Description

本発明は双ロール鋳造機に用いる冷却ロール清掃装置に関するものである。   The present invention relates to a cooling roll cleaning device used in a twin roll casting machine.

溶湯からストリップを直接的に生産する手法として、水平に並べた一対のロールの間に溶湯を供給し、凝固した金属を薄帯状に送り出す双ロール連続鋳造法がある。   As a method for directly producing a strip from a molten metal, there is a twin-roll continuous casting method in which the molten metal is supplied between a pair of horizontally arranged rolls and the solidified metal is fed into a thin strip shape.

図５、図６は従来の冷却ロール清掃装置の一例を装備した双ロール鋳造機を示すものであって、水平に並べて配置した一対の冷却ロール１と、当該冷却ロール１に付帯する一対のサイド堰２とを備えている。   5 and 6 show a twin-roll casting machine equipped with an example of a conventional cooling roll cleaning device, which includes a pair of cooling rolls 1 arranged horizontally and a pair of sides attached to the cooling roll 1. And a weir 2.

冷却ロール１は、その内部に冷却水が流通し、生産すべき鋼ストリップ３の板厚に応じてロール間隙Ｇを拡縮調整できるように構成されている。   The cooling roll 1 is configured so that cooling water flows through the roll 1 and the roll gap G can be adjusted in accordance with the thickness of the steel strip 3 to be produced.

冷却ロール１の回動方向及び速度は、各冷却ロール１の外周面が上側からロール間隙Ｇへ向かって等速で移動するように設定してある。   The rotation direction and speed of the cooling roll 1 are set so that the outer peripheral surface of each cooling roll 1 moves from the upper side toward the roll gap G at a constant speed.

一方のサイド堰２は、各冷却ロール１の一端に面接触し、他方のサイド堰２は、各冷却ロール１の他端に面接触している。   One side weir 2 is in surface contact with one end of each cooling roll 1, and the other side weir 2 is in surface contact with the other end of each cooling roll 1.

一対のサイド堰２の間には、溶湯供給ノズル４がロール間隙Ｇの真上に位置するように配置してあり、レードル（図示せず）から溶湯供給ノズル４へ溶鋼を注ぎ、冷却ロール１とサイド堰２で四方を囲まれる空間へ溶鋼を供給すると溶湯溜まり５が形成される。   A molten metal supply nozzle 4 is arranged between the pair of side weirs 2 so as to be located immediately above the roll gap G. The molten steel is poured from a ladle (not shown) to the molten metal supply nozzle 4, and the cooling roll 1 When molten steel is supplied to a space surrounded on all sides by the side weir 2, a molten metal pool 5 is formed.

つまり、上記の溶湯溜まり５を形成させるとともに、冷却水の流通により冷却ロール１を抜熱しながら回動させると、溶鋼が冷却ロール１の外周面で凝固し、各冷却ロール１の外周面に形作られた凝固殻６が張り合わされ、ロール間隙Ｇの下方へと鋼ストリップ３が送り出される。   That is, when the molten metal pool 5 is formed and the cooling roll 1 is rotated while removing heat by circulation of the cooling water, the molten steel is solidified on the outer peripheral surface of the cooling roll 1 and formed on the outer peripheral surface of each cooling roll 1. The solidified shells 6 are stuck together, and the steel strip 3 is sent out below the roll gap G.

このとき、鋼ストリップ３の板厚が目標値となるように、各冷却ロール１のネック部分を枢支している軸箱（図示せず）に、互いに近接する向きへ押し付ける力を与える。   At this time, a force is applied to a shaft box (not shown) pivotally supporting the neck portion of each cooling roll 1 in a direction approaching each other so that the plate thickness of the steel strip 3 becomes a target value.

操業時間の積み重ねに伴って、冷却ロール１の外周面にはマンガンや珪素などを含んだ酸化物が付着するが、これらの酸化物の付着層の厚みが増すと溶鋼から冷却ロール１への熱伝達の妨げとなり、冷却ロール１の外周面での凝固殻６の生成が抑えられてしまう。   As the operating time accumulates, oxides containing manganese, silicon, and the like adhere to the outer peripheral surface of the cooling roll 1, and heat from the molten steel to the cooling roll 1 increases as the thickness of the adhesion layer of these oxides increases. Transmission is hindered, and generation of the solidified shell 6 on the outer peripheral surface of the cooling roll 1 is suppressed.

