【発明の詳細な説明】 [産業上の利用分野] この発明は、冷却床への条鋼搬入トラフまたは搬入ローラーテーブル入口で圧延材にトラブルが発生した時、トラブルを自動的に検知し、圧延材をコブルカッティングして圧延機への圧延材の噛込みを中断してミスロールの発生量を低減させる条鋼の圧延方法に関する。 DETAILED DESCRIPTION OF THE INVENTION [Field of the Industrial] This invention, when a trouble occurs in the rolled material in long products carrying trough or carrying roller table entrance to the cooling bed, automatically detect problems, rolled material the related rolling method of long steel to reduce the generation amount of Misuroru to interrupt inclusive bite of the rolled material to Cobble cutting to mill.

[従来技術] 条鋼の圧延は、通常第5図のような設備配置にて行なわれる。 Rolling PRIOR ART long products is carried out in a usual equipment arrangement shown in Figure 5. すなわち、条鋼圧延用のビレットは、加熱炉21で加熱される。 That is, the billet for long product rolling is heated in a heating furnace 21. そして、加熱されたビレットは、粗圧延機 The heated billets, roughing mill
22、中間圧延機23および仕上圧延機24の順に圧延されて最終製品の断面形状となる。 22, is rolled in the order of the intermediate mill 23 and the finishing mill 24 with the final product of the cross-sectional shape. 次いで仕上圧延機24の後方に配置した分割シヤー25で100m程度の長さごとに切断された後、冷却床26に搬入される。 Then, after being cut for each length of about 100m in a split shear 25 provided behind the finishing mill 24, it is carried into the cooling bed 26. 冷却床26において前記切断された長尺条鋼27は、レッヘン28により冷却床26の出口方向に移送され、アラインメントローラ29により長さ方向に送られて、ストッパ30に衝突させられ、長尺条鋼27の先端が揃えられる。 Long long steel 27 which is the cutting in the cooling bed 26 is transported in the exit direction of the cooling bed 26 by Rehhen 28, is sent in the longitudinal direction by the alignment roller 29 are brought into collision with the stopper 30, the long steel bars 27 the tip of the are aligned. そして、冷却床26の搬出口に設けたドライブローラ31により、長尺条鋼27は5〜100 Then, by the drive roller 31 provided on the carry-out port of the cooling bed 26, the long steel bars 27 5-100
本毎に冷却床26から搬出され、コールドシヤー32によりまとめて切断され、長さの揃った短尺条鋼33となる。 Is carried out to each present a cooling bed 26, they are collectively cut by Korudoshiya 32, a short long steel 33 with uniform length. なお、粗圧延機22、中間圧延機23および仕上圧延機24の間には、コブル切断用のフライングシヤー34を設けて、トラブル発生時にコブルカッティングを行ない、圧延材の圧延機への噛込みを中断して、大量のミスロール材が発生しないようにしている。 Incidentally, rough rolling mill 22, between the intermediate mill 23 and finishing mill 24, provided with a flying shear 34 for Cobble cutting performs Cobble cutting when trouble occurs, the biting of the rolling mill of the rolled material is interrupted, a large amount of Misuroru material is not to occur.

ところで、冷却床26の入口には条鋼を冷却床26に搬入するための搬入テーブルまたは搬入トラフ35が設けられいるが、搬入トラフ35を設けている設備においては、条鋼は自動的に複数の搬入トラフ35に振り分けられて、搬入トラフ35内を進み全長が搬入トラフ35内に納まったタイミングで搬入トラフ35の回転軸が回転し、搬入トラフ35 By the way, carrying the table or loading trough 35 for carrying the long products to cooling beds 26 to the inlet of the cooling bed 26 is provided in the equipment is provided with a loading trough 35, long products are automatically plurality of loading It is distributed to the trough 35, to rotate the rotary shaft of the loading trough 35 at the timing when the full-length advances the loading trough 35 is accommodated in the loading trough 35, loading trough 35
内の長尺条鋼27は搬入トラフ35から落下し、冷却床26に設けたレッヘン28により冷却床26に搬入されるようになっている。 Long long products 27 of the inner will fall from the loading trough 35 is adapted to be carried into the cooling bed 26 by Rehhen 28 provided in the cooling bed 26. また、搬入テーブルは傾斜した多数のローラーからなり、比較的低速度で搬入される条鋼の場合に使用される。 Also, carry-table consists of a number of rollers which are inclined, are used in the case of long steel being transported at a relatively low speed.

[発明が解決しようとする課題] 上記した搬入トラフ35に条鋼が突入するとき、長尺条鋼 When long products rushes to the carrying trough 35 as described above [0007], long long products
27の先端の切断面に切断時に発生した切断ばりが付着していると、この切断ばりが搬入トラフ35の縁に当たって、長尺条鋼27が搬入トラフ35にうまく導かれず、搬入トラフ35の前でくしゃくしゃに折れ曲がって後続の長尺条鋼27の進行を妨害することになり、圧延を中断しなければならない自体が発生することがある。 The cutting burrs generated during cutting are attached on the cut surface of the tip 27, when the edge of the cutting burr is carried trough 35, not guided well to long long products 27 conveyed trough 35, in front of the loading trough 35 crumpled the bent would interfere the progress of the subsequent long steel bars 27, itself must be interrupted rolling may occur.

