Description

【0001】
【発明の属する技術分野】
本発明は、巻取り前の冷延鋼帯又は表面処理鋼帯への防錆油塗油方法に関する。
【0002】
【従来の技術】
一般に、冷間圧延後、巻取り前の鋼帯への防錆油の塗油はスプレー式、静電塗油式のような方式によって行われている。通常、鋼帯への防錆油の塗油は、鋼帯の両面に幅全面に塗油する方法が行われているが、特開平2−220709号公報に示されているように片面のみに塗油する方法も知られている。
【0003】
なお、鋼帯の圧延の圧延油の供給については、特開平2−55604号公報にステンレス鋼帯のエッジシーム疵防止のために鋼帯中央部のみに圧延油を適用して圧延する技術が開示されており、特開平5−69026号公報には圧延油ヘッダの噴射幅を、鋼帯幅に対応した寸法に調整するために、可変とする技術が開示されている。
【0004】
【発明が解決しようとする課題】
鋼帯の両面に鋼帯の全幅に亘って防錆油を塗油すると、鋼帯をコイル状に巻いた時に毛細管現象によってコイルのエッジ端から油が滲み出し、コイル置場を汚すという問題があった。また、鋼帯の片面のみに防錆油を塗油すると、コイルの最内巻又は最外巻の鋼帯に無塗油部分が発生することから錆が発生しやすいという問題があった。
【0005】
また、特開平2−55604号公報、特開平5−69026号公報に開示される技術は前記問題点を解決する物ではなかった。特に特開平2−55604号公報に開示される技術では、圧延油がエッジ部に塗油されないため、エッジ部において錆が発生しやすいという問題があった。
【0006】
本発明はこのような問題点を解決した防錆油塗油技術を提供することを目的とするものである。
【0007】
【課題を解決するための手段】
本発明は、前記課題を解決するためになされたもので、第1の発明は巻取り前の冷延鋼帯又は表面処理鋼帯に防錆油を塗油するに当たり、鋼帯の何れか一方の面は鋼帯の幅方向エッジ部を除く領域に塗油を施し、他方の面は鋼帯全面に塗油することを特徴とする鋼帯への塗油方法である。この第1の発明では鋼帯の両面のうち何れか一方の面(例えば鋼帯下面)の防錆油塗布を鋼帯の幅方向両エッジ部を除く中央領域に塗油するようにしたものである。
【0008】
本発明では、鋼帯をコイル状に巻取る前のライン通板時に、鋼帯の何れか一方の面は鋼帯幅の両エッジ部を除く領域に防錆油を塗油することとし、他方の面は鋼帯全面に塗油することとしたので、鋼帯をコイル状に巻いた時のコイルエッジ端の塗油付着量をセンター部よりも少なくすることができる。なお、鋼帯のエッジ部を除く領域に塗油する面は、塗油位置における鋼帯の下面とする方が好ましい。これは上面では塗油が鋼帯エッジ部に拡散する傾向があるのに比し、下面ではその傾向が小さくエッジ部の無塗油部分の寸法が正確に定めることが容易で、目的を達成しやすいという理由によるものである。
【0009】
本発明の第2の発明は、巻取り前の冷延鋼帯又は表面処理鋼帯に防錆油を塗油するに当たり、鋼帯の何れか一方の面は鋼帯の幅方向の一方のエッジ部を除く領域に塗油を施し、他方の面は他方のエッジ部を除く領域に塗油を施すことを特徴とする鋼帯への塗油方法である。この場合も、上記第1の発明と同様に鋼帯をコイル状に巻いた時のエッジ部の塗油付着量をセンター部よりも少なくすることができるという作用効果を得ることができる。
【0010】
本発明では、防錆油が毛細管現象によりエッジ方向に流出してきても、コイルのエッジ端面から滲み出すことなく、鋼帯をコイル状に巻取った時にエッジ部の無塗油部分にも他方の面の油が転写するため、防錆効果も得られる。
【0011】
鋼帯エッジ部の塗油しない領域の範囲は、鋼帯の種類、サイズ、塗油量等の条件に応じて、鋼帯コイル端面から油の滲み出る状況を観察し、この観察に基づいて条件ごとに定めるとよい。通常は、鋼帯のエッジ端から30〜200mm幅の部分を塗油しない領域とするのがよい。この塗油しない領域の幅が過小ではコイル端部からの油の滲み出しを生じ本発明の効果が乏しく、過大になると油切れによる錆発生の問題が生ずるので不可である。
【0012】
次に、本発明において、前記エッジ部を除く領域に施す塗油を、鋼帯の長手方向先端及び尾端近傍では塗油量を増加するか、又は鋼帯の長手方向先端及び尾端近傍ではエッジ部にも施すことが好ましい。これはコイルの最内巻又は最外巻の鋼帯に無塗油部分が発生することから錆が発生しやすいという問題を防止するためである。この技術手段は鋼帯の圧延などを制御するコンピュータのトラッキング情報を利用して鋼帯長手方向先端又は尾端近傍での塗油装置の塗油量又は塗油領域を変更する手段を付加することによって実現することができる。
【0013】
【発明の実施の形態】
以下図面を参照して本発明の実施の形態を説明する。図1は、本発明の一実施例の塗油方法を説明する正面図(鋼帯の横断面図)である。鋼帯1は表面側塗油装置2、裏面側塗油装置3から油4を供給して塗油される。鋼帯1の裏面側塗油装置3からの防錆油塗油幅を鋼帯1の幅より無塗油部5の幅だけ狭くしたので、鋼帯1をコイル状に巻取った時、コイルのエッジ端面から油が滲み出すことを防止することができ、コイル置き場を汚さないという良好な結果が得られた。
【0014】
図2は別の実施例の鋼帯断面を示したものである。上面の塗油領域6は図2の向かって右側にあり、無塗油部5は向かって左側となっている。下面の塗油領域6は図2の向かって右側にあり、無塗油部5は向かって左側となっている。このようにすると、鋼帯をコイル状に巻いたとき鋼帯の上下面が接し、無塗油部は相手側の面の塗油量が転写されることなり、エッジ部付近は塗油量が少なく、中央部分の塗油量が多くなる。従って、コイル置場を汚染することなく防錆効果を好適に達成することができる。
【0015】
なお、コイルの最内巻及び最外巻の部分に転写のない部分が生ずるのを防ぐために、前記エッジ部を除く領域に施す防錆油の塗油を、鋼帯の長手方向先端及び尾端近傍では塗油量を増加し、又はエッジ部にも塗油することとすればさらに好適である。
【0016】
図1に示す装置を用いて、鋼帯1の下面の無塗油部の幅を50mmとして板幅1200〜2000mmの鋼帯に防錆油を塗油した。塗油量は片面あたり0.8〜0.9g/m2である。数ヶ月の観察によれば、コイルエッジ端からの油の滲み出しが著しく減少した。また、発錆も見られなかった。
【0017】
【発明の効果】
本発明は鋼帯の防錆油塗油幅をエッジ部を除く領域に施すこととしたので、鋼帯をコイル状に巻取った時に、コイルエッジ端から油の滲み出しや流出を防止することができるようになった。また、コイルエッジ端からの油の滲み出しがないことから、コイル置場が汚れることがなく、さらに、過剰な防錆油の使用を削減することができるという効果もある。