そこで、冷却ロール１ごとに外周面軸線方向全長にわたって当接する円柱状のブラシ７を配置し、当該ブラシ７をモータ（図示せず）により冷却ロール１と同方向に回転させて冷却ロール１の外周面の研掃を実行し、酸化物の付着層を取り除くという手立てを採っている（例えば、特許文献１、２参照）。   Therefore, a columnar brush 7 that is in contact with the entire length of the outer peripheral surface in the axial direction is disposed for each cooling roll 1, and the brush 7 is rotated in the same direction as the cooling roll 1 by a motor (not shown). A method is adopted in which surface cleaning is performed to remove the oxide adhesion layer (see, for example, Patent Documents 1 and 2).

各ブラシ７の冷却ロール１に相対していない部位は、カウリング８によって個別に覆われている。   The portions of each brush 7 not facing the cooling roll 1 are individually covered by cowlings 8.

そして、各カウリング８に冷却ロール１の軸線方向に並ぶ複数のダスト吸引口９を対称に設け、排気ブロワ１０にダスト吸引口９を接続して、研掃に伴うダストの飛散を防いでいる。
特開平８−３０９４８８号公報 特開２０００−６４４号公報 A plurality of dust suction ports 9 arranged in the axial direction of the cooling roll 1 are provided symmetrically in each cowling 8, and the dust suction ports 9 are connected to the exhaust blower 10 to prevent dust from being scattered due to the blasting.
JP-A-8-309488 JP 2000-644

ブラシ７は、胴部１１の外周面の全般にわたり研掃用の素線群１２を植え付けたものであるが、高密度で植え付けられている素線群１２に入り込んだダストをカウリング８外部へ吸引することは容易ではない。   The brush 7 is formed by planting the wire group 12 for polishing over the entire outer peripheral surface of the body 11, and sucks dust that has entered the wire group 12 planted at high density to the outside of the cowling 8. It is not easy to do.

冷却ロール１の外周面を軸線方向全長にわたって研掃するブラシ７の清浄度に注目してみたところ、ブラシ７を構成している素線や胴部に残るダストは、ダスト吸引口９付近の範囲αではあまり認められないが、ダスト吸引口９から離れるほど多くなる。   When attention is paid to the cleanliness of the brush 7 that cleans the outer peripheral surface of the cooling roll 1 over the entire length in the axial direction, the wire constituting the brush 7 and the dust remaining on the body portion are in the vicinity of the dust suction port 9. Although it is not recognized so much at α, it increases as the distance from the dust suction port 9 increases.

このブラシ７の清浄度は冷却ロール１に反映され、当該ブラシ７のダスト吸引口９から離れた部位に多く残ったダストの一部が冷却ロール１の外周面へと移ることによって溶鋼から冷却ロール１への熱伝達の妨げとなる。   The cleanliness of the brush 7 is reflected on the cooling roll 1, and a part of the dust remaining in a portion away from the dust suction port 9 of the brush 7 moves to the outer peripheral surface of the cooling roll 1, thereby moving the cooling roll from the molten steel. The heat transfer to 1 is hindered.

すなわち、冷却ロール１の外周面において、ブラシ７のダスト吸引口９付近の範囲αが当接する部位では凝固殻６の生成が順調に進むが、他の部位ではダストが熱伝達の妨げとなることに起因して凝固殻６の生成が捗らない。   That is, on the outer peripheral surface of the cooling roll 1, the generation of the solidified shell 6 proceeds smoothly at the portion where the range α in the vicinity of the dust suction port 9 of the brush 7 contacts, but the dust interferes with heat transfer at other portions. Due to this, the formation of the solidified shell 6 does not progress.

よって、一対の冷却ロール１が送出する鋼ストリップ３は、図６に示す凝固殻６の生成が順調に進んだ山部分を互いに張り合わせた状態となるものの、冷却ロール１の軸線方向に並ぶ山部分の間の谷部分には未凝固領域が残ることになる。   Therefore, the steel strip 3 delivered by the pair of cooling rolls 1 is in a state in which the mountain portions where the generation of the solidified shell 6 shown in FIG. An unsolidified region remains in the valley portion between.

更に、凝固による縮小が完了した後の鋼ストリップ３では、板幅方向厚み分布がむらになり、割れが生じることもある。   Furthermore, in the steel strip 3 after the reduction by solidification is completed, the thickness distribution in the plate width direction becomes uneven, and cracks may occur.

本発明は上述した実情に鑑みてなしたもので、ブラシの清浄度を高く保てる冷却ロール清掃装置を提供することを目的としている。   The present invention has been made in view of the above-described circumstances, and an object of the present invention is to provide a cooling roll cleaning device that can keep the cleanness of a brush high.

