Abstract

PROBLEM TO BE SOLVED: To solve such the problem that since the conventional polishing belt for removing a surface scale is structured so that the surface scale is ground by abrasive grains directly stuck to the surface of a belt body, it is difficult to make clogging of the polishing belt be hardly caused and to suppress consumption of abrasive grains in an edge part, at the same time, and service life of the polishing belt is short.SOLUTION: Abrasive grains 32 in sliding contact with a steel strip 1 after hot rolling is ended are stuck to the outer surface of a plurality of granular elastic bodies 31 disposed on the surface of a belt body 30.

Description

本発明は、表面スケール除去用の研磨ベルト、及びそれを用いた鋼帯製造方法に関し、特に、熱間圧延が終了された後の鋼帯に対して摺接される砥粒を、ベルト本体の表面に設けられた複数の粒状弾性体の外面に付着させるように構成することで、研磨ベルトの目詰まりを起こしにくくすることができるとともに、エッジ部分における砥粒の消耗を抑えることができ、研磨ベルトの寿命を長くできるようにするための新規な改良に関するものである。   The present invention relates to a polishing belt for removing a surface scale, and a steel strip manufacturing method using the same, and in particular, abrasive grains slidably contacted with a steel strip after hot rolling has been completed. By being configured to adhere to the outer surface of a plurality of granular elastic bodies provided on the surface, clogging of the polishing belt can be made difficult to occur, and consumption of abrasive grains at the edge portion can be suppressed, and polishing can be performed. The present invention relates to a new improvement for extending the life of a belt.

一般に、熱間圧延が終了された後の鋼帯の表面にスケール（酸化物被膜）が付着することが知られている。例えば下記の特許文献１等に示されている従来構成では、熱間圧延が終了された後の鋼帯に対して研磨ベルトの研磨面を摺接させることにより、鋼帯の表面スケールを研削している。   In general, it is known that scale (oxide film) adheres to the surface of a steel strip after hot rolling is finished. For example, in the conventional configuration shown in the following Patent Document 1, etc., the surface scale of the steel strip is ground by bringing the polishing surface of the polishing belt into sliding contact with the steel strip after the hot rolling is finished. ing.

図３は、従来の研磨ベルト９の研磨面を示す構成図である。図において、研磨ベルト９には、ベルト本体９０及び複数の砥粒９１が設けられている。ベルト本体９０は、布又は紙により構成された無端状の帯状部材である。砥粒９１は、鋼帯の表面スケールを研削するための硬質部材であり、接着剤９２によりベルト本体９０の表面に直接付着されている。この砥粒９１としては、例えばアルミナ砥粒やＳｉＣ砥粒等が用いられる。   FIG. 3 is a configuration diagram showing a polishing surface of a conventional polishing belt 9. In the figure, the polishing belt 9 is provided with a belt main body 90 and a plurality of abrasive grains 91. The belt main body 90 is an endless belt-like member made of cloth or paper. The abrasive grain 91 is a hard member for grinding the surface scale of the steel strip, and is directly attached to the surface of the belt main body 90 by an adhesive 92. As this abrasive grain 91, an alumina abrasive grain, a SiC abrasive grain, etc. are used, for example.

特開平７−２７６２１３号公報JP 7-276213 A

上記のような従来構成では、ベルト本体９０の表面に直接付着された砥粒９１により表面スケールを研削するように構成されているので、以下の問題が生じる。
すなわち、砥粒９１としてアルミナ砥粒を用いる場合には、アルミナが硬質なために、表面スケールを研削しても砥粒９１が破砕されにくく、砥粒９１間に詰った表面スケール９３が除去される可能性が少ない。すなわち、表面スケール９３により研磨ベルト９が目詰まりしやすく、研磨ベルト９の寿命が短くなっている。
また、砥粒９１としてＳｉＣ砥粒が用いられる場合には、ＳｉＣ砥粒がアルミナ砥粒に比べて破砕されやすいので、砥粒９１間に詰った表面スケール９３が砥粒９１の破砕により除去される可能性がある。しかしながら、鋼帯のエッジ部分において研磨ベルト９に大きな負荷が掛るため、エッジ部分において砥粒９１が多く破砕される。すなわち、エッジ部分における砥粒９１の消耗が早く、研磨ベルト９の寿命が短くなっている。 In the conventional configuration as described above, the surface scale is ground by the abrasive grains 91 directly attached to the surface of the belt main body 90, so the following problems arise.
That is, when alumina abrasive grains are used as the abrasive grains 91, since the alumina is hard, the abrasive grains 91 are hardly crushed even if the surface scale is ground, and the surface scale 93 clogged between the abrasive grains 91 is removed. There is little possibility of being. That is, the polishing belt 9 is easily clogged by the surface scale 93, and the life of the polishing belt 9 is shortened.
In addition, when SiC abrasive grains are used as the abrasive grains 91, the SiC abrasive grains are more easily crushed than alumina abrasive grains, so that the surface scale 93 clogged between the abrasive grains 91 is removed by crushing the abrasive grains 91. There is a possibility. However, since a large load is applied to the polishing belt 9 at the edge portion of the steel strip, many abrasive grains 91 are crushed at the edge portion. That is, the wear of the abrasive grains 91 at the edge portion is fast, and the life of the polishing belt 9 is shortened.

