本発明は、金属の圧延工程等に用いる保温用カバー部材
に関するものである。DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a heat-retaining cover member used in metal rolling processes and the like.
［従来の技術］
金属の圧延工程では、加熱炉により均一に再加熱された
鋼片が、搬送ロールにより移送され、表面に発生したス
ケールを除去した後、粗圧延され、幅合わせ等を行なっ
た後、必要厚みに圧延される。[Prior art] In the metal rolling process, a steel billet is uniformly reheated in a heating furnace, transported by conveyor rolls, scale generated on the surface is removed, and then roughly rolled to perform width adjustment, etc. After that, it is rolled to the required thickness.
この際、圧延ロールの進行方向前方では、圧延により、
薄くなっている為、進行速度は速いが、後方では相対的
に遅くなっている。At this time, in front of the rolling roll in the rolling direction, due to rolling,
Because it is thinner, it moves faster, but it is relatively slower at the rear.
圧延ロールにかける温度をできる限り一定にする為、所
謂デイレ−テーブルにはこの勘の放熱を防止する保温カ
バーがあれば好ましい。In order to keep the temperature applied to the rolling rolls as constant as possible, it is preferable that the so-called delay table has a heat insulating cover to prevent heat radiation.
従来、この圧延ロール手前の部分の保温断熱用のカバー
は、セラミックファイバーのブランケットを積層し、そ
れを枠構造を有した鉄骨に取りつけたものを使用してい
た。これは、セラミックの耐熱性とファイバーの断熱性
を利用したものである。Conventionally, the heat-insulating cover in front of the rolling rolls was made by laminating ceramic fiber blankets and attaching them to a steel frame with a frame structure. This takes advantage of the heat resistance of ceramics and the insulation properties of fibers.
また、このセラミックファイバーをステンレス鋼板によ
ってカバーしたものも使用されていた。Additionally, ceramic fibers covered with a stainless steel plate were also used.
［発明が解決しようとする課題］
しかしながら、通常の圧延工程では、粗圧延の手前でス
ケールをとる為、高圧水で所謂デスケーリングを行なう
。又、圧延装置にも、ロールの冷却の為大量の水を使用
する。このように、圧延ラインをカバーする為には、耐
熱と同時に耐水性も要求される。この為、このラインに
使用されるカバーは、より過酷な熱的状況におかれ、前
者の方法では、その水がかかりファイバー質が脱落し、
その部分の保温断熱効果が著しく落ちるという欠点があ
った。[Problems to be Solved by the Invention] However, in a normal rolling process, in order to remove scale before rough rolling, so-called descaling is performed using high-pressure water. Also, rolling equipment uses a large amount of water to cool the rolls. In this way, in order to cover the rolling line, water resistance is required as well as heat resistance. For this reason, the cover used for this line is exposed to harsher thermal conditions, and in the former method, the fibers are exposed to water and fall off.
There was a drawback that the heat retention and insulation effect of that part was significantly reduced.
また、ステンレス鋼板を貼ったものでは、ファイバー質
が脱落する欠点はないものの、熱膨張が大きく、変形し
たり、外れて落下する危険性もある為、可使用期間が短
かかった。In addition, although stainless steel plates do not have the disadvantage of fibers falling off, they have a short shelf life because of their large thermal expansion and the risk of deformation or falling off.
そこで、本業界では、このような場所に使用するための
保温断熱カバーが要望されていた。Therefore, there has been a demand in the industry for a heat-retaining insulation cover for use in such places.
［課題を解決するための手段］
以上のような現状に鑑み、本発明者は鋭意研究の結果、
本発明カバーを完成したものであり、その特徴とすると
ころは、波板状の金属板に膨ＨＡ！鉛シートを接合した
点にある。[Means for Solving the Problems] In view of the above-mentioned current situation, the present inventor has conducted intensive research and has discovered the following.
The cover of the present invention has been completed, and its feature is that the corrugated metal plate has an expanded HA! It is located at the point where the lead sheets are joined.
ここで、金属板とは金属製の板であり、材質は特別限定
するものではないが、その耐熱性と価格の問題からステ
ンレス鋼が好適である。Here, the metal plate is a metal plate, and the material is not particularly limited, but stainless steel is preferable due to its heat resistance and cost.
ここで「ステンレス鋼ｊは、フェライト系、オーステナ
イト系、マルテン号イト系、二相系、析出硬化型ステン
レス鋼を指すものであり、代表的には５ＯＳ３０４Ｈ材
や５ＵＳ３０１Ｈ材であるが、中でも５ＵＳ３１０Ｓが
好適である。「鋼板」の厚さは、限定はしないが０．１
〜２．０ｍｍが良く、特に０．８〜１．２−一が好まし
い。これは、０．１ｍ−未満であると補強効果が生じず
、２．０ｍ−を越えると伸縮の吸収が困難にあるためで
ある。Here, "stainless steel" refers to ferritic, austenitic, martenite, duplex, and precipitation hardening stainless steels, typically 5OS304H and 5US301H, but among them 5US310S. Suitable.The thickness of the "steel plate" is not limited, but is 0.1
-2.0 mm is good, and especially 0.8-1.2-1 is preferable. This is because if it is less than 0.1 m, no reinforcing effect will occur, and if it exceeds 2.0 m, it will be difficult to absorb expansion and contraction.
