(57) [Summary] [Structure] The rod of the high temperature conveyor consisting of the conveyor chain and the rod connecting the conveyor chain is made of carbon fiber reinforced carbon,
This is coated with a carburization-resistant and oxidation-resistant metal such as a Cr-Ni alloy. [Effect] Since the carbon fiber reinforced carbon of the rod is coated with an oxidation resistant metal, its excellent high tensile properties are not impaired even in a high humidity acidic furnace atmosphere, and the coating metal is carburized resistant. Therefore, the coated carbon does not impair its physical properties. Therefore, the conveyor using this rod has a long durable life without being deformed even in an atmosphere of a high temperature acidic furnace.
Description
【０００１】[0001]
本考案は、金属性のコンベアチェンを連結するためのロッドに炭素繊維強化炭 素（ＣＦＲＣ）を用い、耐浸炭性，耐酸化性金属でこの炭素繊維強化炭素製のロ ッドを被覆して炉内雰囲気による酸化から保護すると共に、該被覆金属の炭素繊 維強化炭素による浸炭をも防ぐようにした高温連続炉用コンベアベルトに関する ものである。 In the present invention, carbon fiber reinforced carbon (CFRC) is used for a rod for connecting a metal conveyor chain, and the carbon fiber reinforced carbon rod is coated with a carburizing and oxidation resistant metal. The present invention relates to a conveyor belt for a high-temperature continuous furnace, which is protected from oxidation by the atmosphere in the furnace and is also prevented from carburizing the coating metal with carbon fiber-reinforced carbon.

高温炉で金属製品等を高温処理するとき、この金属製品を炉内で搬送するため に無端でチェン状に連ながるコンベアベルトが用いられる。このコンベアチェン は多数のチェン又はスパイラルからなるものであるが、これらを連結するチェン ロッドの材料には耐熱鋼線が使われているが、１０００〜１２００℃の雰囲気下 ではその曲げ強度は最高でも３ｋｇ／ｍｍ２と弱く、短時間でロッドが変形し、 ロッドとチェン又はスパイラルの結合部に平均した剪断力が働らかなくなり、局 部的に大きな剪断力が加わり、この結果チェン又はスパイラルが切断したり、ベ ルトの蛇行が起こり、コンベアが使用不能となる。When a metal product is processed at a high temperature in a high temperature furnace, an endless chain-like conveyor belt is used to convey the metal product in the furnace. This conveyor chain consists of many chains or spirals, and heat-resistant steel wire is used for the material of the chain rod that connects these chains, but its bending strength is the highest in the atmosphere of 1000 to 1200 ° C. It is weak at 3 kg / mm 2 , the rod deforms in a short time, the average shearing force does not work at the joint between the rod and the chain or spiral, and a large shearing force is locally applied, resulting in the chain or spiraling. The conveyor becomes unusable due to cutting and belt meandering.
【０００３】 炭素繊維強化炭素を用いたコンベアベルトは、実開昭６２−９８６１４号，実 開平１−１２１０１０号，特開平１−２０７４６４号公報に記載されている。炭 素繊維強化炭素は２５００℃までは常温よりその強度が増加する傾向にあるが、 炭素と反応を起こす酸化性の雰囲気下での使用には不都合がある。Conveyor belts using carbon fiber reinforced carbon are described in Japanese Utility Model Publication No. 62-98614, Japanese Utility Model Publication No. 1-121010, and Japanese Patent Application Laid-Open No. 1-207464. Carbon fiber reinforced carbon tends to increase its strength from room temperature up to 2500 ° C, but it is inconvenient to use it in an oxidizing atmosphere where it reacts with carbon.
【０００４】[0004]
炉中をコンベアベルトが循環通過するとき、ベルトの進行方向に対して横方向 に組込まれたロッドに特に高い張力、即ちロッドに対してほぼ直角な剪断力か働 くので、ロッドのこの部分の抗張力、即ちロッドの長手方向に対してほぼ直角な 剪断耐力がロッドに特に保証されなければならない。 As the conveyor belt circulates through the furnace, a particularly high tension, i.e., a shear force approximately perpendicular to the rod, acts on the rod incorporated transversely to the direction of travel of the belt, so that this part of the rod is The tensile strength, that is to say the shear strength approximately perpendicular to the longitudinal direction of the rod, must be ensured for the rod.
【０００５】 そして、ロッドにこのような剪断耐力が乏しくてその変形が大きくなれば、コ ンベアベルト全体が蛇行することになり、正常な炉の運転ができなくなる。If the rod has such poor shear resistance and its deformation becomes large, the entire conveyor belt meanders, and normal furnace operation cannot be performed.
【０００６】 そこで、ロッドに特に高い抗張力を与え、コンベアベルトが酸化性雰囲気化で も長時間の使用に耐え得るようにすることが望まれる。Therefore, it is desired to give particularly high tensile strength to the rod so that the conveyor belt can withstand long-term use even in an oxidizing atmosphere.