本発明は、上記のような課題を解決するためになされたものであり、その目的は、研磨ベルトの目詰まりを起こしにくくすることができるとともに、エッジ部分における砥粒の消耗を抑えることができ、研磨ベルトの寿命を長くできる表面スケール除去用の研磨ベルト、及びそれを用いた鋼帯製造方法を提供することである。   The present invention has been made to solve the above-described problems, and the object thereof is to make it difficult to cause clogging of the polishing belt and to suppress the consumption of abrasive grains at the edge portion. An object of the present invention is to provide a polishing belt for removing a surface scale that can prolong the life of the polishing belt, and a method for producing a steel strip using the same.

本発明に係る表面スケール除去用の研磨ベルトは、ベルト本体と、ベルト本体の表面に設けられた複数の粒状弾性体と、各粒状弾性体の外面に付着された複数の砥粒とを備え、熱間圧延が終了された後の鋼帯に対して、各粒状弾性体の外面に付着された砥粒が摺接されることより、鋼帯の表面スケールを研削するように構成されている。
粒状弾性体がコルクであり、砥粒がＳｉＣであることが好ましい。 A polishing belt for removing a surface scale according to the present invention comprises a belt main body, a plurality of granular elastic bodies provided on the surface of the belt main body, and a plurality of abrasive grains attached to the outer surface of each granular elastic body, It is configured to grind the surface scale of the steel strip by sliding the abrasive grains attached to the outer surface of each granular elastic body to the steel strip after the hot rolling is finished.
The granular elastic body is preferably cork and the abrasive grains are preferably SiC.

また、本発明に係る鋼帯製造方法は、ベルト本体と、ベルト本体の表面に設けられた複数の粒状弾性体と、各粒状弾性体の外面に付着された複数の砥粒とを有する研磨ベルトを用い、熱間圧延が終了された後の鋼帯に対して、各粒状弾性体の外面に付着された砥粒を摺接させることより、表面スケールが除去された鋼帯を製造する。
粒状弾性体がコルクであり、砥粒がＳｉＣであることが好ましい。 Moreover, the steel strip manufacturing method according to the present invention includes a belt body, a plurality of granular elastic bodies provided on the surface of the belt main body, and a plurality of abrasive grains attached to the outer surface of each granular elastic body. The steel strip from which the surface scale has been removed is manufactured by sliding the abrasive grains attached to the outer surface of each granular elastic body against the steel strip after the hot rolling is finished.
The granular elastic body is preferably cork and the abrasive grains are preferably SiC.

本発明の表面スケール除去用の研磨ベルト、及びそれを用いた鋼帯製造方法によれば、
熱間圧延が終了された後の鋼帯に対して摺接される砥粒を、ベルト本体の表面に設けられた複数の粒状弾性体の外面に付着させるように構成するので、砥粒間に詰った表面スケールを粒状弾性体の振動により除去できる。また、鋼帯のエッジ部分における研磨ベルトへの負荷を粒状弾性体により吸収できる。これにより、研磨ベルトの目詰まりを起こしにくくすることができるとともに、エッジ部分における砥粒の消耗を抑えることができ、研磨ベルトの寿命を長くできる。 According to the polishing belt for surface scale removal of the present invention and the steel strip manufacturing method using the same,
Since the abrasive grains slidably contacted with the steel strip after the hot rolling is completed are configured to adhere to the outer surfaces of the plurality of granular elastic bodies provided on the surface of the belt body, The clogged surface scale can be removed by the vibration of the granular elastic body. Moreover, the load to the grinding | polishing belt in the edge part of a steel strip can be absorbed with a granular elastic body. As a result, clogging of the polishing belt can be made difficult to occur, wear of the abrasive grains at the edge portion can be suppressed, and the life of the polishing belt can be extended.

FIG.

