It is possible to shear without stopping the transportation of the slab or rolled material. That is, since it is possible to shear the object to be sheared such as a slab or a rolled material during transportation without stopping, it is possible to suppress a temperature decrease due to heat radiation. The running shearing machine 3 is a reversible type capable of shearing in both the forward direction of the rough rolling mill 2 to the finish rolling mill 4 and the reverse direction of the finishing rolling mill 4 to the reverse direction of the rough rolling mill 2. The rolling material transverse feed device 8 is provided between the running shears 3 and the final stand of the rough rolling mill 2.

Specifically, between the final stand of the rough rolling mill 2 and the first stand of the finish rolling mill 4, the running shear 3 is provided on the finish rolling mill 4 side from the center thereof.

る。The finish rolling mill 4 is a reversible rolling mill, and a winding machine with a heat-retaining furnace is provided on the inlet side and the outlet side thereof, and the Steckel type rolling mill is applied. The heat retaining means of the winder with the heat retaining furnace can appropriately maintain the temperature of the winding material or heat it to a desired temperature. By using such a Steckel-type rolling mill, especially when rolling the coil material, the equipment is smaller than the tandem-type rolling equipment, and it is possible to provide a rolling equipment suitable for high-mix low-volume production.

断装置に届く。By providing the running shear 3 on the side of the finish rolling mill 4, it is not necessary to increase the blade interval of the shearing device, and it is possible to prevent the shearing device from becoming complicated and large. That is, when the running shear 3 is provided on the rough rolling mill 2 side,
When passing the slab material 14 that does not need to be sheared through the running shearing machine 3, it is necessary to widen the blade interval of the shearing device,
The shearing device becomes large and complicated. However, by arranging the slab far from the rough rolling mill 2, the shear slab does not reach the shearing device in the thick slab state, and the shearing device reaches the shearing device in the thin state after rough rolling to some extent.
【００２０】そのため、剪断装置の刃物間隔を広くする

た板材の移動回数が少なく、作業効率が良い。Therefore, since it is not necessary to widen the blade interval of the shearing device, the shearing device can be downsized and simplified. Further, since the shearing device is close to the finish rolling mill 4, the number of times the manufactured plate material is moved is small and work efficiency is good.

A running shear 3 is provided between the rough rolling mill 2 and the finish rolling mill 4 on the finish rolling mill 4 side. Further, a rolled material transverse feed device 8 is arranged on the entrance side of the running shears 3, that is, between the rough rolling mill 2 and the running shears 3.

とすることができる。Further, by arranging the second line (thick plate production line) in parallel with the first line, it becomes possible to shorten the equipment length. Further, by making the conveying direction of the second line (thick plate production line) and the conveying direction of the first line opposite to each other, it is possible to easily arrange them in parallel. It has been conventionally considered that it is difficult to arrange another line in parallel on the driving side or the operating side of the first line. The reason is that it is difficult to install the drive line on another line because it is an obstacle on the drive side, and it is difficult to install another line on the operation side because the roll changing device, the shear blade changing device, and the like get in the way. In this embodiment, the drive side of the rough rolling mill 2 in the first line is particularly focused. Generally, the work roll diameter for rough rolling is large, and the work roll diameter for finish rolling is small. Therefore, the vertical spindle distance of the vertical work roll drive for the rough rolling equipment is wide, and the vertical spindle spacing of the vertical work roll drive for the finish rolling equipment is narrow. In other words, in the finish rolling equipment, the vertical spindle interval is narrow and it is difficult to install another line. However, in the rough rolling equipment, the vertical spindle interval is wide, and another line can be installed by passing another line through the clearance. Thus, by utilizing the upper and lower spindle gaps of the rough rolling equipment, the second line can be arranged in parallel near the first line. That is, the second line can be arranged close to the first line between the rough rolling mill 2 and the rough rolling mill drive motor 12, and the installation area of the equipment can be reduced. In other words, if the second line is arranged in parallel from the position of the rolling material transverse feed device 8 to the driving side of the equipment of the first line in the same direction as the conveying direction of the first line, the running shearing machine 3 is driven. Section, the drive unit of the winder 5, the finish rolling mill drive motor 13 that is the drive unit of the finish rolling mill 4, the drive unit of the winder 6, and the like interfere with the second line, and the Line cannot be placed. In the present embodiment, as shown in FIG. 2, this thick plate production line (second line) can be installed between the rough rolling mill 2 and the rough rolling mill drive motor 12, and the thick plate production line is installed side by side. However, the entire width of the equipment can be made almost the same as the equipment for producing only the coil material.

Can be almost the same as the facility for producing only coil material.

In the heating furnace 1, the slab material 14 carried in from the upstream process is heated to a temperature suitable for hot rolling. Since this heating requires time, generally a plurality of slab materials 14 are stocked. And FIG.

