The gap X 3 between the 3 , 3-4 and the mandrel 2 is set equal to the thickness of the hot-rolled steel strip 1. The hot-rolled steel strip 1 has an arrow A.
When entering the gap X 3 from the direction, blocker roll 3
-1, and each blocker roll 3-2 thru | or 3-4 in the state which pressed the hot-rolled steel strip 1 to the mandrel 2, and made the rotation speed of a blocker roll and a mandrel faster than the moving speed of the hot-rolled steel strip 1. Send out hot rolled steel strip. The hot-rolled steel strip 1 sent out is kept in the gap X 4 , X between the winding guide and the mandrel until it is bitten by the next blocker roll.

うまくいかなくなり、ガイド詰りを発生する。(Problems to be solved by the invention) If the gaps X 4 , X 5-1 to X 5-3 are too narrow, scratches frequently occur on the surface of the hot-rolled steel strip 1, and sometimes hot-rolled steel The band is clogged with guides. On the other hand, if the gap is too large, the guide effect will be weakened, so that feeding to the next blocker roll or the like will not be successful and guide clogging will occur.

-1,3-2,3-3,3-4, winding guide 4-1,4-2,5-1,5-
When the tip E of the hot-rolled steel strip 1 passes through the blocker roll 3-4 and enters the second roll, which is wound on the mandrel 2 at 2, 5-3 [see FIG. 4 (a)], The tip E is caught by the winding guide 5-3 in the figure. This winding guide 5-3
When the hot-rolled steel strip 1 is thickened and the winding diameter is increased, the surface of the winding guide is rubbed and scratches are generated, so the gap X 5-3 is set to a relatively large value. However, when the amount of winding increases and the hot-rolled steel strip 1 winds up, it eventually comes into contact with the winding guide. Therefore, when a certain winding diameter is reached, the rolling cylinder 9-3 causes the winding guide 5 to move. Open -3. At this time, the winding guide rotates about the pin 8-3, and the tip C is rotated. Therefore, it is necessary to rotate the tip C so as not to contact the pass line L of the hot-rolled steel strip 1.
For that purpose, it is necessary to reduce the distance between the pin 8-3 and the tip C. That is, the gap X 5-3 of the winding guide 5-3 is relatively large, and the tip C needs to be separated from the biting point D (see FIG. 3) of the second roll of the hot-rolled steel strip 1. This is a completely opposite procedure for the purpose of guiding the tip E of the hot-rolled steel strip 1 and feeding the hot-rolled steel strip 1 to the biting point D of the second roll without slack.

る。Therefore, in the conventional winding method, as shown in FIG. 4 (b), gaps x and y are generated between the hot-rolled steel strip 1 and the mandrel 2 even after the second winding. This state continues up to about the 5th to 10th rolls, and during this period, scratches are generated on the surface of the steel strip due to the winding shift between the steel strips and the winding shift between the steel strip and the mandrel. Further, it takes 5 to 10 windings to shrink the steel strip, so that the inner winding shape of the hot rolled steel strip deteriorates during this period.

に基き説明する。The prior art (Japanese Patent Laid-Open No. 58-215220) discloses a winding device in which a blocker roll and a winding guide are provided on the outer periphery of a mandrel in order to solve the above-mentioned problems. On the other hand, it is proposed to eject a fluid and press the hot-rolled steel strip against the mandrel to wind it. This prior art will be described based on an example of the apparatus shown in FIGS. 6 to 8.

And the winding guides 4-1, 4-2 and 5-1 to 5-3 are installed in the same manner as in the conventional blocker roll 3 respectively.
It is installed between -1 and 3-4. The winding guide has a larger gap with respect to the mandrel than in the conventional case. Winding guide 4
-1 is provided with a fluid chamber 11 inside as shown in FIGS.
Fluid conduits 12, 12 'are attached to both sides to introduce a fluid such as water or air. Then, a large number of slits 13 are provided on the surface facing the mandrel 2 so as to be parallel to the longitudinal direction, and the fluid is jetted perpendicularly to the hot rolled steel strip 1 from the slits 13 so that the hot rolled steel strip 1 is Press on 2 and wind.

