本考案は、コイル状に巻かれた鋼帯等の金属の
被熱処理材を、環状の回転炉床上に載置して連続
的に熱処理を行う回転式熱処理炉の炉床の構造に
関するものである。[Detailed description of the invention] This invention is a rotary heat treatment furnace in which a metal material to be heat treated, such as a coiled steel strip, is placed on an annular rotary hearth and heat treated continuously. It concerns the structure of the floor.
第１図は従来の回転式熱処理炉の断面平面図、
第２図は第１図のＡ−Ａ矢視図である。 Figure 1 is a cross-sectional plan view of a conventional rotary heat treatment furnace.
FIG. 2 is a view taken along the line A--A in FIG. 1.
従来の環状式の回転式炉床は、第１図、第２図
に示すように、耐火断熱材１ａとそれを支持する
フレーム１ｂとからなる一体の環状炉床１を、一
体の環状台車２の上に載設固着した一体構造に形
成されているのが一般的である。 As shown in FIGS. 1 and 2, a conventional annular rotary hearth has an integral annular hearth 1 consisting of a refractory heat insulating material 1a and a frame 1b that supports it, and an integral annular truck 2. It is generally formed into an integral structure that is mounted and fixed on top of.

ある。 1 and 2, 1 is an annular hearth, 2 is an annular truck, 3 is a side wall, 4 to 8 represent functional divisions of each part of the rotary heat treatment furnace, 4 is a material loading/unloading zone,
5 is a heating zone, 6 is a soaking zone, 7 is an in-furnace slow cooling zone, and 8 is an outside cooling zone. Further, 9 is a water seal, and 10 and 11 are gaps between the furnace side wall and the annular hearth 1.
従来の回転式熱処理炉は以下に述べる問題があ
つた。 Conventional rotary heat treatment furnaces have had the following problems.
１ 炉床の耐火断熱材を新設する場合または全炉
床を修理する場合、炉床が炉外にある部分すな
わち第１図の処理材料の載荷脱荷帯４の部分と
炉外冷却帯８の部分でしか築炉工事ができない
ため、作業能率が極めて悪い。1. When installing a new fireproof insulation material for the hearth or repairing the whole hearth, the parts of the hearth outside the hearth, that is, the parts of the loading/unloading zone 4 for processing materials in Figure 1 and the outside cooling zone 8. Work efficiency is extremely low because furnace construction work can only be done in sections.
２ 炉床１の部分修理をする場合、損傷が軽度の
場合は修理する部分が炉外にある時に、被熱処
理材の品質上および生産上許される範囲で、炉
床の回転を一時的に停止するかまたは炉床の回
転速度を落して短時間に修理を行うことは可能
ではあるが、著しく制約を受け本格的な作業が
困難である。部分的でも損傷が大きい場合は、
上記方法では作業時間がとれないため炉を休止
せざるを得ない。2. When partially repairing the hearth 1, if the damage is minor, the rotation of the hearth should be temporarily stopped while the part to be repaired is outside the furnace, to the extent permitted by the quality of the material to be heat treated and production. Although it is possible to carry out repairs in a short time by reducing the rotational speed of the hearth, it is severely restricted and makes full-scale work difficult. If the damage is large, even if only partially,
The above method does not allow enough time for work, so the furnace has to be shut down.
３ 環状炉床１および環状台車２が熱変形すると
（一般的には楕円状に変形する）、炉体側面３と
の隙間１０が大きくなり熱損失が大きくなる。3. When the annular hearth 1 and the annular carriage 2 are thermally deformed (generally deformed into an elliptical shape), the gap 10 between them and the side surface 3 of the furnace body increases, resulting in increased heat loss.
４ 熱変形がさらに大きくなると、炉体側面３と
炉床１とが隙間部１１で接触し炉が損傷する。4. If the thermal deformation becomes even larger, the furnace side surface 3 and the hearth 1 will come into contact with each other at the gap 11, causing damage to the furnace.
本考案は従来避けられなかつた上記の問題を解
決するものである。 The present invention solves the above-mentioned problems that could not be avoided in the past.
以下本考案の実施例の図面に基づいて説明す
る。第３図は本考案の一実施例の環状炉床平面図
であり、第４図は第３図のＢ−Ｂ矢視断面図であ
る。 Embodiments of the present invention will be described below based on the drawings. FIG. 3 is a plan view of an annular hearth according to an embodiment of the present invention, and FIG. 4 is a sectional view taken along the line B--B in FIG. 3.
本考案の炉床は第３図、第４図に示すように、
回転する環状台車２の上に環状炉床を円周方向に
多数に分割した炉床ユニツト１２を載設した二重
構造になつており、炉床ユニツト１２は、前記環
状台車２上に着脱自在にかつ半径方向載設位置調
整自在に固着されている。 The hearth of the present invention is shown in Figures 3 and 4,
It has a double structure in which a hearth unit 12 in which an annular hearth is divided into many parts in the circumferential direction is mounted on a rotating annular carriage 2, and the hearth unit 12 is detachably attached to the annular carriage 2. It is fixed in such a way that the mounting position can be freely adjusted in the radial direction.
第３図の実施例では環状炉床の円周を24等分し
た例であるが、環状炉床の分割数は炉床ユニツト
１２のハンドリングの面と、環状台車２の熱変形
の面を勘案して決定され、経験的に炉床ユニツト
１２は環状炉床の円周方向の長さを４〜５ｍとす
るのが適当である。 In the embodiment shown in FIG. 3, the circumference of the annular hearth is divided into 24 equal parts, but the number of divisions of the annular hearth is determined in consideration of handling of the hearth unit 12 and thermal deformation of the annular carriage 2. Based on experience, it is appropriate that the length of the annular hearth in the circumferential direction of the hearth unit 12 be 4 to 5 m.

脱着することができる。 FIG. 5 is a partially enlarged view of the hearth in FIG. 4 and is an explanatory diagram of its handling. The mechanism for adjusting the hearth unit 12 in the radial direction of the annular truck 2 is, for example, by providing left and right adjusting bolts 13 on the frame 12a of the hearth unit 12 and adjusting these. This is done by moving relatively. Further, the hearth unit 12 and the annular carriage 2 are configured to be fixed with fixing bolts 14 via a bracket 15, and by removing the bracket 15, the hearth unit 12 can be easily attached and detached from the annular carriage 2. .