上記目的を達成するため、本発明の冷却ロール清掃装置は、外周面から内方へ貫通する多数の吸引孔が穿設され且つ冷却ロール軸線に対して平行に延びる自転可能な筒状の胴部と、この胴部の外周面に植え付けられ且つ胴部の回転により先端が冷却ロール外周面に当接する研掃用の素線群と、前記胴部の一端に設けられ且つ胴部内の空間に連通するダスト吸引口とを有するブラシを備え、前記ダスト吸引口に排気機構を接続している。   In order to achieve the above object, the cooling roll cleaning device of the present invention is a cylindrical body portion that is capable of rotation and has a plurality of suction holes penetrating inward from the outer peripheral surface and extending parallel to the cooling roll axis. A group of strands for polishing which are planted on the outer peripheral surface of the body and whose tip is brought into contact with the outer surface of the cooling roll by rotation of the body, and communicates with a space in the body provided at one end of the body And a brush having a dust suction port, and an exhaust mechanism is connected to the dust suction port.

具体的には研掃用の素線群を、胴部の外周面に胴部一端から他端へ向かう螺旋状の列を形作るように植え付ける。   Specifically, the strands for scouring are planted on the outer peripheral surface of the barrel so as to form a spiral line from one end of the barrel to the other end.

あるいは、研掃用の素線群を、胴部の外周面に胴部一端から他端へ向けて複数条の列をなすように植え付ける。   Alternatively, the strands for scouring are planted on the outer peripheral surface of the trunk so as to form a plurality of rows from one end of the trunk toward the other end.

また、列ごとに素線群の毛丈、線径、もしくは材質を変えた構成、ブラシの冷却ロールに相対していない部位をカウリングで覆った構成も選べる。   Moreover, the structure which changed the bristle length, wire diameter, or material of the strand group for every row | line | column, and the structure which covered the site | part which is not opposed to the cooling roll of a brush with the cowling can also be selected.

本発明の冷却ロール清掃装置によれば、下記のような優れた効果を奏し得る。   According to the cooling roll cleaning apparatus of the present invention, the following excellent effects can be obtained.

（１）外周面に素線が植え付けられる胴部に多数の吸引孔を穿設したので、研掃に伴うダストは吸引孔から胴部内の空間に入り、ダスト吸引口を経て排出され、ブラシの清浄度を高く保てる。   (1) Since a large number of suction holes are drilled in the body part where the strands are planted on the outer peripheral surface, dust accompanying the cleaning enters the space in the body part from the suction hole, is discharged through the dust suction port, The cleanliness can be kept high.

（２）胴部の外周面に素線群を、胴部一端から他端へ向かう螺旋状の列を形作るように植え付けた構成、あるいは、胴部の外周面に素線群を、胴部一端から他端へ向けて複数条の列をなすように植え付けた構成を採れば、多数の素線が同時に冷却ロール外周面に当接する範囲が狭まるので、冷却ロールに向けてブラシを大きな力で押し付けなくても、冷却ロールに対する素線群の接触面圧を確保でき、酸化物付着層を冷却ロール外周面から確実に取り除ける。   (2) A configuration in which the strands are planted on the outer peripheral surface of the trunk portion so as to form a spiral line from one end of the trunk portion to the other end, or the strand group is placed on one end of the trunk portion. By adopting a configuration in which a plurality of rows are planted from one end to the other, the range in which many strands simultaneously contact the outer peripheral surface of the cooling roll is narrowed, so the brush is pressed toward the cooling roll with a large force. Even if it does not exist, the contact surface pressure of the strand group with respect to a cooling roll can be ensured, and an oxide adhesion layer can be reliably removed from a cooling roll outer peripheral surface.

（３）よって、冷却ロールが送出するストリップの板幅方向厚み分布がむらにならずに平均化される傾向を呈し、割れの発生を回避できる。   (3) Therefore, the thickness distribution in the plate width direction of the strip sent by the cooling roll tends to be averaged without being uneven, and the occurrence of cracks can be avoided.

以下、本発明の実施の形態を図面に基づき説明する。   Hereinafter, embodiments of the present invention will be described with reference to the drawings.

図１、図２は本発明の冷却ロール清掃装置の一例を装備した双ロール鋳造機を示すもので、図中、図５、図６と同一の符号を付した部分は同一物を表している。   1 and 2 show a twin-roll casting machine equipped with an example of the cooling roll cleaning device of the present invention. In the figure, the same reference numerals as those in FIGS. 5 and 6 denote the same parts. .