以下、本発明を実施するための形態について、図面を参照して説明する。
実施の形態１．
図１は、本発明の実施の形態１による鋼帯製造装置を示す構成図である。図において、鋼帯製造装置には、鋼帯１が搬送されるライン方向１ａに沿って直列に配置された複数の研磨スタンド２が設けられている。これら研磨スタンド２は、周知の熱間圧延スタンド（図示せず）の後段に配置されている。なお、図１では、３つの研磨スタンド２が設置されるように示しているが、設置される研磨スタンド２の段数は任意である。 Hereinafter, embodiments for carrying out the present invention will be described with reference to the drawings.
Embodiment 1 FIG.
FIG. 1 is a configuration diagram showing a steel strip manufacturing apparatus according to Embodiment 1 of the present invention. In the figure, the steel strip manufacturing apparatus is provided with a plurality of polishing stands 2 arranged in series along the line direction 1a along which the steel strip 1 is conveyed. These polishing stands 2 are arranged in a subsequent stage of a known hot rolling stand (not shown). Although FIG. 1 shows that three polishing stands 2 are installed, the number of stages of the polishing stands 2 to be installed is arbitrary.

各研磨スタンド２には、研磨ベルト３、第１プーリ４、第２プーリ５、及び支持ローラ６が設けられている。研磨ベルト３は、無端状のベルト体であり、循環可能に（回転走行可能に）第１及び第２プーリ４，５に巻き掛けられている。支持ローラ６は、第２プーリ５の下方に配置されたローラであり、各研磨スタンド２内で鋼帯１を支持する。すなわち、各研磨スタンド２では、鋼帯１が第２プーリ５と支持ローラ６との間を通過する際に、鋼帯１に研磨ベルト３の研磨面が摺接される。   Each polishing stand 2 is provided with a polishing belt 3, a first pulley 4, a second pulley 5, and a support roller 6. The polishing belt 3 is an endless belt body, and is wound around the first and second pulleys 4 and 5 so as to be able to circulate (rotatably run). The support roller 6 is a roller disposed below the second pulley 5 and supports the steel strip 1 in each polishing stand 2. That is, in each polishing stand 2, when the steel strip 1 passes between the second pulley 5 and the support roller 6, the polishing surface of the polishing belt 3 is brought into sliding contact with the steel strip 1.

次に、図２は、図１の研磨ベルト３の研磨面を示す構成図である。図において、研磨ベルト３には、ベルト本体３０、複数の粒状弾性体３１、及び複数の砥粒３２が設けられている。ベルト本体３０は、布又は紙により構成された無端状の帯状部材である。粒状弾性体３１は、例えばコルクやゴム等の弾性体が粒状に形成されたものであり、接着剤３３によりベルト本体３０の表面に付着されている。砥粒３２は、後述の鋼帯１の表面スケールを研削するための硬質部材であり、図示しない接着剤により粒状弾性体３１の外面に付着されている。砥粒３２としては、破砕性が良いＳｉＣ砥粒を用いることが好ましいが、例えばアルミナ砥粒やジルコニア等の他の砥粒を用いてもよい。なお、粒状弾性体３１の粒径が２ｍｍ程度であるのに対して、砥粒３２の粒径は５０μｍ〜１ｍｍ程度である。   Next, FIG. 2 is a block diagram showing a polishing surface of the polishing belt 3 of FIG. In the figure, the polishing belt 3 is provided with a belt body 30, a plurality of granular elastic bodies 31, and a plurality of abrasive grains 32. The belt body 30 is an endless belt-like member made of cloth or paper. The granular elastic body 31 is formed by forming an elastic body such as cork or rubber in a granular form, and is adhered to the surface of the belt main body 30 by an adhesive 33. The abrasive grain 32 is a hard member for grinding the surface scale of the steel strip 1 described later, and is attached to the outer surface of the granular elastic body 31 with an adhesive (not shown). As the abrasive grains 32, SiC abrasive grains having good crushability are preferably used, but other abrasive grains such as alumina abrasive grains and zirconia may be used. The particle diameter of the granular elastic body 31 is about 2 mm, whereas the particle diameter of the abrasive grains 32 is about 50 μm to 1 mm.

