Description

레일형 압연재용 압연 스탠드 {ROLL STAND FOR RAILFORM ROLLING STOCK}Rolling stand for rail rolling material {ROLL STAND FOR RAILFORM ROLLING STOCK}

본 발명은 특히 가역 압연을 위하여, 압연재를 그 사이로 유도하는 2개의 구동 롤러 및 각각의 구동 롤러에 결합한 백업 롤러를 포함하는 레일형 압연재용 압연 스탠드에 관한 것이다. 백업 롤러 및 구동 롤러는 각각 인서트(insert)에 장착되고, 백업 롤러에는 드레서(dresser)가 결합되어 있다.The present invention relates, in particular, to a rolling stand for rail-shaped rolling material comprising two drive rollers for guiding the rolled material therebetween and a backup roller coupled to each drive roller, for reversible rolling. The backup roller and the drive roller are mounted on inserts, respectively, and a dresser is coupled to the backup roller.

동일한 종류의 압연 스탠드가 DE 33 27 433 C2에 개시되어 있다.A rolling stand of the same kind is disclosed in DE 33 27 433 C2.

스트립(strip)을 압연하는 경우, 상이한 두께 또는 면적의 스트립을 제조하거나 품질이 상이한 소재를 가공할 수 있으므로, 스트립재(strip stock)의 특성에 상당한 차이가 발생하는 점을 유의해야 한다. 이처럼 차이가 심한 경우, 스트립재의 특성에 차이가 있으면 구동 롤러의 편향(deflection)이 달라지므로, 특히 직경이 비교적 작은 구동 롤러를 사용할 때 영향을 미친다. 이처럼 상이한 편향을 방지하기 위해서는 구동 롤러를 사전에 미리 이에 상응하도록 조정해야 한다.When rolling strips, it should be noted that significant differences occur in the properties of strip stock, as strips of different thicknesses or areas can be produced or materials of different quality can be processed. If the difference is severe, the deflection of the drive roller is different if there is a difference in the characteristics of the strip material, and thus it is particularly affected when a drive roller having a relatively small diameter is used. In order to prevent such a different deflection, the driving roller must be adjusted in advance correspondingly.

DE 33 27 433 C2에는 변위 방향과 반대로 지지하기 위한 구동 롤러에정압(hydrostatic) 지지 부재를 포함하는 지지 장치의 결합에 대하여 개시하고 있다. 지지 장치는 지지되는 면을 향하는 정압 압력 백(bag)을 구비하고, 각각 지지된 구동 롤러의 세로축에 대하여 평행하게 배치되며, 조절 가능한 형태를 가진다. 여기서 백업 롤러는 지지 부재를 이용하여 운반체(carrier) 주위에 지지되는 압연 슬리브(sleeve)를 구비한 편향 조절 롤러로써 작동된다. 구동 롤러는 자신에 결합된 지지 장치와 함께 압연 스탠드에서 압연재의 레일에 평행하게 수평 이동할 수 있다.DE 33 27 433 C2 discloses the coupling of a support device comprising a hydrostatic support member to a drive roller for supporting against the direction of displacement. The support device has a static pressure bag facing the surface to be supported, each of which is arranged parallel to the longitudinal axis of the supported drive roller, and has an adjustable form. The backup roller here operates as a deflection control roller with a rolling sleeve supported around the carrier using a support member. The drive roller can move horizontally parallel to the rail of the rolled material in the rolling stand with the support device coupled thereto.

EP 0 233 597 B1에는 인서트에 장착되어 마찬가지로 수평 이동할 수 있는 구동 롤러가 개시되어 있다. 이 경우에 위치 이동은 핸들바(handlebar) 장치로 이루어진다. 핸들바 장치는 동심원형으로 된 회전핀(swievel pin)으로 유도되어 동작을 제어할 수 있다.EP 0 233 597 B1 discloses a drive roller mounted on the insert and likewise movable horizontally. In this case the positional movement is made with a handlebar device. The handlebar device is guided by a concentric swivel pin to control its operation.

이와 무관하게 EP 0159 796 A1에는 구동 롤러가 압연재의 이동 방향 또는 그 반대 방향으로 편향되도록 영향을 미치는 것에 대하여 개시되어 있다.Regardless, EP 0159 796 A1 discloses that the driving roller influences the deflection in the direction of movement of the rolled material or vice versa.

