(産業上の利用分野)
本発明は、高耐食性ロール、特に電気めっき槽設備内で
過酷な条件で使用される高耐食性ロールおよびその製造
法に関する。かかる高耐食性ロールは、主に電気めっき
用、ある腎)は溶融浸漬めっき用のジンクロール、ター
ンロール等に用いられる。DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a highly corrosion resistant roll, particularly a highly corrosion resistant roll used under harsh conditions in electroplating tank equipment, and a method for manufacturing the same. Such highly corrosion resistant rolls are mainly used for electroplating, and some are used as zinc rolls, turn rolls, etc. for hot-dip plating.
(従来の技術)
従来、耐食性を向上させるため、ロールはステンレス、
高合金等の高耐食性金属を用いてきた。(Conventional technology) Conventionally, to improve corrosion resistance, rolls were made of stainless steel,
Highly corrosion resistant metals such as high alloys have been used.
しかし長期にわたり使用するとロール表面が腐食され凹
凸が激しくなってストリップに疵を生しさせる問題があ
った。However, when used for a long period of time, the roll surface corrodes and becomes extremely uneven, resulting in the formation of flaws in the strip.
このため、ロール表面にセラミックを溶射して更に耐食
性を高めたロールが使用されている。For this reason, rolls are used whose surfaces are thermally sprayed with ceramic to further improve corrosion resistance.
しかし、このようなセラミック溶射被膜は多孔性被膜で
あり、長期に使用していると、被膜の孔部分を通してロ
ール自身が腐食され、そのためにセラミック溶射被膜が
内側から剥離するという問題が生し、これもストリップ
に疵を生しさせる要因となった。However, such a ceramic sprayed coating is a porous coating, and when used for a long time, the roll itself corrodes through the pores of the coating, which causes the problem that the ceramic sprayed coating peels off from the inside. This also caused flaws in the strip.
(発明が解決しようとする諜8)
この多孔性被膜の孔を埋めるため、最近では、電子ビー
ム若しくはレーザービームをセラミック溶射被膜の表面
に照射し、セラミックを溶かして(再溶融)封孔する方
法や、有機剤を使用して封孔する方法等が用いられてい
る。(Spirit 8) In order to fill the pores in this porous coating, a method has recently been developed that irradiates the surface of the ceramic sprayed coating with an electron beam or laser beam to melt (re-melt) the ceramic and seal the pores. A method of sealing the pores using an organic agent is also used.
前者の封孔方法では、真空式または局部真空式で照射処
理が行われるが、装置本体のコストが高く、封孔処理コ
ストも当然高くなり、経済性の面で劣る。また、この方
法では表面のセラミックのみを溶融して封孔するが、そ
のときの真空度によって封孔処理結果にばらつきが生し
る。特に本発明が対象とするような大型ロールを処理す
る場合、高真空度を常に一定に確保することは極めて困
難であるため、めっき液に浸漬するジンクロールのよう
な過酷な環境で使用されるロールでは充分な耐食性が確
保できなかった。In the former method of sealing, the irradiation treatment is performed using a vacuum method or a local vacuum method, but the cost of the main body of the apparatus is high, and the cost of the sealing treatment is also naturally high, so it is inferior in terms of economic efficiency. Further, in this method, only the ceramic on the surface is melted to seal the hole, but the result of the sealing process varies depending on the degree of vacuum at that time. Especially when processing large rolls such as those targeted by the present invention, it is extremely difficult to always maintain a constant high degree of vacuum, so they are used in harsh environments such as zinc rolls immersed in plating solution. Sufficient corrosion resistance could not be ensured with rolls.
一方、後者の有機剤を使用する方法は、真空脱ガスを行
った後、S1樹脂のような有機剤溶液に浸漬させて、高
温乾燥させる方法である。On the other hand, the latter method of using an organic agent is a method of performing vacuum degassing, then immersing it in an organic agent solution such as S1 resin, and drying at a high temperature.
この方法で問題となるのは、脱ガス不充分のまま有機剤
溶液に浸漬させると、封孔が十分でなくなり、耐食性が
極端に劣ることである。また有機剤の種類によっても耐
食性が左右される。The problem with this method is that if the material is immersed in an organic solution with insufficient degassing, the pores will not be sealed sufficiently and the corrosion resistance will be extremely poor. Corrosion resistance is also influenced by the type of organic agent.
従って、本発明の目的は、例えば電気めっき用めっき液
のような厳しい腐食環境にも高耐食性を示すセラミック
溶射高耐食性ロールおよびその安価な製造法を提供する
ことである。Therefore, an object of the present invention is to provide a highly corrosion-resistant ceramic sprayed roll that exhibits high corrosion resistance even in a severe corrosive environment such as a plating solution for electroplating, and an inexpensive manufacturing method thereof.
(課題を解決するための手段)
上記目的を達成するため、本発明では、水ガラスにより
封孔処理されたセラミックス層をロール表面に設けるの
である。(Means for Solving the Problems) In order to achieve the above object, in the present invention, a ceramic layer sealed with water glass is provided on the roll surface.
かかるロールはロール表面にセラミックスを被覆してか

り、真空中で予熱して、その後真空中で水ガラス液に浸
漬させる。この場合、特に制限されないが、真空度は1
〜10− ’Torr程度の低い真空度で十分である。Such a roll is manufactured by coating the roll surface with ceramics and then sealing the roll using the following method. That is, it is preheated in a vacuum and then immersed in a water glass solution in a vacuum. In this case, although not particularly limited, the degree of vacuum is 1
A low degree of vacuum on the order of ~10-' Torr is sufficient.
