Abstract

(57) [Summary] [Purpose] To prevent the edges and tails of the strip from rising without damaging the edges of the strip. In a side guide device 10 for a strip 1 in which a pair of left and right vertical rolls 12 are arranged on both sides of a strip passing area in a hot rolling line, a reverse cone in which each vertical roll 12 expands upward. It has a trapezoidal shape.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a side guide device for guiding a strip in a strip passing area of a hot rolling line.

[0002]

[Prior Art]

 Conventionally, a side guide device provided on the inlet side of a hot finish rolling mill uses a pair of left and right vertical rolls arranged on both sides of the strip passage area for the purpose of preventing edge scratches and burrs on the strip.

At this time, in the prior art, in order to prevent the strip edge and the tail end from being lifted up, bent, and bent, the axis of the vertical roll 2 is not perpendicular to the plate path (advancing direction) of the strip 1, It is assumed that the strip 1 is inclined 2 to 5 degrees in the traveling direction (see Fig. 3).

In a side guide device for a down coiler, as described in Japanese Utility Model Laid-Open No. 62-101618, guide plates to be installed on both sides of the strip passage area have their upper parts at the bottom. It is also proposed that it is inclined toward the strip side.

[0005]

[Problems to be solved by the device]

 However, the conventional technique has the following problems.

In the case where the vertical axis of the vertical roll is inclined 2 to 5 degrees in the traveling direction of the strip, the direction in which the rotational force F of the vertical roll acts on the strip is downward, but the lifting of the strip is increased from the upper side to the mechanical side. It is not enough to prevent it from being lifted up at the strip edge or tail end, and is not enough to prevent it from rising.

When the upper part of the guide plate is tilted to the strip side more than the lower part, the frictional resistance applied to the strip is excessive, and the strip edge is easily pained.

An object of the present invention is to prevent the rising of the edges and tail ends of the strip without damaging the edges of the strip.

[0009]

[Means for Solving the Problems]

 The present invention is a strip side guide device in which a pair of left and right vertical rolls are arranged on both sides of a strip passing area in a hot rolling line, and each vertical roll has an inverted truncated cone shape in which the diameter increases upward. It was made to exist.

[0010]

[Action]

 According to the present invention, there are the following effects.

The pair of left and right vertical rolls each have an inverted truncated cone shape, and the outer diameters of the vertical rolls are expanded upward. Therefore, each vertical roll can mechanically press the rising of the strip from above, and reliably prevent the rising of the strip edge and the tail end.

[0012] In the above case, since each vertical roll is brought into rolling contact with the strip edge, the strip edge is not damaged.

[0013]

【Example】

 1 is a side view showing an embodiment of the present invention, FIG. 2 is a front view of FIG. 1, and FIG. 3 is a schematic view showing a conventional example.

In FIG. 1 and FIG. 2, 1 is a strip, and 10 is a side guide device provided on the inlet side of the hot finish rolling mill 11.

The side guide device 10 has a pair of left and right vertical rolls 12 rotatably arranged on both sides of the strip passing region of the strip 1. Each vertical roll 12 has an inverted truncated cone shape whose diameter increases upward.

In the side guide device 10, three pairs of vertical rolls 12 are arranged, but the number of vertical rolls 12 may be one or more.

Next, the operation of this embodiment will be described.

The pair of left and right vertical rolls 12 are each in the shape of an inverted truncated cone, and the outer diameters thereof are expanded upward. Therefore, each vertical roll 12 can mechanically press the rising of the strip 1 from above, and reliably prevent the rising of the strip edge and the tail end.

At the time of the above, since each vertical roll 12 rolls against the strip edge, the strip edge is not damaged.

The side guide device of the present invention can also be applied to a device installed on the inlet side of a coiler.

[0021]

[Effect of the device]

 As described above, according to the present invention, it is possible to prevent the rising of the edge or the tail end of the strip without damaging the edge of the strip.