この冷却ロール清掃装置では、冷却ロール１ごとに配置したブラシ１３をモータ（図示せず）により冷却ロール１と同方向に回転させて冷却ロール１の外周面の研掃を実行し、酸化物の付着層を取り除くという手立てを採っている。   In this cooling roll cleaning device, the brush 13 disposed for each cooling roll 1 is rotated in the same direction as the cooling roll 1 by a motor (not shown), and the outer peripheral surface of the cooling roll 1 is cleaned. The measures are taken to remove the adhesion layer.

ブラシ１３は、外周面から内方へ貫通する多数の吸引孔１４が穿設してある筒状の胴部１５と、この胴部１５の外周面に胴部１５一端から他端へ向かう螺旋状の列を形作るように植え付けた研掃用の素線群１６と、前記胴部１５の一端に嵌まるリングプレート１７を介して胴部１５に同軸に組み付けた中空軸状のダスト吸引口１８と、前記胴部１５の他端に嵌まるプレート（図示せず）を介して胴部１５に同軸に取り付けた支持軸１９と有し、冷却ロール１の軸線に対して平行に、しかも胴部１５の回転により素線群１６の先端が順に冷却ロール１の外周面に当接するように配置されている。   The brush 13 has a cylindrical body portion 15 having a large number of suction holes 14 penetrating inward from the outer peripheral surface, and a spiral shape extending from one end of the body portion 15 to the other end on the outer peripheral surface of the body portion 15. A group of strands 16 for scouring planted so as to form a row, and a hollow shaft-shaped dust suction port 18 coaxially assembled to the body 15 via a ring plate 17 fitted to one end of the body 15 And a support shaft 19 that is coaxially attached to the body 15 via a plate (not shown) that is fitted to the other end of the body 15, parallel to the axis of the cooling roll 1, and the body 15 Is arranged so that the tip end of the strand group 16 contacts the outer peripheral surface of the cooling roll 1 in order.

上記の「…螺旋状の列を形作るように植え付けた研掃用の素線群１６」という記述は、胴部１５に穿設した植込用の孔に所定本数の素線の束を植え付ける手法、もしくは、所定の厚みを持つように素線群を溝形の長尺ホルダで拘束したチャンネルブラシを胴部１５に取り付ける手法のいずれをも包含している。   The above-mentioned description “… the strands 16 for polishing that are planted so as to form a spiral row” is a method of planting a bundle of a predetermined number of strands in a hole for implantation bored in the body portion 15. Alternatively, any of the methods of attaching a channel brush, in which a strand group is constrained by a groove-shaped long holder so as to have a predetermined thickness, to the body portion 15 is included.

各ブラシ１３の冷却ロール１に相対していない部位は、カウリング２０によって個別に覆われている。   The portions of each brush 13 that are not opposed to the cooling roll 1 are individually covered by the cowling 20.

胴部１５内の空間に連通する中空軸状のダスト吸引口１８に、ブラシ１３の回転を許容するロータリジョイント（図示せず）、及び配管２１を介して強制的に排気を行う排気機構としての排気ブロワ１０を接続し、研掃に伴うダストの飛散を防いでいる。   As an exhaust mechanism that forcibly exhausts air through a rotary joint (not shown) that allows rotation of the brush 13 and a pipe 21 to a hollow shaft-shaped dust suction port 18 that communicates with the space in the body portion 15. An exhaust blower 10 is connected to prevent dust from being scattered due to scouring.

双ロール鋳造機の操業に際しては、ブラシ１３をモータ（図示せず）により冷却ロール１と同方向に回転させて冷却ロール１の外周面の研掃を行い、酸化物の付着層を取り除くとともに、排気ブロワ１０を作動させて各カウリング２０の内部のダストを捕集する。   During operation of the twin roll casting machine, the brush 13 is rotated in the same direction as the cooling roll 1 by a motor (not shown) to clean the outer peripheral surface of the cooling roll 1 to remove the oxide adhesion layer, The exhaust blower 10 is operated to collect dust inside each cowling 20.

