置に搬送するＩＩｔ造となっていた。The conventional hot slab conveying device is disclosed in Japanese Patent Application No. 62-74106.
As described in the above issue, the width press equipment is equipped with a pair of upper and lower pinch rolls on the entry and exit sides respectively, and the hot slab is pressed by the upper and lower pinch rollers and transported to the press position of the width press equipment. It had become.
しかしながら、上記従来の装置では、熱間スラブの搬送
中にピンチロールが搬送方向に傾き、熱間スラブが幅方
向に傾き、熱間スラブを正確に幅プレス装置のプレス位
置に搬送できないという問題があった。However, with the above-mentioned conventional equipment, the pinch roll tilts in the transport direction while the hot slab is being transported, and the hot slab tilts in the width direction, making it impossible to accurately transport the hot slab to the pressing position of the width press device. there were.
また、熱間スラブの幅プレス中、ピンチロールの押さえ
部でプレスの衝撃振動により熱間スラブに傷付きが生じ
たり、その衝撃振動がピンチロールに伝わり、搬送装置
が早期に損傷するという問題があった。In addition, during the width pressing of hot slabs, the hot slabs are damaged by the impact vibration of the press at the pressing part of the pinch rolls, and the impact vibrations are transmitted to the pinch rolls, causing early damage to the conveying device. there were.
本発明の目的は、熱間スラブを傾けることなくプレス位
置へ正確に搬送できる熱間スラブ搬送装置を提供するこ
とである。An object of the present invention is to provide a hot slab conveying device that can accurately convey a hot slab to a press position without tilting the hot slab.
本発明の他の目的は、熱間スラブの傷付き防止と装置を
保護できる熱間スラブ搬送装置を提供することである。Another object of the present invention is to provide a hot slab conveying device that can prevent hot slabs from being damaged and protect the device.
上記目的は、熱間スラブの搬送中に前記ピンチロールを
熱間スラブ搬送方向及び反搬送方向のいずれか一方向に
押し、ピンチロールの振れを阻止する振れ止め手段を設
けることによって達成される。The above object is achieved by providing a steady rest means for pushing the pinch roll in either the hot slab transport direction or the anti-transfer direction during transport of the hot slab and preventing the pinch roll from swinging.
また、上記目的は、熱間スラブの幅プレス中は、前記ピ
ンチロールの熱間スラブ押付は力と前記振れ止め手段の
ピンチロール振れ止め力を解放することにより達成され
る。Moreover, the above object is achieved by releasing the hot slab pressing force of the pinch rolls and the steady resting force of the pinch rolls of the steady rest means during width pressing of the hot slab.

熱間スラブの正確な搬送が可能である。This will now be explained with reference to FIG. 4 in comparison with the conventional case. Conventionally, as shown in FIG. 4, the steady rest cylinders 8a and 8b of this embodiment were not provided.
Since there is a gap G between the bearing boxes 4a and 4b and the frame post 6a and entry side post 6b of the housing, the difference in reaction force during conveyance of the hot slab 1 causes the pinch roll 2a to
, 2b are tilted as shown in the figure. Therefore, the hot slab 1 is also conveyed in a tilted state in the width direction, and is not accurately conveyed to the press die 3. In contrast, in this embodiment, as described above, the hot slab 1 is tilted. Pinch rolls 2a, 2 with stop cylinders 8a, 8b
Since b is suppressed, no tilting due to gap G occurs,
Accurate transport of hot slabs is possible.

。Next, during the width pressing of the hot slab 1 by the press mold 3, the circuit switching valve 10.11 is returned to the neutral position, and the pressing of the pinch roll 2a by the lifting cylinder 5 is controlled by the force and vibration of the steady rest cylinders 8a, 8b. Release the stopping power. This results in
Since the resistance at the pinch roll pressing portion of the hot slab 1 is reduced, the hot slab is prevented from being rubbed and damaged by the pressing portion due to impact vibrations generated during width pressing. Furthermore, damage to the pinch rolls 2a and 2b is also prevented. Furthermore, when the impact vibration occurs, the pinch rolls 2a, 2b,
The load on the conveying equipment such as the bearings jL4a and 4b, the lifting cylinder 5, and the steady rest cylinders 8a and 8b is reduced. In this way, the transport device is protected from shock vibrations.
