れる熱処理炉の炉殻構造に関する。[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a furnace shell structure of a heat treatment furnace assembled by connecting a plurality of panels.
従来、熱処理炉、例えば薄板連続熱処理炉で
は、その炉殻は第１図に示されるように、支注
１、バツクステ−２および側面平板３とから構成
されていた。この炉殻構造は、前記各部材を夫々
個別に受け入れて、熱処理炉据付現場にて組み立
てを行うもので、障子張構造と呼ばれている。
Conventionally, in a heat treatment furnace, for example, a continuous thin plate heat treatment furnace, the furnace shell was composed of a support 1, a backstay 2, and a side plate 3, as shown in FIG. This furnace shell structure receives each of the above-mentioned members individually and is assembled at the heat treatment furnace installation site, and is called a shoji-paned structure.
上記障子張構造の炉殻は、据付現場での溶接量
が極めて多く、またその溶接方向も多様であつ
た。このため、溶接時の炉殻歪量が大きく、品質
寸法精度確保が困難な上、シ−ル溶接部に欠陥が
出やすく、ガスタイト性が劣るという欠点があつ
た。また、溶接に手間がかかることから製作に長
時間を要し、さらに手直の工数も大となるため、
生産性が悪いという欠点があつた。 The furnace shell of the above-mentioned shoji clad structure required an extremely large amount of welding at the installation site, and the welding directions were also diverse. For this reason, the amount of distortion in the furnace shell during welding is large, making it difficult to ensure quality and dimensional accuracy, and the seal welds are prone to defects, resulting in poor gas tightness. In addition, since welding is labor intensive, it takes a long time to manufacture, and the number of rework is also large.
The drawback was poor productivity.
上記障子張構造の欠点を解決するものとして、
予じめ工場で製作された複数枚のパネルを据付現

造である。 As a solution to the drawbacks of the above-mentioned shoji clad structure,
A furnace shell structure is known in which a furnace shell is formed by connecting and assembling a plurality of panels manufactured in advance at a factory at an installation site. As shown in FIG. 2, this furnace shell structure includes a plurality of panels 6 each consisting of a flat plate 4 and a backstay 5 welded to the flat plate. The structure is welded together and assembled into the furnace shell.

テ−５の全てが、シ−ル溶接により接合されるた
め、工場での製作時に、既に比較的大きな歪がパ
ネルに生じている。 However, in the above-mentioned furnace shell structure, in order to ensure gas sealing properties when assembled as a furnace shell, the backstay 5 is joined to the flat plate 4 as shown in FIG. 2B. It is necessary to use welding 7.
For this reason, all of the backstays 5 arranged around the four circumferences of the panel are joined by seal welding, except for the intermediate backstays 5', which are arranged as necessary. A relatively large distortion has occurred in the panel.
前記溶接歪等によるパネルの製作誤差を吸収

ツクステ−とスペ−サはシ−ル溶接により接合さ
れる。 In order to absorb panel manufacturing errors caused by welding distortion, etc., and to obtain a furnace shell with good precision, spacers 8 are placed between adjacent panels 6 over the entire area during assembly at the installation site. . Therefore, the backstays of adjacent panels are welded together via the spacer, and for the same reason as mentioned above, the backstay and spacer are joined by seal welding.
このように、従来のパネル組立による炉殻構造

り、この作業に長時間を要することから、組立時
間に関しては、未だに問題を残している。 In this way, in the conventional furnace shell structure based on panel assembly, all level adjustment between panels is done using spacers, which requires a large number of different types of spacers, and setting the shape of the spacers is complicated. Moreover, when assembling, it is necessary to process and adjust the actual model, and this work takes a long time, so there is still a problem with the assembly time.
なお、前記第２図Ｂ中、左方は炉外側、右方は
炉内側である。 In addition, in FIG. 2B, the left side is the outside of the furnace, and the right side is the inside of the furnace.
本考案は上記事実を考慮し、パネル間のレベル

を目的とする。
In consideration of the above facts, the present invention aims to provide a furnace shell structure that enables level adjustment between panels without using spacers and achieves a significant reduction in assembly time.

