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。DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a method for adjusting the amount of antirust 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
の要求量によって塗布する装置が幾種類もある。(Prior Art) Steel strips are coated with oil for the purpose of rust prevention, and there are various types of oil coating devices depending on the required amount of oil to be applied.
油の供給方法としてブラシロールのハネかけ、ロールに
よるコーティング、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。The oil is supplied by brush rolls, coating with a roll, spraying, etc., and then squeezed with a rubber or non-woven roll to make the amount of oil adhered uniform.
また極めて低目付の塗布（＝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。There is also an electrostatic oil coating device that ionizes oil and electrically attaches it to a steel strip that has been given a potential, but the equipment cost is high.

可能であった。In equipment for thick oil application, whether the application control is manual or automatic, oil is supplied in large quantities and oil is removed by the roll squeezing (there are two limits, making it difficult to aim for a low thickness. Depending on the specification, the required specifications range from several hundred m9/rr? to several thousand ~/lr.
? 2), which was impossible with conventional oiling techniques.

面の塗油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 technologies, a method for removing and adjusting oil using a suction device using a sponge was invented in Japanese Patent Application Laid-Open No. 106981/1981. There are problems with the durability of the sponges, making them impractical in process lines that are operated continuously, and there is also the risk that damage to the sponges may result in uneven oil application on the final surface.

It is also durable compared to steel strips (2).
本発明の要旨は鋼帯に防錆油を供給後、油吸引ロール（
二より鋼帯に付着している防錆油を絞るとともに油膜厚
を調整することを特徴としている。The gist of the present invention is that after supplying rust preventive oil to the steel strip, the oil suction roll (
It is characterized by squeezing out the rust preventive oil adhering to the steel strip and adjusting the oil film thickness.
その時の防錆油の供給方法は従来と同じスプレー、プラ
シングはねかけ、ロールコータ−等いずれでも良いが、
余分な油を鋼帯につられて回転する真空吸引の油吸引ロ

ある。At that time, the method of supplying the rust preventive oil can be the same as before, such as spraying, plastic splashing, roll coater, etc.
Excess oil is removed from the system using a rotating vacuum oil suction roll attached to a steel strip, and the surface is made 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 explained in detail using the drawings.
移動する鋼帯１の上下ζ−１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；、１４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っている。Rust preventive oil is applied to the steel strip 1 by a coating device 2 provided so as to cross the upper and lower ζ-1 steel strips in the width direction of the moving steel strip 1. During this application, the rust preventive oil is supplied from the rust preventive oil tank 3 to the coating device 2 by adjusting the flow rate and the amount of oil via an oil supply pump 4 and a 14 regulating valve 5.
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：二よυ薄目塗油が可能
）二なる。An oil suction roll 7 is installed downstream of the coating device 2 to suck up the excess amount of the supplied oil: 2.
吸引ロール７は第２図（＝示すよう（二孔明き中空鉄芯

0, connected to the suction tube 11.
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
管工４を通って油タンク３に回収される。The oil absorbed by the roll 7 from the steel strip 1 passes through the hole 17 of the iron core 19 through the hollow part 18 of the shaft, passes from the oil collector 10 to the plumber 4, and is collected in the oil tank 3.
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ックス２１を取りつけ、この
ボックス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 the oil from the roll, it is also possible to install a vacuum suction box 21 on the roll surface away from the steel strip 1 and return the oil through this box 21, and which one to use can be selected with the switching valve 23. Good.
また、吸引ロール７．７′の下流には油膜淳計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。Further, when an oil film gauge 15 is used downstream of the suction roll 7, 7', a detection signal from the oil film gauge 15 is sent to the pressure regulating valve 9 to control the suction pressure and 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, it is also possible to control the vacuum pressure using an oil amount detector on the exit side of the steel strip 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 capillary action and vacuum suction of the nonwoven fabric roll that uses a large amount of oil in the oil suction roll, the unit consumption of rust preventive oil can be improved without damaging the roll.
一万、条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。If the supply of oil by spraying or the like is insufficient for applying oil in stripes, the control range of the amount of adhesion can be further expanded by providing piping to send pressure oil to the nonwoven fabric roll.
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、
鋼帯に多口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。Furthermore, the oil suction roll of the present invention has the function of sucking oil as well as squeezing out oil adhering to the steel strip. That is,
The rust preventive oil adhering to the steel strip in large quantities is squeezed out by an oil suction roll, and a portion of the rust preventive oil is removed to the line side.
そして残っ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。The amount of application is then adjusted by sucking up the remaining rust preventive oil with a suction roll.
従って、本発明（＝よれば鋼帯に防錆油を塗布した後、

布量の調整が可能である。Therefore, according to the present invention (=, after applying antirust oil to the steel strip,
The amount of coating can be adjusted without installing the normally provided squeezing roll.

の手段は特にこだわるものでない。Furthermore, the anticorrosive oil that has been sucked out by capillary action is recovered by vacuum suction to the outside of the roll, but it may be returned by passing it through the inside of the shaft or by providing a vacuum box from the surface of the roll. As for the rust-preventing oil application device, any method such as a spray type, a roll coater type, etc. may be used, and the method is not particularly limited.
