The present invention relates to a coiler (COILER) for winding a sheet cast in a strip roll casting machine (STRIP CASTING APPARATUS) to produce ferrous and non-ferrous metals and alloys thereof in the molten metal directly (STRIP), in particular, directly in the molten metal The edge of the thin plate produced by the flash generated at the edge of the cast or the edge mixed skull (SKULL) when the coil is manufactured to produce a coil product after being rolled through a casting roll. A winding device for preventing a wave phenomenon.

In general, the manufacturing method of the strip (STRIP) is to manufacture the slab by the continuous casting method through the molten steel through the tundish, the continuous casting method of manufacturing the slab into a thin plate through rolling and finishing work, and the molten steel directly to the rotating twin-roll casting roll There is a twin-roll thin plate casting method for casting a thin plate directly without the rolling and finishing work of slabs through the roll, the current double-roll type thin plate casting method directly cast the thin plate without going through several processes of continuous casting method As a result, considerable cost reduction can be achieved in terms of cost, and the manufacturing process of sheet metal can be reduced, and thus, many studies have been conducted on such a double roll type sheet casting method.

On the other hand, the twin-roll thin plate casting method as described above is not shown in the drawings, but in outline, the molten steel casting roll through the immersion furnace installed to the lower side of the molten steel storage vessel, that is, the tundish between the two casting rolls rotating at a constant speed When supplied to the molten steel pool formed by and the edge dam, the supplied molten steel is solidified in contact with the casting roll to form a solidification shell to form a cast at the roll contact point by the rotation of the casting roll. The cast steel thus formed is a thin plate cast through a coil line through a discharge line and is produced as a coil product.

However, as shown in FIG. 1, when the thin plate manufactured by the thin plate casting machine is wound through the winding device, the diameter of the edge portion 110 of the coil 100 becomes larger than the diameter of the center portion (BUILD UP). (B) The phenomenon appears.

That is, although not shown in detail in the drawing, the thin plate produced by sheet casting is not made of thin plate through a casting process and a hot rolling process, and is directly made of thin plate through solidification by casting roll directly from molten steel. Flash, edge skull, edge bulging (EDGE BULGING), etc. occur frequently at the edge portion, and as a result, build-up (B) occurs at the edge portion 110 of the coil 100 at the time of winding the sheet. .

Therefore, when the build-up (B) occurs when the thin plate is wound, tensile stress is generated at the edge part 110 due to the difference in coil diameter between the edge part and the center part, and a wave (WAVE) phenomenon occurs at the edge part 110. This causes many problems in the subsequent process or use as a final hot rolled sheet.

On the other hand, one of the most effective way to prevent the build-up (B) of the thin plate coil 100 cast as a twin roll sheet caster without undergoing such a performance and rolling process, trimming the defective portion of the thin plate edge portion 100 It is important to carry out trimming to handle the defective parts of the edges prior to winding the cast sheet, because the conveying speed is very fast and high temperature when the sheet is cast or the casting speed is about 40-100 m / min. It is virtually impossible.

After all, it would be desirable to prevent the edge wave (EDGE WAVE) due to the build-up phenomenon of the thin sheet edge portion during the winding operation, such a winding device is known from US Patent No. 4078739, etc. All are wound using thin mandrels or drums to wind the thin plates, in particular the winders are divided into two to six parts to allow expansion and contraction in the circumferential direction of the drum. (SEGMENT) is used, but since the expansion or contraction amount is always the same in the axial direction when the drum is inflated or contracted since it is an integral type that is not divided in the axial direction of the winding device, the diameter of the drum is always the same as the center part and the edge part, After all, it is not possible to prevent the edge wave caused by the build-up of the thin edge described above.

Therefore, in the case where the cast sheet is directly cast into the sheet without a rolling and rolling process through the twin roll type sheet casting machine, when the cast sheet is wound through the winding apparatus, the drum in the axial direction of the winding apparatus is considered in consideration of the diameter difference according to the build-up of the edge portion thereof. It would be desirable to vary the diameter of.