胴部１５の外周面に素線群１６を、胴部１５一端から他端へ向かう螺旋状の列を形作るように植え付けてあるので、素線群１６が同時に冷却ロール１の外周面に当接する範囲が狭く、冷却ロール１の外周面の幅方向プロファイルがブラシ１３に直接的な影響を及ぼすことがなく、冷却ロール１に向けてブラシ１３を特に大きな力で押し付けなくても、冷却ロール１に対する素線群１６の接触面圧を確保でき、これにより、酸化物の付着層を冷却ロール１の外周面から確実に取り除ける。また、ブラシ１３の押し付け力を小さくできるので、ブラシ１３を冷却ロール１に押し付けるための機構（押し付けシリンダ等）の小型化、ブラシ１３を回転させるための機構に要する駆動エネルギの削減等を図ることができる。   Since the strand group 16 is planted on the outer peripheral surface of the trunk portion 15 so as to form a spiral line from one end of the trunk portion 15 to the other end, the strand group 16 simultaneously contacts the outer circumferential surface of the cooling roll 1. The range is narrow, the width direction profile of the outer peripheral surface of the cooling roll 1 does not directly affect the brush 13, and even if the brush 13 is not pressed against the cooling roll 1 with a particularly large force, The contact surface pressure of the strand group 16 can be ensured, whereby the oxide adhesion layer can be reliably removed from the outer peripheral surface of the cooling roll 1. In addition, since the pressing force of the brush 13 can be reduced, a mechanism for pressing the brush 13 against the cooling roll 1 (such as a pressing cylinder) can be downsized, and driving energy required for the mechanism for rotating the brush 13 can be reduced. Can do.

しかも、研掃に伴うダストは、多数の吸引孔１４から胴部１５内の空間に入り、ダスト吸引口１８を経てカウリング２０の外部へ直ちに排出され、素線群１６の植え付け密度も低いので、当該素線群１６にダストが極めて入り難く、ブラシ１３の清浄度を高く保てることになる。すなわち、素線群１６内にダストが入り込んだり、胴部１５の表面にダストが付着したりしても、これらのダストを吸引孔１４によって素早く確実に吸引し、胴部１５から排出できる。なお、カウリング２０によってブラシ１３を覆うことで、ダストがブラシ１３の周囲に飛散することを好適に防止できる。また、ブラシ１３の近傍（カウリング２０の内側）を周囲（カウリング２０の外側）に対して負圧にしやすく、排気ブロワ１０の作動によるダストの回収を効率的に行うことができる。   In addition, the dust accompanying the scouring enters the space in the body portion 15 from the many suction holes 14, is immediately discharged to the outside of the cowling 20 through the dust suction port 18, and the planting density of the strand group 16 is low. Dust is extremely difficult to enter the wire group 16 and the cleanliness of the brush 13 can be kept high. That is, even if dust enters the wire group 16 or dust adheres to the surface of the trunk portion 15, these dusts can be quickly and reliably sucked through the suction hole 14 and discharged from the trunk portion 15. In addition, it can prevent suitably that dust scatters around the brush 13 by covering the brush 13 with the cowling 20. Also, the vicinity of the brush 13 (inside the cowling 20) can be easily made negative with respect to the surroundings (outside of the cowling 20), and dust can be collected efficiently by the operation of the exhaust blower 10.

よって、冷却ロール１の外周面での凝固殻６（図６参照）の生成が捗り、冷却ロール１が送出する鋼ストリップ３の板幅方向厚み分布がむらにならずに平均化される傾向を呈し、割れの発生を回避できる。   Therefore, the generation of the solidified shell 6 (see FIG. 6) on the outer peripheral surface of the cooling roll 1 progresses, and the thickness distribution in the plate width direction of the steel strip 3 delivered by the cooling roll 1 tends to be averaged without being uneven. Present and avoid the occurrence of cracks.

図３はブラシ１３の変形例であり、素線群１６による螺旋状の列とは別途に、胴部１５の外周面に胴部１５一端から他端へ向かう螺旋状の列を形作るように研掃用の素線群２２を植え付けて、螺旋状の列を二条としている。   FIG. 3 shows a modified example of the brush 13. In addition to the spiral rows formed by the strands 16, the brush 15 is sharpened so as to form a spiral row from one end of the body portion 15 toward the other end on the outer peripheral surface of the body portion 15. A group of sweeping strands 22 is planted to form two spiral rows.

素線群１６，２２は、同一種として研掃効果を揃えてもよいが、列ごとに素線群１６，２２の毛丈（胴部１５の外周面から素線先端までの長さ）、線径、材質などを変えれば、異なった研掃効果が得られる。   The strand groups 16 and 22 may have the same cleaning effect as the same species, but the hair length of the strand groups 16 and 22 (the length from the outer peripheral surface of the body 15 to the tip of the strand) for each row, If the wire diameter, material, etc. are changed, different cleaning effects can be obtained.