本考案では、コンベアベルトの構成部品であるコンベアチェンを連結するロッ ドの外周を円筒状で耐浸炭性，耐酸化性の金属として、芯に炭素繊維強化炭素を その繊維方向が円筒の長手方向に整列するようにしたものである。以下、本考案 の実施例を図により説明する。 In the present invention, the outer circumference of the rod that connects the conveyor chains, which are the components of the conveyor belt, is made of a cylindrical metal having carburization resistance and oxidation resistance, and carbon fiber reinforced carbon is used as the core and the fiber direction is the longitudinal direction of the cylinder. It is arranged to be aligned. An embodiment of the present invention will be described below with reference to the drawings.

この実施例になるコンベアの外観は、バランス型といわれるメッシュベルトの 一種であり、通常高温用として耐熱鋼線が使用されている。図１に示されるスパ イラル状コンベアチェン２は従来型のφ３２ｍｍの耐熱鋼線（ＳＵＳ３１０）を 使い、コンベアの進行方向（図１中で矢符で示される）と直交するように伸展す る多数のロッド１は図２に図示される通り外周に外径５ｍｍ，内径４．４ｍｍの パイプ状の耐浸炭性，耐酸化性金属（ＳＵＳ３１０）を使用し、パイプの片方の 端末に直径４．２ｍｍ，長さ３ｍｍ（ＳＵＳ３１０）のチップ１″をパイプ内に 入れて溶接して封じ、次に反対側よりパイプ内に直径４．２ｍｍの炭素繊維強化 炭素棒１′を図２のように入れ、反対側の端末にも直径４．２ｍｍで長さ３ｍｍ のチップ１″を入れ、真空中で溶接して封じたものである。図１の如くロッド１ とスパイラル２を組み上げ、ロッド１とスパイラル端末２′を溶接する。 The appearance of the conveyor according to this embodiment is a kind of mesh belt called a balanced type, and heat resistant steel wire is usually used for high temperature. The spiral conveyor chain 2 shown in FIG. 1 uses a conventional φ32 mm heat-resistant steel wire (SUS310) and is extended to extend in a direction orthogonal to the traveling direction of the conveyor (indicated by an arrow in FIG. 1). As shown in Fig. 2, the rod 1 uses a pipe-shaped carburizing and oxidation resistant metal (SUS310) with an outer diameter of 5 mm and an inner diameter of 4.4 mm, and a diameter of 4.2 mm at one end of the pipe. , 3mm length (SUS310) tip 1 "is put into the pipe and welded and sealed, then put 4.2mm diameter carbon fiber reinforced carbon rod 1'into the pipe from the opposite side as shown in FIG. A tip 1 ″ having a diameter of 4.2 mm and a length of 3 mm was also put in the end on the opposite side, which was welded and sealed in a vacuum. As shown in FIG. 1, the rod 1 and the spiral 2 are assembled, and the rod 1 and the spiral end 2'are welded.
【０００９】 このコンベアベルトを用い、炉温１１２０℃，雰囲気として発熱型変成ガス（ 組成ＣＯ：８％，ＣＯ２：８．５％，Ｈ２：８．２％，Ｈ２Ｏ：０．８６％，Ｎ２ ：７４．４％）を用いて、綱の銅ろう付けを行なった。Using this conveyor belt, the furnace temperature is 1120 ° C., and the atmosphere is an exothermic shift gas (composition CO: 8%, CO 2 : 8.5%, H 2 : 8.2%, H 2 O: 0.86). %, N 2 : 74.4%) was used to braze the steel.
【００１０】 その結果、ロッド１の曲りはなく、寿命は該ロッド１が耐熱性鋼線のみによる 場合の２倍の寿命を得た。As a result, the rod 1 was not bent, and the life was twice as long as when the rod 1 was made of only the heat resistant steel wire.
【００１１】[0011]
本考案によれば、ロッド１の高張力は炭素繊維強化炭素１′により保証され、 この炭素繊維強化炭素は耐酸性金属１′によって被覆されているので、酸性雰囲 気下でも劣化するようなことがなく、また耐酸性金属は耐浸炭性でもあるので炭 素繊維強化炭素によって浸炭されて劣力することもない。従って、本考案になる ロッドは全体として耐酸性と耐浸炭性で高張力を有し、長期の使用寿命を有する 効果がある。 According to the present invention, the high tension of the rod 1 is guaranteed by the carbon fiber reinforced carbon 1 ', and since the carbon fiber reinforced carbon is covered with the acid resistant metal 1', it is likely to deteriorate even in an acidic atmosphere. Moreover, since the acid-resistant metal is also carburizing-resistant, it is not carburized by the carbon fiber reinforced carbon to be inferior. Therefore, the rod according to the present invention has an effect of having long-term service life, having high resistance to acid and carburization as a whole.
