板26とが設備されている。Prior Art At the most downstream position of a thin plate rolling line such as a hot strip mill line, there are a plurality of down coilers, for example, two down coilers as shown in Fig. 1, to alternately wind the hot rolled material. 10 and 12 are installed. Usually, the down coiler 10 at the end of the line is for thick materials with a thickness of 3.2 to 19 mm or high tensile strength materials, and the down coiler 10 upstream from it is
No. 2 is used for thin objects having a thickness of 1 to 12.7 mm, for example. Each of the down coilers 10 and 12 includes a mandrel 14, a wrapper roll 16 that is pressed against the mandrel 14 during winding, and a pinch roll 20 that is positioned in line with a runout table roller 18. This pinch roll consists of an upper pinch roll 20A and a lower pinch roll 20A.
It consists of B. The down coiler further includes a guide 22 provided upstream of the pinch roll,
A deflector 24 and a guide plate 26 are provided on the downstream side thereof.

うにその付属のデイフレクタが上昇位置にある。 The guide 22 is for guiding the rolled material to the pinch rolls 18, and the deflector 24 is for guiding the rolled material to the pinch rolls 18.
In the raised position, the rolled material is guided to the mandrel 14, and in the lowered position, the rolled material is passed further downstream to the down coiler. pinch roll 1
8 serves to deflect the rolled material towards the mandrel 14 and to apply back tension between the rolled material and the mandrel 14 so that the rolled material is tightly wound onto the mandrel 14. In FIG. 1, after the down coiler 10 has wound up the rolled material, the attached deflector is in the raised position so that the down coiler 12 can take up the rolled material.
ダウンコイラによる巻取りのとき、第2図に示
すように、マンドレルとピンチロールとの間と、
ピンチロールとその上流との間とのそれぞれで圧
延材28が緊張状態にあることが理想的である。
これにより、圧延材28を傷付けずに、圧延材2
8を緊密にマンドレルに巻取ることができる。 When winding with a down coiler, as shown in Figure 2, between the mandrel and the pinch roll,
Ideally, the rolled material 28 is under tension between each of the pinch rolls and upstream thereof.
As a result, the rolled material 28 can be removed without damaging the rolled material 28.
8 can be tightly wound onto a mandrel.
この第2図の状態は、薄物の場合ほぼ確実に得

材28がマンドレルに緊密に巻取れなくなる。 The state shown in Figure 2 can almost certainly be obtained in the case of thin materials, but in the case of thick materials or high-tensile materials, the state shown in Figure 2 cannot be achieved with certainty due to the rigidity of the rolled material. First, as shown in Figure 3, the rolled material may swell just before the pinch rolls. If the rolled material swells just before the pinch rolls, the rolled material 28 may be damaged by the guide 22, or sufficient back tension will not act on the rolled material 28, making it impossible for the rolled material 28 to be tightly wound onto the mandrel. .

It is possible to do so. However, these methods require extra equipment, resulting in increased equipment and maintenance costs.

It is designed to wind up the rolled material by applying back tension between it and attached pinch rolls, and at least one of these down coilers, excluding the most upstream down coiler, is for thick or high-quality materials. In down coiler equipment, which is a down coiler for tensile materials, when winding thick materials or high tensile materials, a pinch roll attached to at least one down coiler upstream of the down coiler for thick materials or high tensile materials is also used. There is provided a winding method using a down coiler, which is characterized in that a thick material or high tensile strength material is wound on a down coiler for thick materials or high tensile strength material while applying back tension.

FIG. 9 shows a state in which a thick material or a high tensile strength material is wound up and wound around the mandrel 14. As a result, the downstream down coiler 1
Since not only the pinch roll of the down coiler 0 but also the pinch roll of the down coiler 12 on the upstream side is in a pinch state, the back tension of the two pinch rolls acts on the hot rolled material 28, and the pinch roll The hot-rolled material does not bulge immediately before the hot-rolled material is tightly wound around the mandrel 14. Further, as shown in FIG. 3, the hot rolled material will not be damaged due to swelling of the rolled material just before the pinch rolls.

Pinch roll 20A of upstream down coiler 12
and 20B are separated from each other, however, the pinch rolls 20A and 20B of the down coiler 12 on the upstream side may be brought into contact with each other to create a pinch state when the hot rolled material is bitten.