次に、図１及び図２の研磨ベルト３を用いた鋼帯製造方法について説明する。周知のように、熱間圧延が終了された後の鋼帯１の表面には、表面スケール（酸化物被膜）が形成されている。図１に示すように、熱間圧延が終了された後の鋼帯１は、各研磨スタンド２の第２プーリ５と支持ローラ６との間を通過される。本実施の形態の鋼帯製造方法では、各研磨スタンド２の第２プーリ５と支持ローラ６との間を通過される際に、各粒状弾性体３１の外面に付着された砥粒３２（図２参照）を鋼帯１に摺接させることにより、鋼帯１の表面スケールを研削して、表面スケールが除去された鋼帯１を製造する。なお、鋼帯１と研磨ベルト３との接触位置には、研磨ベルト３を冷却するための冷却油が供給される。   Next, a steel strip manufacturing method using the polishing belt 3 of FIGS. 1 and 2 will be described. As is well known, a surface scale (oxide film) is formed on the surface of the steel strip 1 after the hot rolling is finished. As shown in FIG. 1, the steel strip 1 after the hot rolling is finished is passed between the second pulley 5 and the support roller 6 of each polishing stand 2. In the steel strip manufacturing method of the present embodiment, when passing between the second pulley 5 and the support roller 6 of each polishing stand 2, the abrasive grains 32 attached to the outer surface of each granular elastic body 31 (see FIG. 2) is brought into sliding contact with the steel strip 1 to grind the surface scale of the steel strip 1 to produce the steel strip 1 from which the surface scale has been removed. A cooling oil for cooling the polishing belt 3 is supplied to a contact position between the steel strip 1 and the polishing belt 3.

ここで、研磨ベルト３の粒状弾性体３１は、鋼帯１に押付けられた際に圧縮されるとともに、研磨ベルト３の循環により鋼帯１への押付けから解放された際に復元される。砥粒３２による表面スケール研削を行うと砥粒３２間に表面スケールが詰ることが考えられるが、圧縮及び復元による粒状弾性体３１の振動により、砥粒３２間から表面スケールを除去し得る。また、鋼帯１のエッジ部分において砥粒３２に大きな負荷が掛ることが考えられるが、砥粒３２への負荷を粒状弾性体３１の弾性により吸収し得る。すなわち、本実施の形態の研磨ベルト３では、研磨ベルト３の目詰まりを起こしにくくすることと、エッジ部分における砥粒３２の消耗を抑えることとを両立できる。   Here, the granular elastic body 31 of the polishing belt 3 is compressed when pressed against the steel strip 1 and is restored when released from pressing against the steel strip 1 by circulation of the polishing belt 3. When surface scale grinding with the abrasive grains 32 is performed, it is considered that the surface scales are clogged between the abrasive grains 32, but the surface scales can be removed from between the abrasive grains 32 by vibration of the granular elastic body 31 due to compression and restoration. Further, although it is conceivable that a large load is applied to the abrasive grains 32 at the edge portion of the steel strip 1, the load on the abrasive grains 32 can be absorbed by the elasticity of the granular elastic body 31. That is, in the polishing belt 3 of the present embodiment, it is possible to make it difficult to cause clogging of the polishing belt 3 and to suppress the consumption of the abrasive grains 32 at the edge portion.

次に、実施例について説明する。まず、本出願人は、実施例として、図１に示す３段の研磨スタンド２に図２に示す研磨ベルト３（粒状弾性体：コルク、砥粒：ＳｉＣ）を取付けて、素材がＳＵＳ４０９、板厚が３．５ｍｍ、板幅が１２５２ｍｍ、全長が４５０ｍの鋼帯１に対して表面スケール除去を行った。また、本出願人は、比較例として、図３に示すような従来構成の研磨ベルト９を各段の研磨スタンド２に取付けて、同じ構成の鋼帯１に対して表面スケール除去を行った。なお、砥粒９１としてはＳｉＣ砥粒を使用した。   Next, examples will be described. First, as an example, the present applicant attaches the polishing belt 3 (granular elastic body: cork, abrasive grains: SiC) shown in FIG. 2 to the three-stage polishing stand 2 shown in FIG. The surface scale was removed from the steel strip 1 having a thickness of 3.5 mm, a plate width of 1252 mm, and a total length of 450 m. Further, as a comparative example, the present applicant attached a polishing belt 9 having a conventional configuration as shown in FIG. 3 to the polishing stand 2 of each stage, and performed surface scale removal on the steel strip 1 having the same configuration. Note that SiC abrasive grains were used as the abrasive grains 91.