본 발명의 목적은 구동 롤러의 축이 백업 롤러의 축의 평면으로부터 일탈(offset)하는 것을, 간단한 수단을 이용하여 비교적 큰 영역에서 가능하게 함으로써 차이가 심한 편향을 방지하는 데 있다.It is an object of the present invention to prevent the deviation from being severely biased by allowing the axis of the drive roller to be offset from the plane of the axis of the backup roller in a relatively large area using simple means.

도 1은 선회 가능한 구동 롤러를 구비한 가역 스탠드를 나타낸 도면이다.BRIEF DESCRIPTION OF THE DRAWINGS Fig. 1 shows a reversible stand with a pivotable drive roller.

본 발명의 목적은 특허청구범위 제1항에 기재한 압연 스탠드의 경우, 드레서를 백업 롤러의 인서트에 연결시키고, 드레서에 닿은 조정 수단이 인서트에 장착된구동 롤러를 드레서와 함께 축에 평행하게 백업 롤러의 축 주위로 선회하게 함으로써 달성된다.It is an object of the present invention, in the case of the rolling stand according to claim 1, to connect the dresser to the insert of the backup roller and back up the driving roller with the dresser the adjustment means in contact with the dresser parallel to the shaft with the dresser. This is accomplished by making it pivot about the axis of the roller.

가역 스탠드를 도시한 도 1 및 실시예를 통하여 본 발명을 설명한다.The present invention will be described with reference to FIG. 1 and the embodiment showing a reversible stand.

백업 롤러(1)를 인서트(2)에 장착하며, 유압 실린더(6)에 의하여 백업 롤러(1)는 축 주위를 선회할 수 있다. 잘 알려진 바와 같이, 실린더(14, 15)로 상하의 백업 롤러를 작동시킨다. 상부의 백업 롤러는 실린더(9)로 균형을 맞춘다. 실린더(9)를 실린더 블록(7)에 고정하여, 유압 실린더(6) 및 상부 백업 롤러의 균형을 맞춘다.The backup roller 1 is mounted to the insert 2, and the backup roller 1 can pivot around the shaft by the hydraulic cylinder 6. As is well known, the upper and lower backup rollers are operated by the cylinders 14 and 15. The backup roller at the top is balanced by the cylinder 9. The cylinder 9 is fixed to the cylinder block 7 to balance the hydraulic cylinder 6 and the upper backup roller.

백업 롤러의 인서트(2)를 미끄럼판(sliding pad)(10) 및 마모판(11)에 고정시킨다. 미끄럼판을 마모판(12, 13)에 수직으로 유도한다.The insert 2 of the backup roller is fixed to the sliding pad 10 and the wear plate 11. The sliding plate is led perpendicular to the wear plates 12, 13.

구동 롤러(3)는 구동 롤러 인서트(4)에 장착되고, 구동 롤러 인서트는 백업 롤러 인서트(2)에 고정 연결된 드레서(5)에 연결된다. 실시예에서는 백업 롤러 인서트(2)에 조정 수단(8)을 연결하고, 유압 실린더(6)로 조정 수단(8)을 작동시킨다. 유압 실린더(6)를 이용하면 드레서(5)에 대체로 수평력이 가해질 수 있다. 이 수평력으로 인하여 드레서 및 드레서와 결합된 구동 롤러 인서트(4)가 선회한다. 알 수 있는 바와 같이, 이러한 양쪽 조정 수단을 드레서에 적용함으로써, 드레서는 양 방향에서 축과 평행하게 백업 롤러의 축 주위를 선회할 수 있다. 역회전하는 경우, 구동 롤러의 상이한 편향을 이러한 방법으로 방지할 수 있다.The drive roller 3 is mounted to the drive roller insert 4, and the drive roller insert is connected to the dresser 5 fixedly connected to the backup roller insert 2. In the embodiment, the adjusting means 8 is connected to the backup roller insert 2, and the adjusting means 8 is operated by the hydraulic cylinder 6. The use of the hydraulic cylinder 6 allows a generally horizontal force to be applied to the dresser 5. This horizontal force turns the dresser and drive roller insert 4 coupled with the dresser. As can be seen, by applying both of these adjusting means to the dresser, the dresser can pivot around the axis of the backup roller parallel to the axis in both directions. In the case of reverse rotation, different deflection of the driving roller can be prevented in this way.

본 발명을 통하여 구동 롤러의 축이 백업 롤러의 축의 평면으로부터일탈(offset)하는 것을, 간단한 수단을 이용하여 비교적 큰 영역에서 가능하게 함으로써 차이가 심한 편향을 방지할 수 있다.Through the present invention, the deviation of the drive roller from the plane of the axis of the backup roller can be prevented in a relatively large area by using simple means, thereby preventing a large deviation.