BACKGROUND OF THE INVENTION
The present invention relates to a method for applying a rust preventive oil to a cold-rolled steel strip or a surface-treated steel strip before winding.
[0002]
[Prior art]
Generally, after cold rolling, the rust-preventive oil is applied to the steel strip before winding by a system such as a spray type or an electrostatic oil type. Usually, the rust preventive oil is applied to the steel strip by a method of applying the entire width of the steel strip to the entire width, but only on one side as disclosed in JP-A-2-220709. An oiling method is also known.
[0003]
Regarding the supply of rolling oil for rolling steel strips, Japanese Patent Application Laid-Open No. 2-55604 discloses a technique for rolling by applying rolling oil only to the central portion of the steel strip to prevent edge seam flaws in the stainless steel strip. JP-A-5-69026 discloses a technique for making the injection width of the rolling oil header variable in order to adjust the injection width to a dimension corresponding to the steel strip width.
[0004]
[Problems to be solved by the invention]
When anti-rust oil is applied to both sides of the steel strip over the entire width of the steel strip, there is a problem that when the steel strip is wound into a coil shape, oil oozes out from the edge of the coil due to capillary action and soils the coil place. It was. In addition, when rust preventive oil is applied to only one surface of the steel strip, there is a problem that rust is likely to occur because an oil-free portion is generated in the innermost or outermost steel strip of the coil.
[0005]
In addition, the techniques disclosed in JP-A-2-55604 and JP-A-5-69026 have not solved the above problems. In particular, the technique disclosed in Japanese Patent Application Laid-Open No. 2-55604 has a problem that rust is likely to occur at the edge portion because the rolling oil is not applied to the edge portion.
[0006]
The object of the present invention is to provide a rust preventive oil coating technique that solves such problems.
[0007]
[Means for Solving the Problems]
The present invention has been made to solve the above-mentioned problems, and the first invention is to apply either anti-corrosion oil to a cold-rolled steel strip or a surface-treated steel strip before winding, and either one of the steel strips. the surface to facilities the oiling to the region except for the widthwise edge portions of the steel strip, the other surface is oiled method to the steel strip, characterized in that the oiled steel strip entirely. In the first aspect of the invention, rust preventive oil application on either one of the surfaces of the steel strip (for example, the bottom surface of the steel strip) is applied to the central region excluding both edge portions in the width direction of the steel strip. is there.