In the furnace shell structure of the heat treatment furnace according to the present invention, joints are formed in all or one panel by bending the ends of the flat plates in a stepped manner, and when assembled, adjacent panels are , by overlapping and welding the ends of the flat plates on which no joints are formed and the joints, and connecting the backstays through battens, the level between the panels can be adjusted at the overlapped parts. This makes it possible to significantly shorten the assembly time.

合せで実施可能である。 Regarding the joints formed at the ends of the flat plates of the panels, for example, as shown in Figure 3, if we look only at the vertical direction of the furnace shell, as shown in Figure A, all the panels (the lowest panel) ) are manufactured to have the same shape, and when assembled, the joints of all panels are positioned downward and connected, or as shown in Figure B, the joints are formed on both ends of the panel. It is possible to manufacture two types of panels, one without the other, and connect them by alternately positioning them during assembly, or in various other combinations.

The back surface of the left end of the panel 6B overlaps with the front surface of the panel 6B, and the overlapping portion is joined by welding. To adjust the level of panel 6B relative to panel 6A, move the left end of panel 6B to the joint of panel 6A.
It can be adjusted as desired by sliding up and down and left and right. As shown in FIG. 4B, the overlapping portions are welded by intermittent welding 7' from the back side and by seal welding 7 from the front side.

The back surface of the upper end of the panel 6C overlaps the surface of the joint part 4' of the lower end of the panel 6C.
After adjusting the level with respect to A, join the overlapping part in the same manner as above. Continuing, as shown in FIG. 5D,
The back surface of the upper end portion and the back surface of the left end portion of the panel 6D are superimposed on the surface of the joint portion 4′ at the lower end portion of the panel 6B and the surface of the joint portion 4′ at the right end portion of the panel 6C, respectively. After adjusting the levels of panels 6B and 6C, the overlapping portions are joined in the same manner as described above. Finally, a small piece of spacer 8 is inserted into the gap created between the joints of adjacent panels, and the panels are joined by seal welding. Incidentally, as shown in FIG. 5, the spacer may be inserted and joined each time the panels are overlapped.

９で接続されている。 As shown in FIG. 4, backstays 5 and intermediate backstays 5' of adjacent panels are connected through battens 9. The battens 9 are attached to the adjacent backstacks 5 (or intermediate backstacks).
The flange portions and the web portions of 5') are arranged so as to be connected to each other, and are fixed by bolting, welding, or a combination of both. As shown in FIG. 4B, the web portions of the backstays 5 that are vertically adjacent to each other are connected by a batten 9 via a bracket 10 that is welded and fixed to the web.
以上説明した通り、本実施例では、バツクステ

めて小さく、また溶接作業に要する時間も大巾に
減少する。 As explained above, in this example, the backstay is not located at the panel connection point to join the backstay to the flat plate, so there is no need for seal welding, and intermittent welding is possible. Distortion is extremely small, and the time required for welding work is also greatly reduced.
また隣接するパネル同志は、平板同志が直接接
続されるために、パネル間のシ−ル溶接は１条で
良く（従来は２条）、炉殻の歪発生が大巾に減少
し、据付現場での溶接作業時間も大巾に減少す
る。 In addition, since adjacent panels are directly connected to each other by flat plates, only one seal weld is required between the panels (previously two seal welds were required), greatly reducing the occurrence of distortion in the furnace shell, and allowing installation at the installation site. Welding work time is also significantly reduced.

く、必要とするスペ−サの数も減少する。 Furthermore, since the level of each panel can be adjusted without using spacers, the panels can be connected without waiting for the spacers to be assembled, which improves setup and greatly reduces work time. Further, since the spacer inserted between each panel is a small piece, the time required for processing can be shortened. In this example, 4
Only two spacers can be placed between the panels, reducing the number of spacers required.
またさらに、バツクステ−を強度部材としての

As described above, the furnace shell structure of the heat treatment furnace according to the present invention is constructed by connecting panels in which the ends of flat plates are bent in steps to form joints, so when connecting the panels, the level between the panels is Adjustment is possible without using spacers, and the assembly time at the sliding site is greatly shortened.
