【発明の詳細な説明】 （産業上の利用分野） 本発明は鋼帯の防錆油塗布量調整方法に関するものであ
る。TECHNICAL FIELD The present invention relates to a method for adjusting the amount of rust-preventing oil applied to a steel strip.
（従来技術） 鋼帯には防錆を目的として油を塗布するが、その塗布量
の要求量によつて塗布する装置が幾種類もある。(Prior Art) Oil is applied to a steel strip for the purpose of rust prevention, but there are various types of devices for applying oil according to the required amount of the oil.
油の供給方法としてブラシロールのハネかけ、ロールに
よるコーテイング、スプレー吹きかけなどで、その後ゴ
ムまたは不織布ロールで絞り付着量を均一化している。
また極めて低目付の塗布には油をイオン化させ、電位を
与えた鋼帯に電気的に付着させる静電塗油装置がある
が、設備費が高価である。As a method of supplying oil, brushing with a brush roll, coating with a roll, spraying or the like is performed, and then a rubber or non-woven fabric roll is used to uniformize the amount of adhesion.
In addition, there is an electrostatic oiling device that ionizes oil and electrically attaches it to a steel strip to which an electric potential has been applied for coating with a very low basis weight, but the equipment cost is high.
厚目塗油を対象にした設備では塗布制御が手動、自動に

油に限界があり、低目狙いが困難となる。また成品によ
つて要求仕様が数百mg/m2から数千mg/m2まで変化するこ
とになり、従来の塗油技術では不可能であつた。In the equipment for thick oil coating, whether the coating control is manual or automatic, oil is supplied abundantly and there is a limit to the oil that can be removed by squeezing the roll, making it difficult to aim at a low target. In addition, depending on the product, the required specifications will change from several hundred mg / m 2 to several thousand mg / m 2 , which was not possible with conventional oiling technology.

状態に油ムラが発生する危惧もある。(Problems to be Solved by the Invention) As a development of these techniques, JP-A-60-106981 discloses a method of removing oil by a suction device using a sponge and adjusting the sponge. It has poor durability and is not practical in a process line where it is operated continuously, and there is a risk that oil spots will occur on the final surface due to damage to the sponge.
（問題点を解決するための手段） 本発明は前述の問題点を解決し、従来にない新規な塗布