The rolling operation reduces the plate thickness of the rolled material and increases the total length thereof. In this embodiment, the maximum dimension of the slab material 14 is 100 mm in thickness and 12 m in length. Further, the rough rolling mill 2 reciprocally rolls to a plate thickness of 30 mm. The length of the rolled material after the rough rolling is 40 m, and the table between the heating furnace 1 and the rough rolling mill 2 needs to be 40 m or more.

返す。Next, in the finish rolling mill 4, as the hot-rolled material, finish rolling is performed once or plural times until a desired sheet thickness is obtained. At the stage of finish rolling, the length of the rolled material is extremely long. For example, when the above slab material is rolled to a plate thickness of 3 mm, the total length is about 400 m. In order to reduce the number of finish rolling mills and downsize the equipment, it is desirable to perform reversible rolling similarly to the rough rolling mills, but it is not realistic to provide such a long table. Therefore, in this equipment, as shown in FIG. 4C, a winding machine 5 and a winding machine 6 are provided before and after the finish rolling machine. When rolling is required a plurality of times, the rolled material that has passed through the finish rolling mill 4 is temporarily finished by the finish rolling mill 4
Take up with the winder 6 at the rear. After finishing the first finish rolling, the finish rolling machine 4 and the winding machine 6 are reversed. The rolled material unwound from the winding machine 6 is rolled by the finish rolling machine 4 for the second time, and wound by the winding machine 5 in front of the finishing rolling machine 4. The same rolling operation is repeated until the desired plate thickness is obtained.

Depending on the number of times of rolling, a so-called up coiler without a heat retention furnace may be used. Further, the attached heat-retaining furnace here is preferably provided with a means for not only heat-retaining the rolled material to be wound but also heating it.

コイル材製造が容易である。As described above, since the rough rolling mill, the shearing machine and the finishing rolling mill are arranged in this order, it is easy to manufacture a coil material of a relatively thin plate material.

薄い厚板の複数枚生産（２−３）である。(2) The case of manufacturing a thick plate will be described below. When a thick plate is produced, the manufacturing method is roughly classified into three types depending on the dimensions of the slab material and the dimensions of the thick plate to be produced. These three ways are the production of one thick plate (2-
1), production of a plurality of relatively thick plates (2-2) and production of a plurality of relatively thin plates (2-3).

程度であり、その厚さはおおよそ２６〜６０mmである。In the case of producing one thick plate from one slab material, after the rough rolling is completed, the rolled material traverse device 8 provided between the rough rolling machine 2 and the running shear 3 is provided. Transport to. After that, the thick plate can be taken out by the rolled material lateral feeding device 8. Generally, the length of one slab is 2.5m to 30m.
The thickness is about 26 to 60 mm.

い。Further, a thick plate production line (second line) from the rolled material transverse feeding device 8 may be used. In addition, if a straightening machine 9, a plate shearing machine 10 and a plate take-out section 11 provided in the second line and a heat treatment device, a cleaning device, etc., which are not shown in the figure, are applied, the plate production Energy consumption associated with reheating and transportation is reduced. If necessary, the thick plate shearing machine 10 may shear the front and rear ends of the rolled material.

備の小型化が図れる。The rolling roll is moved for adjusting the roll interval and the like. Therefore, the spindle that connects the rolling mill drive motor 12 and the rolling roll needs to have a length that allows the coupling to absorb an error. Generally, the distance between the rolling mill and the rolling mill drive motor 12 is sufficiently larger than the entire width of the rolled material. Therefore, this thick plate production line can be installed between the rolling mill and the rolling mill drive motor 12.
In other words, even if a thick plate production line is installed side by side, the overall width of the equipment can be made almost the same as the equipment that produces only coil material, and the equipment can be downsized.

If installed further, the total length of the equipment can be made almost the same as the equipment for producing only the coil material. That is, the equipment length can be shortened as compared with the conventional equipment for producing both thick plates and coil materials.

剪断機３の設備が簡略化及び小型化が可能である。Further, if the running shear 3 is installed on the finishing rolling mill 4, a rolled material having a thick plate thickness and a short overall length immediately after the start of rough rolling can be moved up to the running shear 3 even if it reciprocates on the table. Since it does not reach, the distance between the upper and lower blades of the running shearing machine 3 may be small. That is, the equipment of the running shearing machine 3, which is a shearing device, can be simplified and downsized.

After the rough rolling is completed, the rolled material can be conveyed to the rolled material lateral feeding device 8 and taken out sequentially. In addition, the rolled material is fed from the transverse feed device 8 to the second line, and is sequentially sheared to a desired length by the thick plate shearing machine 10 provided in the second line, so that a relatively thick thickness is obtained. Multiple boards can be obtained.