The present invention has been made in order to improve the various problems as described above, the object of the present invention is to reduce the build-up occurring at the edge of the thin plate coil during the winding operation of the thin plate cast through the twin-roll type sheet casting machine, An object of the present invention is to provide a winding device for preventing edge waves, which can effectively prevent edge waves.

2 and 3, the rear ends of the connecting portions 32 and 42 of the first and second drive shafts 30 and 40, and the first and second rods 26a and 26b, respectively. The front end is formed integrally with each of the bent connecting ends 32a, 42a, 26a 'and 26b', which are engaged with each other via the bushing B, and the connecting ends 26a 'and 26b' of the rod. Are detachably coupled to each rod 26a, 26b via a coupling C.

In addition, FIG. 2 illustrates the drum member 60. The drum member 60 is attached to the drive shafts in front of the apparatus body 10 and is provided in the apparatus body 10. And rotate to drive the drive shafts 40 and 50.

The gear part 60a is connected to a circumferential surface of the drum member 60 to which a drive chain 16 to which the sprocket 14 of the drive motor 12 mounted on the inner bottom of the apparatus body 10 is coupled. Is integrally formed so that the drum member 60 is driven to drive the drive motor 12.

Referring to the operation of the present invention made of the above configuration as follows.

As shown in Figure 1, the segment 50 of the winding device 1 to reduce the build-up (B) phenomenon occurring in the edge portion 110 of the sheet coil 100 cast in a twin-roll type sheet casting machine It is to be shrunk and expanded in multiple stages, and in particular, the front and rear segments 50a and 50b are shrunk and expanded in an opposite direction, that is, in the opposite direction of the build-up B of the coil 100. By reducing the build-up phenomenon, the sheet winding apparatus 1 of the present invention, which prevents the problems caused by the wave phenomenon of the sheet coil 100 which is not subjected to the playing and rolling process, is as follows.

First, as shown in FIGS. 2 and 3, when the driving means installed in the apparatus body 10, ie, the driving motor 12, is operated, the driving chain 16 engaged with the sprocket 14 of the driving motor 12. ) Is fastened to the gear portion 60a of the drum member 60 attached to the inner and outer driving shafts 30 and 40 described later, so that the driving shafts 30 and 40 rotate integrally. It works.

Thus, the segments 50a, 50b, 50c connected as the links 34a, 34b, 34c, 34a ', 34c' to the drive shafts 30, 40 rotate integrally and eventually the In the segments 50, a cast thin plate is wound up and wound up.

Next, looking at the multi-segment segment (50a) (50b) (50c) of the characteristic configuration of the present invention, as shown in Figure 2, the segment 50 of the present invention is divided into three segments of the central segment ( 50b) is formed to have a long length so that a substantial portion of the inner winding portion of the coil 100 is wound tightly, and the segments that contract and expand gradually over time on both sides of the center segment 50b are explained later. 50a) 50c are disposed.

Next, as shown in FIGS. 2 and 3, the piston means 20, which enables forward and backward operations of the drive shafts 30 and 40, is connected to the first and second pistons 20a and 20b. It is configured, which is to separate and advance each of the first and second drive shafts 30 and 40, respectively.

That is, the first and second hydraulic chambers integrally connected to the center and the outside of the support blocks 22a, 22b, and 22c, which are separated into three stages in the apparatus main body 10 and are assembled through the sealing S ( 24a and 24b are integrally formed, and the oil passages 25a and 25b formed through the support blocks 22 are connected to the hydraulic chambers, respectively, and the oil passages 25a and 25b respectively. Is connected to the oil supply pipe (h).

Therefore, although not shown in the drawing, when hydraulic oil is supplied to each oil supply pipe (h) through an inflow unit, oil is supplied to the first and second hydraulic chambers 34a and 34b, and eventually arranged in each of the hydraulic chambers. The first and second pistons 20a and 20b are moved forward or backward depending on the direction of the oil to be supplied.