波板状とは、所謂波型であり、スレートやトタン等に見
られる形状である。これは、伸縮によって破断したり、
組成変形しないようにするためである。The corrugated sheet shape is a so-called corrugated shape, and is a shape found in slate, galvanized iron, and the like. This may break due to expansion or contraction, or
This is to prevent compositional deformation.
「膨脹黒鉛」は、次のような製法によって得られるもの
である。"Expanded graphite" is obtained by the following manufacturing method.
天然黒鉛、熱分解黒鉛、キッシュ黒鉛等を、硫酸や硝酸
ナトリウム、過マンガン酸カリウムまたは臭素やハロゲ
ン化物で処理すると眉間化合物が得られる。この眉間化
合物は、黒鉛の層状構造の眉間に他の反応物質が侵入し
て炭素平面と結合を持ち、炭素の層状構造を維持したま
まの結晶化合物である。これを高温で処理することによ
って、眉間化合物がガスを発生し、それにより黒鉛眉間
は拡張される。通常炭素平面と直角の方向に１００〜２
００倍程度拡張する。この拡張された黒鉛が膨脹黒鉛で
ある。When natural graphite, pyrolytic graphite, quiche graphite, etc. are treated with sulfuric acid, sodium nitrate, potassium permanganate, bromine, or halides, glabellar compounds are obtained. This glabellar compound is a crystalline compound in which other reactants enter the glabella of the graphite layered structure and form bonds with carbon planes, maintaining the carbon layered structure. By treating it at high temperatures, the glabellar compound generates gas, thereby expanding the graphite glabella. Usually 100 to 2 in the direction perpendicular to the carbon plane
Expand by about 00 times. This expanded graphite is expanded graphite.
この膨脹黒鉛には、バインダーとして酢酸セルローズや
フェノール樹脂等の合成樹脂を混合しても良い。また、
酸化黒鉛を配合したものを用いても良い。結局、本発明
でいう膨脹黒鉛は、主剤として前記した膨脹黒鉛が含ま
れていれば良く、その他のものを混合することは自由で
ある。This expanded graphite may be mixed with a synthetic resin such as cellulose acetate or phenol resin as a binder. Also,
A material containing graphite oxide may also be used. After all, the expanded graphite referred to in the present invention only needs to contain the above-mentioned expanded graphite as a main ingredient, and other materials may be mixed at will.
膨脹黒鉛の上記した構造上の理由から、シートの厚み方
向には大きな断熱効果を有し、平面方向には比較的大き
な熱伝導を示すという性質を有している。Due to the above-mentioned structure of expanded graphite, it has the property of having a large heat insulating effect in the thickness direction of the sheet and relatively large heat conduction in the planar direction.
本発明は、この性質を応用したものであり、厚み方向即
ち、カバーの上方に対しては、断熱効果として働き、水
平方向では、適度な熱伝導率により、ステンレス板に均
熱効果（局部的な高温を発生させない）を与え、歪の発
生を抑える役割を果たすものである。The present invention applies this property, and works as a heat insulating effect in the thickness direction, that is, above the cover, and in the horizontal direction, has a heat-uniforming effect (locally It plays the role of suppressing the generation of distortion by providing a high temperature (not generating high temperatures) and suppressing the generation of distortion.
膨脹黒鉛シートの厚みは、０．２〜２．（１＋＋ｍ程度
が好適である。これも、上記同様０．２ｍｍ以下では断
熱効果が小さくなり、２．０ｍｍ以上では伸縮に追従し
難いためである。The thickness of the expanded graphite sheet is 0.2 to 2. (Approximately 1++ m is preferable. This is also because, as above, if the thickness is 0.2 mm or less, the heat insulating effect will be small, and if it is 2.0 mm or more, it will be difficult to follow expansion and contraction.
波状板と膨脹黒鉛シートとの接合は、接着剤で接着する
のが簡単である。接着剤としては、具体的にその種類を
限定するものではないが、汎用性及び信頼性の面から熱
硬化性接着剤であるフェノール樹脂、エポキシ樹脂、イ
ミド樹脂などが好適である。The corrugated plate and the expanded graphite sheet can be easily joined with adhesive. Although the type of adhesive is not specifically limited, thermosetting adhesives such as phenol resin, epoxy resin, and imide resin are suitable from the viewpoint of versatility and reliability.

がフェルトより断熱効果が高く、よりコンパクトな装置
にできる。又、水の飛散に対しても膨潤流出は少ない。Another example of the present invention is to have a ceramic fiber sheet affixed to the corrugated composite. The ceramic fiber sheet may be of any type, such as a laminated sheet of ceramic fiber woven cloth or a thick blanket-like sheet. Preferably, the use of ceramic cloth has a better heat insulating effect than felt and allows for a more compact device. Also, there is little swelling and outflow when water is scattered.
このセラミック繊維製シートは、膨脹黒鉛等と同様に、
波型に沿わせて固着しても、比較的平に固定してもよい

本発明波型保温カバーは、一種の材料であり、圧延工程
等の通路保温に用いる場合、その部分として使用するも
ので、どのような形状に加工してもよい。The corrugated heat-insulating cover of the present invention is a type of material, and when used for heat-insulating passages in rolling processes, etc., it is used as a part thereof, and may be processed into any shape.
