surface has a high heat transfer efficiency to the heated object and can provide effective heating, efforts are being made to increase the area of the radiant wall in the furnace. As an example of this, for example, JP-A-60
-The radiant panel shown in Publication No. 17686 has a bottom plate attached at both ends to the lower end of a hanging rod suspended from the ceiling of the furnace at an appropriate interval, and a ventilated flat plate is placed in multiple stages on top of the bottom plate. The ventilated plates are stacked up to form a radiant surface by passing the high-temperature gas inside the furnace through these ventilated plates. is inserted into the groove on the bottom plate having a concave cross section, and then a slip prevention member having an H-shaped cross section and having approximately the same length and width as the bottom plate is passed through the hanging rod from above to cover the upper edge of the breathable plate.
Insert the lower edge of the second tier of breathable plates onto this slip-preventing member, and then stack up the breathable plates one after another by covering the upper edge of this breathable plate with another slip-preventing member in the same manner as described above. It was hot. Therefore, this structure has the following problems.
(イ) 通気性板を保持する底板はセラミツク等の高
耐熱材料にて成形しなければならないがその断
面形状が非対称であるので焼成時に反りが発生
しやすく焼成後の矯正や機械加工が必要になり
製作費が高く。また、使用時にも少しの温度差
で反りが出やすく通気性板に負荷をかけたり、
逆に外れたりしやすい。また反りを抑えようと
して溝を浅くすると外れやすい。(b) The bottom plate that holds the breathable plate must be made of a highly heat-resistant material such as ceramic, but because its cross-sectional shape is asymmetrical, it tends to warp during firing, requiring straightening or machining after firing. The production cost is high. In addition, even when used, even a slight temperature difference can easily cause warping, putting stress on the breathable board.
On the other hand, it can easily come off. Also, if you make the groove shallow to prevent warping, it will easily come off.
(ロ) 断面Ｈ形のずれ防止部材はセラミツクにて成
形する場合製作上５〜10mmの厚さが必要である
のでその厚さ分は少なくとも通気性板の通気面
積ひいては輻射壁面積が減少せざる得ない。(b) If the anti-slip member with an H-shaped cross section is molded from ceramic, it needs to be 5 to 10 mm thick, so at least that thickness will reduce the ventilation area of the breathable plate and the area of the radiation wall. I don't get it.
(ハ) 底板が熱膨張により長手方向に伸びると吊下
棒に曲げ応力が掛かりこれを変形させ損壊させ
るおそれがある。(c) If the bottom plate stretches in the longitudinal direction due to thermal expansion, bending stress will be applied to the suspension rod, which may deform and damage it.
(ニ) 下段にある通気性板が使用途中で破損した場
合にこれを交換しようとするとその上の通気性
板およびずれ防止部材を全部上に外していかな
ければその通気性板の取替えができず保守作業
が非常に面倒で狭い炉内でこれを行うことは困
難であつた。(d) If the breathable plate on the lower level is damaged during use and you try to replace it, you will not be able to replace the breathable plate unless you remove all the upper breathable plates and the anti-slip member upwards. However, the maintenance work was extremely troublesome and difficult to perform in a narrow furnace.

該仕切壁を吊下できる。 According to the suspended furnace partition wall configured in this way, the lower end surfaces of each vertical rod 4, 4, 4 and the horizontal rod 5
Since the head rod pin 12 is loosely inserted so that the horizontal rods 5 butt against the sides and have freedom of movement, even if the horizontal rod 5 thermally expands due to the high temperature gas in the furnace and extends in its length direction, it will remain vertical. Since the rod 4 is not bent, the vertical rod 4 will not be deformed or broken due to this. Also, such vertical rods 4, 4, 4
Since the head rod pin 12 is inserted vertically from below in the structure in which the vertical rod 4 and the horizontal rod 5 are butted against each other, it is assumed that the side surface of the vertical rod 4 and the end surface of the horizontal rod 5 are butted and the headed rod pin is inserted into the vertical rod. In the configuration in which the head rod pin is inserted sideways into the horizontal rod 5 from the side surface of the head rod 4, shearing load is applied to the headed rod pin, causing it to break, but there is no such problem. Furthermore, since each wall plate 6, 6... is simply supported by holding plates 17, 17 from both sides, each wall plate 6, 6...
6 can freely thermally expand or contract, and no excessive thermal stress is applied to each of the wall plates 6, 6..., so that the wall plates 6 will not be damaged thereby. Furthermore, since each wall plate 6, 6... is arranged in the same plane surrounded by each vertical rod 4, 4, 4 and horizontal rod 5, an unbalanced load is generated to the front or rear side, causing the vertical rod 4 to bend. No stress is applied, and therefore, the problem of breakage of the vertical rod 4 does not occur at this point either. Also, when wall plate 6 is damaged, in order to replace it, hold the wall plate immediately above the damaged wall plate for a short time, destroy and remove the damaged wall plate, and then replace the upper wall plate. If you use it by lowering it down and inserting a new wall board into the empty space at the top, it is easy to just move the wall board in the damaged row. In addition, by adjusting the protrusion length of the hanging rod 7 into the furnace by the bearing member 9, the vertical rods 4, 4, 4
Since the vertical rods 4, 4, 4 move up and down, the elongation due to thermal expansion can be accommodated, and the partition wall can be suspended in the furnace without any gaps around it.

In this way, the hanging furnace partition wall of the present invention is
Since the vertical rod and the horizontal rod are hollow rectangular rods with the same diameter and symmetrical cross sections, they can be easily molded from ceramic without warping, and manufacturing costs are low.
In addition, the horizontal rod is fixed to the lower end of the vertical rod by loosely inserting a headed rod pin, so even if the horizontal rod expands thermally, unnecessary stress will not be applied to the vertical rod, preventing problems such as breakage and bending. There is little risk of occurrence. Further, the hanging rod supported by the bearing member outside the furnace allows the height of the partition wall inside the furnace to be easily adjusted, so that elongation due to thermal expansion can be easily coped with. Furthermore, since the wall plate is attached with only its both side edges partially covering the holding plate, a large area of the radiant wall can be obtained and thermal efficiency is improved. Furthermore, even if a wall board located in the lower row is damaged, it can be easily replaced by simply removing the damaged wall board, moving the row down, and inserting a new wall board in the top row, making maintenance easy. There are various advantages.