Meanwhile, as shown in FIGS. 2 and 3, in the first and second pistons 20a and 20b, the first and second rods 26a and 26b extending forward through the support block 22. ) Is integrally formed, and the connecting ends 26a 'and 26b' are connected to the front end of each of the rods 26 through a coupling C, and to the connecting ends 26 '. The connecting ends 32a and 42a integrally formed at the connecting portions 32 and 42 of the first and second driving shafts 30 and 40 are bent to engage with each other through the bushing B.

Therefore, as shown in FIGS. 2 and 3, when the first and second pistons 20a and 20b move forward or backward, the drive shafts 30 and 40 are integrally moved forward or backward through the connection ends. Done.

At this time, the outer end portions 50a 'and 50c' of the front and rear segments 50a and 50c of the segment members 50 are formed as a plurality of links 34a and 34c on the first drive shaft 30. The second drive shaft 40 is integrally connected to the front of the cylindrical connecting portion 42 connected to the front end of the second rod 26b so as to rotate and linearly move, and the second drive shaft 40 ), The inner ends 50a "and 50c" of the front and rear segments 50a and 50c and both ends of the central segment 50b are connected as a plurality of links 34a ', 34c' and 34b. have.

Therefore, when the first driving shaft 30 moves forward and backward, the outer end portions 50a 'and 50c' of the front and rear segments 50a and 50c of the segments may have the first driving shaft (rather than the center segment 50b). 30 is extended or contracted in the down state, and conversely, the inner ends 50a "and 50b" of the segments 50a and 50c are expanded or contracted to the same diameter as the center segment 50b.

Accordingly, the shape of the segment during expansion and contraction of the segment is formed smaller than the diameter of the center at the front and rear ends thereof, so that the build-up at the edge 110 of the coil 100 shown in FIG. The compressive action of the rolled sheet is to compress the front and rear edge parts to reduce the build-up (B) phenomenon.

Meanwhile, although schematically illustrated in FIG. 2, the driving shafts 30 and 40 are driven by the driving motor 12 while the driving shafts 30 and 40 are movable back and forth through the drum member 60. Since the center line of the drive shaft 30 is rotated about the axis, the drive shafts 30 and 40 are slid through the drum member 60 while being rotated through the drum member 60, thereby driving the drive shafts 30 and 40. The bushings between the drums and the drum member 60 are preferably resumed to prevent friction and enable smooth movement.

In addition, the piston blocks 22 are detachably installed in three stages for the operation of the first and second hydraulic chambers 24a and 24b and the assembly of the piston 20 to be tightly fixed integrally as bolts and nuts. And, it is preferable that the sealing (S) is fitted to the contact portion of the support block 22 and the first and second rods (26a, 26b) so that oil does not leak.

In addition, the first drive shaft 30 is formed of a rectangular cross section inserted into the second drive shaft 40, the second drive shaft 40 is the four segments 60 to the outside as the respective link links (34). ) Are connected.

Accordingly, since the present inventors winding device 1 connects the segments to the drive shafts 30 and 40 which are separately driven in two stages, the center side segment 50b is wound in the width direction of the coil and inclined at both sides thereof. Shrinking and expanding segments 50a and 50b allow the coil edge portion to be wound smaller than the diameter at the center, thereby preventing waves due to build-up at the coil edge.

As described above, according to the present invention, the edge wave preventing winding device of the thin plate reduces the build-up generated at the edge portion of the thin plate coil during the winding operation of the thin plate cast through the twin roll type sheet casting machine, thereby effectively preventing the edge wave of the thin plate. Provide the effect.

After all, it is possible to prevent the edge wave caused by the edge build-up of the thin plate coil to prevent problems that may occur in the subsequent process, and to provide an excellent effect of improving the quality of the produced thin plate and the error rate during the manufacturing of the product. .

While the invention has been shown and described with respect to specific embodiments thereof, it will be apparent to those skilled in the art that various changes and modifications can be made without departing from the spirit or scope of the invention as set forth in the claims below. I would like to know that those who have knowledge of