図４はブラシ１３の他の変形例であり、胴部１５の外周面に胴部１５一端から他端へ向けて複数条の列をなすように、研掃用の素線群２３を胴部１５周方向に等間隔に植え付けている。   FIG. 4 shows another modified example of the brush 13, and the strands 23 for scouring are arranged on the outer peripheral surface of the barrel 15 so that a plurality of rows are formed from one end to the other end of the barrel 15. It is planted at equal intervals in the 15-round direction.

各素線群２３は、胴部１５の軸線に対して斜めに延びており、胴部１５の一端と他端とでは、植え付け位置が胴部１５周方向にずれているので、素線群２３が同時に冷却ロール１（図１参照）の外周面に当接する範囲が狭く、冷却ロール１の外周面の幅方向プロファイルがブラシ１３に直接的な影響を及ぼすことがなく、冷却ロール１に向けてブラシ１３を特に大きな力で押し付けなくても、冷却ロール１に対する素線群２３の接触面圧を確保でき、これにより、酸化物の付着層を冷却ロール１の外周面から確実に取り除ける。   Each strand group 23 extends obliquely with respect to the axis of the trunk portion 15, and the planting position is shifted in the circumferential direction of the trunk portion 15 at one end and the other end of the trunk portion 15. Are simultaneously in contact with the outer peripheral surface of the cooling roll 1 (see FIG. 1), and the profile in the width direction of the outer peripheral surface of the cooling roll 1 does not directly affect the brush 13, and is directed toward the cooling roll 1. Even if the brush 13 is not pressed with a particularly large force, the contact surface pressure of the wire group 23 with respect to the cooling roll 1 can be ensured, whereby the oxide adhesion layer can be reliably removed from the outer peripheral surface of the cooling roll 1.

しかも、研掃に伴うダストは、多数の吸引孔１４から胴部１５内の空間に入り、ダスト吸引口１８を経てカウリング２０（図１参照）の外部へ直ちに排出され、素線群２３の植え付け密度も低いので、当該素線群２３にダストが極めて入り難く、ブラシ１３の清浄度を高く保てることになる。すなわち、素線群２３にダストが入り込んだり、胴部１５の表面にダストが付着したりしても、これらのダストを吸引孔１４によって素早く確実に吸引し、胴部１５から排出できる。   In addition, the dust accompanying the cleaning enters the space in the body portion 15 through the numerous suction holes 14, is immediately discharged to the outside of the cowling 20 (see FIG. 1) through the dust suction port 18, and the strand group 23 is planted. Since the density is also low, dust hardly enters the strand group 23, and the cleanliness of the brush 13 can be kept high. That is, even if dust enters the wire group 23 or dust adheres to the surface of the trunk portion 15, these dusts can be quickly and reliably sucked through the suction hole 14 and discharged from the trunk portion 15.

また、以上の実施形態では、ダストを吸引する吸引孔を胴部１５にのみ設けた構成としたが、カウリング２０にも吸引孔を備えても良い。すなわち、ブラシ１３付近のダストを、胴部１５の吸引孔によっても、カウリング２０の吸引孔によっても吸引できるようにしても良い。そうすれば、ダストの捕集をより確実に行いやすくなる。素線群１６，２２の列の巻き方向は、右ねじ状であっても左ねじ状であっても良い。ブラシ１３自体の回転方向も限定されない。   Further, in the above embodiment, the suction hole for sucking dust is provided only in the body portion 15, but the cowling 20 may be provided with a suction hole. That is, the dust near the brush 13 may be sucked by the suction hole of the body portion 15 or the suction hole of the cowling 20. This makes it easier to collect dust more reliably. The winding direction of the strands 16 and 22 may be right-handed or left-handed. The rotation direction of the brush 13 itself is not limited.

なお、本発明の冷却ロール清掃装置は、上述した実施の形態のみに限定されるものではなく、本発明の要旨を逸脱しない範囲において変更を加え得ることは勿論である。   In addition, the cooling roll cleaning apparatus of this invention is not limited only to embodiment mentioned above, Of course, it can add a change in the range which does not deviate from the summary of this invention.

本発明の冷却ロール清掃装置は、鋼以外の金属を原料にストリップを製造する双ロール鋳造機にも適用することができる。   The cooling roll cleaning apparatus of the present invention can also be applied to a twin roll casting machine that manufactures a strip using a metal other than steel as a raw material.