面均一化を行うものである。The gist of the present invention is to supply rust preventive oil to a steel strip, and squeeze the rust preventive oil attached to the steel strip by an oil suction roll having a structure in which a nonwoven fabric sheet is laminated or wound around a perforated hollow iron core. A method for adjusting the amount of rust preventive oil applied to a steel strip, which comprises adjusting the oil film thickness. At that time, the method of supplying the rust preventive oil may be any of the same spray, brushing, roll coater, etc. as in the conventional method, but excess oil is removed outside the system by using a vacuum suction oil suction roll that is rotated by being carried by the steel strip. , To make the surface uniform.
次に本発明を図面を用いて詳細に説明する。Next, the present invention will be described in detail with reference to the drawings.
移動する鋼帯１の上下に、鋼帯を幅方向に横断するよう
に設けた塗布装置２で鋼帯１に防錆油を塗布する。この
塗布に際しては防錆油タンク３から油供給ポンプ４によ
り流量調整弁５を介して油量を調整して塗布装置２に防
錆油を供給するようになつている。Rust-preventing oil is applied to the steel strip 1 by a coating device 2 provided above and below the moving steel strip 1 so as to traverse the steel strip in the width direction. In this application, the amount of oil is adjusted from the rust preventive oil tank 3 by the oil supply pump 4 via the flow rate adjusting valve 5, and the rust preventive oil is supplied to the coating device 2.
塗布装置２の下流には油吸引ロール７を設置し、供給さ
れた油の過剰分を吸いとることにより薄目塗油が可能に
なる。An oil suction roll 7 is installed on the downstream side of the coating device 2 to absorb an excessive amount of the supplied oil, thereby enabling thin coating oil.
吸引ロール７は第２図に示すように孔明き中空鉄芯19に
不織布シート22を積層または巻き付けた構造をしてお
り、真空ポンプ８と圧力調整弁９、油分回収器10、吸引
管11とつながつている。As shown in FIG. 2, the suction roll 7 has a structure in which a nonwoven fabric sheet 22 is laminated or wound around a hollow hollow iron core 19, and a vacuum pump 8, a pressure control valve 9, an oil recovery unit 10, and a suction pipe 11 are provided. It is connected.
鋼帯１よりロール７に吸いとられた油分は鉄芯19の孔17
から軸の中空部18を通り、油分回収器10から配管14を通
つて油タンク３に回収される。The oil absorbed by the roll 7 from the steel strip 1 is the hole 17 of the iron core 19.
The oil is collected in the oil tank 3 through the hollow portion 18 of the shaft, the oil collector 10 and the pipe 14.
ロールからの回収方法として、ロール表面で鋼帯１から
離れたところに真空吸引ボツクス21を取りつけ、このボ
ツクス21を通して、油を戻す構造も可能で、どちらを使
用するかは切り替え弁23で選択すれば良い。As a method of recovering from the roll, it is also possible to attach a vacuum suction box 21 to a place apart from the steel strip 1 on the surface of the roll, and to return oil through this box 21, which can be selected by the switching valve 23. Good.
また、吸引ロール7,7′の下流には油膜厚計15を用いる
場合は、該油膜計15からの検出信号を圧力調整弁９に送
り吸引圧力をコントロールして油膜厚を調整するもので
ある。When an oil film thickness meter 15 is used downstream of the suction rolls 7, 7 ', a detection signal from the oil film meter 15 is sent to the pressure adjusting valve 9 to control the suction pressure to adjust the oil film thickness. .
このようにして油膜厚の調整を行うものであるが、鋼帯
の出側に油量検出器を用いて真空圧をコントロールして
所要の付着量に調整しても良い。Although the oil film thickness is adjusted in this way, the oil amount detector may be used on the outlet side of the steel strip to control the vacuum pressure to adjust the amount of adhesion to the required amount.
即ち、多量の油を油吸引ロールに用いる不織布ロールの
毛細管現象と真空吸引を利用することで、ロールの損傷
もなく防錆油の原単位を向上させることができるもので
ある。That is, by utilizing the capillarity and vacuum suction of a non-woven fabric roll that uses a large amount of oil for the oil suction roll, it is possible to improve the basic unit of rust preventive oil without damaging the roll.
一方、多目塗油でスプレー等の供給では不足する場合
は、この不織布ロールに圧油を送りこむ配管を備えてお
けば、更に付着量の制御範囲が拡大するものである。On the other hand, if the supply of spray or the like is insufficient due to the multi-layered coating oil, a pipe for feeding pressure oil to the non-woven fabric roll is provided to further expand the control range of the adhered amount.
更に、本発明の油吸引ロールは油を吸引する働きと共に
鋼帯に付着している油を絞る働きも備えている。即ち、
鋼帯に多目に付着している防錆油は油吸引ロールで絞り
が行われ、１部の防錆油はラインサイドに除去される。
そして残つている防錆油を吸引ロールで吸引することに
より、塗布量の調整を行うものである。Further, the oil suction roll of the present invention has a function of sucking oil and a function of squeezing the oil adhering to the steel strip. That is,
The rust preventive oil that adheres to the steel strip a lot is squeezed by an oil suction roll, and a part of the rust preventive oil is removed to the line side.
Then, the remaining rust preventive oil is sucked with a suction roll to adjust the coating amount.
従つて、本発明によれば鋼帯に防錆油を塗布した後、通
常、設けられている絞りロールを設置しなくても、塗布
量の調整が可能である。Therefore, according to the present invention, after the rust preventive oil is applied to the steel strip, the application amount can be adjusted without installing the squeezing roll which is usually provided.
また一旦、毛細管現象で吸い取られた防錆油はロール外
へ真空吸引で回収するのであるが、軸内部を通す方法で
も、ロール表面から真空ボツクスを設けて戻す方法のい
ずれでも良い。防錆油の塗布装置についてもスプレー方
式、ロールコーター方式等どの方式を用いても良く、そ
の手段は特にこだわるものでない。Further, the rust preventive oil once sucked by the capillary phenomenon is collected outside the roll by vacuum suction, but either a method of passing the inside of the shaft or a method of providing a vacuum box from the roll surface and returning it may be used. The rust preventive oil coating device may be of any type such as a spray type or a roll coater type, and the means is not particularly limited.
実施例 厚みが0.8mmで幅が1000mmの冷延コイルを捲戻しライン
速度200mpmで通板し、その時、下記の塗布方式で防錆油
（ノツクスラスト）を塗布した。その結果、第１表のよ
うな結果を得た。Example A cold rolled coil having a thickness of 0.8 mm and a width of 1000 mm was threaded at a rewinding line speed of 200 mpm, at which time, a rust preventive oil (Knotxlast) was applied by the following application method. As a result, the results shown in Table 1 were obtained.
第１表の如く、本発明によれば従来法に比べて防錆油の
均一塗布が可能であることが明らかである。 As shown in Table 1, according to the present invention, it is apparent that the rust preventive oil can be applied more uniformly than the conventional method.
（発明の効果） 本発明によれば防錆油の塗布量の調整が極めて小さい偏
差で可能となり、その効果は大きいものである。(Effect of the Invention) According to the present invention, the amount of rust preventive oil applied can be adjusted with a very small deviation, and the effect is great.