真空中での予熱処理は脱ガスを目的に行うのであって、

。Preheating treatment in vacuum is performed for the purpose of degassing,
The degree of vacuum is not limited as long as degassing is performed, but if degassing is performed in a vacuum, the degassing effect can be further improved by preheating a roll with a ceramic coating layer in vacuum before degassing. Good sealing can be performed.
水ガラスにより封孔を行ってからは所望により乾燥処理
を行ってもよい。After sealing with water glass, drying treatment may be performed as desired.
〈作用)
次に、本発明の構成についてさらに具体的にを説明する
。<Function> Next, the configuration of the present invention will be explained in more detail.
ロール表面を被覆するセラミックス層は、例えば従来の
ような溶射被膜であってもよく、あるいは蒸着法、電気
泳動法等のような多孔質被膜であってもよい。組成的に
は八Q20.のようなアルミナ系、WC,TiCのよう
なカーバイト系等であってもよく、特定のものに制限さ
れない。かかるセラミックス層自体はすでに公知であり
、その製造法もすでに慣用的に行われているもので十分
であり、以下説明を簡潔にするためにこれ以上の説明を
省略する。The ceramic layer covering the roll surface may be, for example, a conventional thermal spray coating, or a porous coating formed by vapor deposition, electrophoresis, or the like. In terms of composition, it is 8Q20. It may be alumina-based such as WC, carbide-based such as TiC, etc., and is not limited to a specific one. Such a ceramic layer itself is already known, and the manufacturing method thereof is already conventionally used. Therefore, further explanation will be omitted for the sake of brevity.
封孔処理前にセラミックス被膜層からの脱ガスを行うた
め予熱を行うが、あまり高温で処理すると、ロール自体
の材質に影響を及ぼし、一方、余り低温でも脱ガス効果
がなくなることから、好ましくは100〜300″Cの
間で処理するのが良い。Preheating is performed to degas the ceramic coating layer before the sealing treatment, but if the treatment is performed at too high a temperature, it will affect the material of the roll itself, and on the other hand, if the temperature is too low, the degassing effect will be lost, so it is preferable. It is best to process at a temperature between 100 and 300''C.
脱ガス時間については、脱ガス効果に関係するため、長
い方が良いが、あまり長すぎても効果はそれ捏上がらな
いため好ましくは1時間以内で行うのが良い。Regarding the degassing time, it is related to the degassing effect, so the longer the better, but if it is too long, the effect will not be improved, so it is preferably carried out within 1 hour.
本発明においては、脱ガス処理時の真空度については、
高真空度は不要で、1〜10−’Torr程度の低真空
度で十分であり、このため特殊な真空ポンプを使う必要
がないため、真空装置自体コストも低く、従って処理コ
ストも安価となる。In the present invention, the degree of vacuum during degassing treatment is as follows:
There is no need for a high degree of vacuum, and a low degree of vacuum of about 1 to 10-'Torr is sufficient.Therefore, there is no need to use a special vacuum pump, so the cost of the vacuum equipment itself is low, and therefore the processing cost is also low. .
次に、上述のように処理されたロールに封孔処理を施す
場合、ロール自体を水ガラス液に浸漬させる方法もある
が、好ましくは第1図に示すように一部分のみ浸漬させ
、ロールを回転させなから封孔処理を行うことも可能で
ある。Next, when performing sealing treatment on the roll treated as described above, there is a method of immersing the roll itself in water glass liquid, but preferably only a portion is immersed as shown in Figure 1, and the roll is rotated. It is also possible to perform pore sealing treatment without leaving it.
図中、セラミックス被覆層10を備えたロール12はカ
ップリング14を経てモータMで回転支持されながら容
器16に収容された水ガラス液18に浸漬され、封孔処
理が行われる。In the figure, a roll 12 provided with a ceramic coating layer 10 is immersed in a water glass liquid 18 contained in a container 16 while being rotatably supported by a motor M via a coupling 14, and a sealing process is performed.
このように、本発明による方法であれば、処理装置自体
もコンパクトになり、水ガラスの消費量も少なくなり、
処理コストも宮くなる。In this way, with the method according to the present invention, the processing equipment itself becomes compact, the amount of water glass consumed is reduced,
Processing costs will also go up.
本発明では処理液に水ガラス液を用いたが、他の処理液
、例えばSt樹脂やエチルシリケート液では、得られる
ロールを高温でのめっき液に用いた際、耐食性に劣るこ
とが、発明者らのラボテストにより判明した。In the present invention, a water glass solution was used as the processing solution, but the inventors have discovered that other processing solutions, such as St resin or ethyl silicate solution, have poor corrosion resistance when the resulting roll is used in a high-temperature plating solution. This was revealed through laboratory tests.
水ガラスは、その上成分がSing、Nanoであるケ
イ酸ソーダであり、水で薄めて使用する。好ましい組成
は5iOi:4〜5 wt%およびNatO:1〜3
wt%である。Water glass is a sodium silicate whose additional ingredient is Sing, Nano, and is used diluted with water. The preferred composition is 5iOi: 4-5 wt% and NatO: 1-3
It is wt%.
封孔処理終了後、必要により乾燥処理を行ってもよく、
その場合の乾R温度については、水ガラスの成分により
、異なるため特に規制はしていないが、好ましくは30
0〜500 ”Cである。After completion of the sealing process, a drying process may be performed if necessary.
In that case, the drying R temperature is not particularly regulated as it varies depending on the components of the water glass, but it is preferably 30
0~500''C.