[0008]
In the present invention, at the time of line passing before winding the steel strip into a coil shape, any one surface of the steel strip is coated with rust preventive oil in the region excluding both edge portions of the steel strip width, Since the surface is coated with oil on the entire surface of the steel strip, the amount of oil applied to the coil edge end when the steel strip is wound in a coil shape can be made smaller than that of the center portion. The surface to be oiled in the region excluding the edge of the steel strip is preferably the bottom surface of the steel strip at the oiling position. This is because oil tends to diffuse to the edge of the steel strip on the upper surface, whereas the tendency is small on the lower surface, making it easy to accurately determine the size of the oil-free portion of the edge, and achieving the purpose. This is because it is easy.
[0009]
According to the second aspect of the present invention, when the rust preventive oil is applied to the cold-rolled steel strip or the surface-treated steel strip before winding, any one surface of the steel strip is one edge in the width direction of the steel strip. In this method, oil is applied to the region excluding the portion, and the other surface is applied to the region excluding the other edge portion. Also in this case, as in the first aspect of the invention, it is possible to obtain an operational effect that the amount of oil applied to the edge portion when the steel strip is wound in a coil shape can be made smaller than that of the center portion.
[0010]
In the present invention, even if the rust preventive oil flows out in the edge direction due to capillary action, it does not ooze out from the edge end surface of the coil, and when the steel strip is wound into a coil shape, the other oil-free portion of the edge portion is also applied to the other oil-coated portion. Since the oil on the surface is transferred, a rust prevention effect is also obtained.
[0011]
The range of the region where the steel strip edge is not oiled depends on the conditions such as the type, size, and amount of oil applied to the steel strip. It is good to decide every. Usually, it is good to make it the area | region which does not lubricate the part of 30-200 mm width from the edge end of a steel strip. If the width of the non-oiled region is too small, oil oozes out from the coil end and the effect of the present invention is poor, and if too large, the problem of rust generation due to running out of oil is impossible.
[0012]
Next, in the present invention, the amount of oil applied to the region excluding the edge portion is increased in the vicinity of the longitudinal end and tail end of the steel strip , or in the vicinity of the longitudinal end and tail end of the steel strip. It is preferable to apply also to the edge portion. This is to prevent a problem that rust is likely to be generated because an oil-free portion is generated in the innermost or outermost steel strip of the coil. This technical means is to add means for changing the oil application amount or the oil application area of the oil applicator near the front end or tail end in the longitudinal direction of the steel strip using the tracking information of the computer that controls the rolling of the steel strip. Can be realized.
[0013]
DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a front view (a cross-sectional view of a steel strip) illustrating an oiling method according to an embodiment of the present invention. The steel strip 1 is oiled by supplying oil 4 from the front surface side oiling device 2 and the back surface side oiling device 3. Since the rust preventive oil coating width from the back surface side oiling device 3 of the steel strip 1 is made narrower than the width of the steel strip 1 by the width of the oil-free portion 5, when the steel strip 1 is wound into a coil shape, As a result, it was possible to prevent the oil from seeping out from the edge end surface of the coil, and a good result was obtained that the coil place was not stained.
[0014]
FIG. 2 shows a steel strip cross section of another embodiment. The oiling area 6 on the upper surface is on the right side in FIG. 2, and the oil-free part 5 is on the left side in FIG. The lower surface oil-coated region 6 is on the right side in FIG. 2, and the non-oiled portion 5 is on the left side. In this way, when the steel strip is wound in a coil shape, the upper and lower surfaces of the steel strip come into contact with each other, the amount of oil applied to the non-oiled portion is transferred, and the amount of oil applied near the edge portion is transferred. Less, the amount of oil in the center increases. Therefore, the rust prevention effect can be suitably achieved without contaminating the coil placement.
[0015]
In addition, in order to prevent the portion without the transfer from occurring in the innermost winding and the outermost winding portion of the coil, the rust preventive oil is applied to the region excluding the edge portion in the longitudinal direction tip and tail end of the steel strip. In the vicinity, it is more preferable to increase the amount of oil applied or to apply oil to the edge portion.
[0016]
Using the apparatus shown in FIG. 1, the width of the oil-free portion on the lower surface of the steel strip 1 was 50 mm, and antirust oil was applied to the steel strip having a plate width of 1200 to 2000 mm. The amount of oil coating is 0.8 to 0.9 g / m 2 per side. According to observations for several months, oil oozing from the coil edge ends was significantly reduced. Moreover, rusting was not seen.
[0017]
【The invention's effect】
In the present invention, the rust-preventive oil coating width of the steel strip is applied to the region excluding the edge portion, so that when the steel strip is wound in a coil shape, oil exudation or outflow from the end of the coil edge is prevented. Can now. Further, since no oil oozes out from the end of the coil edge, the coil place is not contaminated, and there is an effect that the use of excessive rust preventive oil can be reduced.