上記したような状態が発生した場合、従来は作業員が目視でその状態を確認し、電話等で圧延機の運転者に連絡して、条鋼の圧延を中断するようにしていた。 When the state as described above occurs, conventional checks its state visually worker, contact the operator of the mill on the phone, etc., it had to be interrupted rolling long products. しかしながら、このような方法で圧延を中断するのでは、トラブルの発生から圧延を中断するまでに時間がかかりすぎ、 However, this way of aborting the rolling in a way, too much time from troubles occur before aborting the rolling,
その間中条鋼が圧延されしかもそのすべてが搬入トラフ前で折れ曲がってしまうので、ほとんどビレット1本分のスクラップが発生し、そのスクラップを除去するために30分もの時間を要するので、条鋼圧延の稼働率を著しく低下させるという問題点があった。 Since all the addition is between in long products are rolled will bent before carrying trough, almost billet one roll of scrap generated, it takes 30 minutes of time in order to remove the scrap, the operation rate of long product rolling was a problem that significantly reduces.

この発明は、従来技術の上述のような問題点を解消し、 This invention is to solve the aforementioned problems of the prior art,
搬入トラフ前でトラブルが発生したとき、自動的に異常を検出して圧延材をコブルカッティングして、圧延材の圧延機への噛込みを中断することにより、スクラップの発生を極力減少させる条鋼の圧延方法を提供することを目的としている。 When trouble occurs in the previous loading trough, automatically abnormality detection by the rolled material and Cobble cutting by the by interrupting biting into the rolling mill of the rolled material, of long products that reduce the occurrence of scrap utmost and its object is to provide a rolling method.

[課題を解決するための手段] この発明に係る条鋼の圧延方法は、条鋼圧延機群に後続する冷却床入口の搬入トラフまたは搬入ローラーテーブルの中間に圧延材検出装置を設け、圧延機群と冷却床の間に配置された走行分割シヤーからの切断信号が発せられてから所定の時間内に前記圧延材検出装置が圧延材を検出しない場合、圧延機群の間に設けたフライングシヤーにて圧延材をコブルカッティングして圧延機への圧延材の噛込みを中断する条鋼の圧延方法である。 [Means for Solving the Problems] rolling method of long products according to the invention, a rolled material detecting device provided in the middle of the cooling bed inlet of the loading trough or carrying roller table following the long products mill group, and the mill group If the rolled material detecting device disconnection signal from disposed in the cooling beds traveling divided shears from is issued within a predetermined time it does not detect the rolled material, the rolled material at a flying shears provided between the mill group which is a rolling method of interrupting long products a lump bite of the rolled material to the Cobble cutting to the rolling mill.

[作用] この発明に係る条鋼の圧延方法においては、条鋼圧延機群に後続する冷却床入口の搬入トラフまたは搬入ローラーテーブルの中間に圧延材検出装置を設け、圧延機群と冷却床の間に配置された走行分割シヤーからの切断信号が発せられてから所定の時間内に前記圧延材検出装置が圧延材を検出しない場合、圧延機群の間に設けたフライングシヤーにて圧延材をコブルカッティングして圧延機への圧延材の噛込みを中断するようにしている。 [Operation] In the rolling method of long products according to the invention is provided with a rolled material detecting apparatus in the middle of the cooling bed inlet of the loading trough or carrying roller table following the long products mill group are disposed in the cooling alcove and mill group and when the running dividing the rolled material detection device disconnected from the signal is issued within a predetermined time from the shear does not detect the rolled material, and Cobblestone cutting the rolled material at a flying shears provided between the mill group and so as to interrupt the biting of the strip into the rolling mill. このようにして圧延しているので、搬入トラフまたは搬入ローラーテーブルに条鋼がうまく導かれずにトラブルが発生した場合、圧延材検出装置は走行分割シヤーからの切断信号が発せられてから所定時間内に条鋼を検出できないので、これに基づく警報信号を圧延機運転室に送る。 Since the rolled this way, if trouble occurs without long products are directed well to carry trough or carrying roller table, the rolled material detection device within a predetermined from being issued is disconnect signal from the traveling dividing shears time can not detect long products, it sends an alarm signal based on this mill cab. この警報信号に基づき、圧延機の間に設けられているコブルカッティング用のフライングシヤーが自動的に作動して、圧延材のコブルカッティングを行ない、圧延機への圧延材の噛込みを中断させる。 Based on this alarm signal, the rolling mill a flying shears for Cobble cutting is provided is operated automatically during performs Cobble cutting of the rolled material, to interrupt the biting of the strip into the rolling mill. 前記圧延材検出装置は、 The rolled material detecting apparatus,
異常発生から短時間で異常を検出できるので、異常発生から圧延中断までの時間も短くなり、その間に発生するスクラップの発生量は少なくてすむ。 Because a short time can be detected abnormality from the abnormality occurs, is shortened time from the abnormality occurrence to the rolling interruptions, fewer generation amount of scrap generated therebetween. したがって、異常発生に伴うスクラップ除去作業も短時間で行なえるので圧延機の稼働率を高めることができる。 Therefore, it is possible to increase the operation rate of a rolling mill so performed in a short time even scrap removal operation accompanying the occurrence of abnormality. 合わせてスクラップの減少に伴い圧延歩留が向上する。 Rolling yield with decreasing scrap combined is improved.