みが発生する。In the prior art, it becomes possible to effectively press the first roll of the steel strip against the mandrel 2 by the fluid, and the winding defect is reduced. However, in the prior art, as shown in FIG. 8, the tip of the first strip 1-1 of the steel strip and the second strip 1-2 also form a triangular zone such as X. As a result, gaps x and y as shown in FIG. 4 (b) are generated, and the friction between the first winding 1-1 and the second winding 1-2 is large, so it takes time to eliminate x and y. Takes up and loosening occurs.

発生する内巻形状不良が発生している。Slip between steel strips always occurs, and therefore, slippage occurs between steel strips due to slippage between steel strips when tightly wound.
Further, slippage occurs between the steel strips, and it takes 4 to 8 turns until the looseness of the steel strips is completely eliminated, and in the meanwhile, the inner winding shape defect caused by the looseness occurs.

とんど発生しない。The method of the present invention comprises a blocker roll 3-1 and a mandrel 2
The gap between the hot-rolled steel strips is set larger than the plate thickness of the number of turns after the hot-rolled steel strips overlap, and the tip of the first roll 1-1 of the hot-rolled steel strip and the second roll 1-2.
From the noise attached to the winding guide 5-3 at the portion Y corresponding to the beginning of overlapping, the fluid is jetted almost parallel to the traveling direction of the hot-rolled steel strip, and the first roll 1-1 is strongly pressed against the mandrel 2. The second roll 1-2 is strongly pressed against the blocker roll 3-1 to realize a state in which a high-pressure fluid is interposed between the first roll 1-1 and the second roll 1-2 Y. By realizing the above state, the second roll is a blocker roll 3-
It is strongly pressed against 1, and the portion Y between the first and second rolls is kept at a high pressure so that the tip of the first roll 1-1 is pressed firmly against the mandrel 2 and the first roll 1-1 is securely attached to the mandrel. Wrap around. Also, since the fluid is present between the first and second rolls 1-1 and 1-2, the friction is close to zero, and the second and subsequent rolls are smoothly wrapped and due to the slip between the hot-rolled steel strips. Almost no scratches occur.

た。In the conventional type winding method, the inventors complete the present invention by observing the winding behavior of the steel strip by photographing the moment when the tip of the hot-rolled steel strip is wrapped around the mandrel 2 with a high-speed camera. It is a thing. That is, it is possible to effectively realize the winding of the tip of the hot-rolled steel strip by injecting the fluid onto the Y portion, and the fluid is applied to the hot-rolled steel strip from the winding guide arranged on the outer periphery of the mandrel in the prior art. It was found that there is no need to inject. In the prior art, the peripheral speed of the blocker roll around the mandrel is slightly larger than the traveling speed of the hot rolled steel strip even if the fluid is not ejected from the winding guide to the hot rolled steel strip and the hot rolled steel strip is pressed against the mandrel. It was confirmed that it is possible to make the hot rolled steel strip along the mandrel by setting it.

The position of the tip of the hot-rolled steel strip 1 is calculated by the controller 18 based on the signal from the steel strip detector 16 and the signal from the rotation detector 15 of the pinch roll 14. Also,
Vibration detectors 17-1, 17-2 attached to blocker roll 3,
The passage of the tip of the hot-rolled steel strip 1 is detected by the signals 17-3 and 17-4, and the position calculation accuracy of the tip of the hot-rolled steel strip 1 is improved.

するからである。The fluid pressure is preferably 0.5-10 Kg / cm 2 ,
Different pressures are applied depending on the winding temperature. When the pressure in this case is less than 0.5 Kg / cm 2, the effect of pressing the hot rolled strip to mandrel decreases, the pressure is saturated, the effect is 10 Kg / cm 2 greater, and in terms of strength of the excessive facilities Because it reaches the limit.
