本発−明は高速走行中の帯鋼を起動停止式の走間ドラム
シャーによって切断する高速走間切断装置に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a high-speed running cutting device for cutting a steel strip running at high speed using a running drum shear of a start/stop type.

いる。In the figure, 01 is a hot finishing rolling mill group, 02 is a cooling device,
04 is a running drum shear, and the steel strip S that has been finally hot rolled by the hot finishing mill group 01 at a running speed of, for example, 500 ml-m is heated by the cooling device 02 to, for example, 6
The steel strip is cooled to 00° C. and wound into a steel strip coil SC by a first down coiler 09a via a deflector pinch roll 08a. When the steel strip coil Sc reaches a predetermined weight, a running drum shear 04 of a start/stop type is set such that the circumferential speed of the upper and lower knives 013, 014 attached to that surface is synchronized with the running speed of the steel strip S. The steel strip S is cut by rotating.

近年、熱間帯鋼圧延設備においては、帯鋼の走行を例え
ば１０００ ｍ／ｍ に高速化することによる生産性
の向上が要求されている。In recent years, in hot strip steel rolling equipment, there has been a demand for improved productivity by increasing the running speed of the strip to, for example, 1000 m/m.
ところが熱間帯鋼圧延設備の起動停止式の走間ドラムシ
ャーは、その設計上、回転速度の上限は５００ｍ１閣程
度である。However, due to its design, the upper limit of the rotational speed of the start/stop type running drum shear for hot strip steel rolling equipment is approximately 500 m1.
このため、従来のように前記走間ドラムシャーのナイフ

も帯鋼切断時に板振れを生ずる不具合がある。For this reason, the peripheral speed of the knife of the running drum shear was synchronized with the running speed of the steel strip as in the past.
The running speed of steel strip, which has been requested in recent years, has been increased to 1000 m/m.
It is impossible to achieve such high speeds, and it is difficult to improve productivity. Furthermore, even if the steel strip is cut by increasing the traveling speed of the strip to be higher than the maximum circumferential speed of the drum shear, there is a problem in that the strip runs out when cutting the strip.

切断可能に構成したことを特徴としている。In order to solve the above-mentioned problems, the high-speed running cutting device of the present invention cuts the strip steel rolled by a hot finishing mill and running at high speed. In a high-speed running cutting device that cuts with Pinch rolls are arranged, and when a predetermined weight of the steel strip coil around which the steel strip is wound reaches a predetermined weight, tension is applied to the steel strip between the two pinch rolls, and the tension is applied to the upper and lower knives attached to the outer peripheral surface of the running drum shear. The feature is that the steel strip can be cut by shearing force.

走間ドラムシャーのドラムの回転を停止する。The above-described high-speed running cutting device of the present invention increases the rotational speed of the outlet pinch roll disposed on the outlet side of the running drum shear when cutting steel strip, and When a tensile force is applied to the strip steel between the side pinch rolls and the drum of the running drum shear is rotated in this state, the shearing force due to the flywheel effect of the drum, the tensile force due to the output side pinch rolls, and the running drum When the shear starts cutting, the circumferential speed of the knife attached to the 0 circumferential surface of the drum shear is slower than the traveling speed of the high-speed steel strip (the knife applies a brake on the traveling of the steel strip). Can cut steel. At the end of this cut, before the knife rotates and contacts the trailing strip,
Stop the rotation of the drum of the running drum shear.

に搬送することができる。As described above, according to the high-speed running cutting device of the present invention,
Pinch rolls are installed on the entry and exit sides of the running drum shear, and when cutting the strip, the rotational speed of the exit pinch roll is increased to apply tension to the steel strip between it and the entry pinch roll. The steel strip can be cut by this tension, the shearing force due to the flywheel effect of the running drum shear, and the tension generated because the peripheral speed of the knife at the start of cutting is slower than the running speed of the steel strip, which is running at high speed. Therefore, even if a start/stop type running drum shear is used, which makes it difficult to increase the rotational speed, the running speed of the running cutting device can be made significantly higher than the upper limit rotational speed of the running drum shear. In addition, when cutting the steel strip, the input side pinch rolls prevent the tip of the following steel strip from swinging in the vertical direction, and the output side The tip of the trailing steel strip is prevented from swinging in the vertical direction by the Vinci roll, and the tip of the trailing steel strip is prevented by, for example, arranging a linear motor-type steel strip conveying device behind the exit Vinci roll. Coins can be transported reliably without contact with the front pinch rolls.