このような表面スケール除去を行ったところ、本実施の形態の研磨ベルト３では、鋼帯１の全長に渡って表面スケールを除去できたのに対して、従来構成の研磨ベルト９では、１５０ｍ程度の表面スケール除去を行った時点で表面スケールの除去が不十分になった。すなわち、この実施例から、本実施の形態の研磨ベルト３の寿命が、従来構成の研磨ベルト９の寿命に比べて長くなっていることが確認できた。   When such surface scale removal was performed, the polishing belt 3 of the present embodiment was able to remove the surface scale over the entire length of the steel strip 1, whereas the conventional polishing belt 9 was about 150 m. When the surface scale was removed, the removal of the surface scale was insufficient. That is, it was confirmed from this example that the life of the polishing belt 3 of the present embodiment is longer than the life of the polishing belt 9 of the conventional configuration.

なお、本実施の形態の研磨ベルト３を用いての４５０ｍの表面スケール除去を行った後に、各段の研磨スタンド２に取付けられている研磨ベルト３の状態を確認した。その結果、１段目の研磨スタンド２（ライン方向１ａに沿う最も入側のスタンド）の研磨ベルト３は、目詰まりにより継続使用が困難な状態となっていが、後段の研磨スタンド２の研磨ベルト３は、継続使用に耐え得る状態であった。１段目の研磨スタンド２の研磨ベルト３を４５０ｍ毎に新品に交換して、同じ構成の鋼帯１に対して表面スケール除去を行ったところ、２段目及び３段目の研磨スタンド２の研磨ベルト３は１３５０ｍまで継続使用できた。このように後段の研磨ベルト３がより長く継続使用できるのは、１段目の研磨スタンド２において多量のスケールが除去されて、後段では１段目で取り切れなかったスケールを除去するだけだからと考えられる。すなわち、全ての研磨スタンド２の研磨ベルト３を一斉に交換する必要はなく、１段目の研磨ベルト３を適宜交換すれば、後段の研磨ベルト３はより長く使用できる。   In addition, after performing 450 m of surface scale removal using the polishing belt 3 of this Embodiment, the state of the polishing belt 3 attached to the polishing stand 2 of each step was confirmed. As a result, the polishing belt 3 of the first-stage polishing stand 2 (the most entering stand along the line direction 1a) is in a state where continuous use is difficult due to clogging, but the polishing belt of the subsequent-stage polishing stand 2 3 was a state that could withstand continuous use. When the polishing belt 3 of the first-stage polishing stand 2 was replaced with a new one every 450 m and the surface scale was removed from the steel strip 1 having the same configuration, the second-stage and third-stage polishing stands 2 The polishing belt 3 could be continuously used up to 1350 m. The reason why the subsequent stage polishing belt 3 can be used continuously for a long time is that a large amount of scale is removed in the first stage polishing stand 2 and only the scale that cannot be removed in the first stage is removed in the subsequent stage. Conceivable. That is, it is not necessary to replace the polishing belts 3 of all the polishing stands 2 at the same time, and if the first polishing belt 3 is appropriately replaced, the subsequent polishing belt 3 can be used longer.

このような表面スケール除去用の研磨ベルト３、及びそれを用いた鋼帯製造方法によれば、熱間圧延が終了された後の鋼帯１に対して、ベルト本体３０表面に設けられた複数の粒状弾性体３１の外面に付着されている砥粒３２が摺接されるので、砥粒３２間に詰った表面スケールを粒状弾性体３１の振動により除去できるとともに、鋼帯１のエッジ部分における砥粒３２への負荷を粒状弾性体３１の弾性により吸収できる。これにより、研磨ベルト３の目詰まりを起こしにくくすることができるとともに、エッジ部分における砥粒３２の消耗を抑えることができ、研磨ベルト３の寿命を長くできる。   According to the polishing belt 3 for removing the surface scale and the steel strip manufacturing method using the same, a plurality of belt belts 30 provided on the surface of the belt body 30 after the hot rolling is finished. Since the abrasive grains 32 attached to the outer surface of the granular elastic body 31 are brought into sliding contact with each other, the surface scale clogged between the abrasive grains 32 can be removed by the vibration of the granular elastic body 31, and at the edge portion of the steel strip 1. The load on the abrasive grains 32 can be absorbed by the elasticity of the granular elastic body 31. As a result, clogging of the polishing belt 3 can be made difficult to occur, wear of the abrasive grains 32 at the edge portion can be suppressed, and the life of the polishing belt 3 can be extended.

なお、実施の形態では、粒状弾性体３１が接着剤３３によりベルト本体３０に接着されるように説明しているが、ベルト本体が粒状弾性体と同じ素材により構成される場合には、ベルト本体が粒状弾性体と一体に設けられてもよい。   In the embodiment, it is described that the granular elastic body 31 is bonded to the belt main body 30 by the adhesive 33. However, when the belt main body is made of the same material as the granular elastic body, the belt main body May be provided integrally with the granular elastic body.
