롤 표면(최외층)을 경화 덧붙임층이 아닌 용사(thermal spraying)피막으로 형성하는 경우, 용사피막은, 경화용접층보다 내마모성에 뛰어나기 때문에, 롤 크라운양을 경화 덧붙임의 경우와 같게 하면, 장기간 큰 국부면압이 가해져, 용사피막의 열화에 의한 표면 거칠어짐이 문제로 되어 있었다.When the roll surface (outermost layer) is formed of a thermal spraying coating rather than a hardening addition layer, the thermal spray coating is superior in abrasion resistance to the hardened welding layer. Therefore, if the amount of roll crown is the same as that of hardening addition, A large local surface pressure is applied and surface roughness due to deterioration of the thermal sprayed coating has been a problem.

그래서, 본원발명은, 핀치롤, 래퍼롤 등의 열연공장 롤에 국부면압이 가해지는 것을 경감하는 것을 목적으로 한다.Therefore, the present invention aims at alleviating the application of a local surface pressure to a hot rolling mill roll such as a pinch roll or a wrapper roll.

Fig. 4 is a view showing a roll configuration of a hot rolling mill spinning facility.

이하, 본 발명의 실시형태에 대하여 도면을 참조하면서 설명한다. 도 1은 래퍼롤(100)의 개략단면도이다. 이점파선은, 래퍼롤(100)의 중심축을 나타내고 있다. 래퍼롤(100)은 강판을 권취하는 맨드릴(도 4의 맨드릴(4)을 참조)의 주위에 복수 배치되고, 맨드릴에 강판을 누르는 것이다. 래퍼롤(100)은 몸통부(6) 및 축부(7)를 구비한다.BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, embodiments of the present invention will be described with reference to the drawings. 1 is a schematic cross-sectional view of a wrapper roll 100. Fig. The dashed dotted line indicates the central axis of the wrapper roll 100. A plurality of wrapper rolls 100 are arranged around a mandrel (see mandrel 4 in Fig. 4) for winding up a steel sheet, and press the steel plate against the mandrel. The wrapper roll (100) has a body (6) and a shaft (7).

몸통부(6)는 강판과 접촉하여 강판을 맨드릴에 누른다. 몸통부(6)는 기계구조용 탄소강(SC)으로 이루어지고, 원주형상이며 속이 차있다. 몸통부(6) 표면은, 중심축방향 단부측에서 중심축방향 중심측을 향하여 원호 상에 솟아오르는 크라운 형상으로 형성되어 있다. 몸통부(6)의 롤 크라운양(S1)은 3mm 이하로 설정되어 있다. 여기에서, 롤 크라운양(S1)이란, 몸통부(6)에서의 최대 반경(R1)과 최소 내부직경(R2)의 차분, 즉 내부직경 차이를 말하며, 최대 반경(R1)은 몸통부(6)의 중심축방향 중심부에서의 내부직경이고, 최소 반경(R2)은 몸통부(6)의 중심축방향 단부에서의 내부직경이다. 즉, 본 실시형태의 롤 크라운양(S1)은, 롤 표면에 경화 덧붙임재만을 덧붙인 종래의 롤보다 작은 값으로 설정되어 있다.The body 6 contacts the steel plate and presses the steel plate onto the mandrel. The body portion 6 is made of carbon steel (SC) for machine structure, and has a cylindrical shape and a hollow shape. The surface of the body portion 6 is formed in a crown shape rising on an arc from the side of the central axis direction toward the center side in the central axis direction. The roll crown amount S1 of the trunk portion 6 is set to 3 mm or less. The roll crown amount S1 refers to the difference between the maximum radius R1 and the minimum internal diameter R2 in the trunk portion 6, that is, the difference in the internal diameters, and the maximum radius R1 is the difference , And the minimum radius R2 is the inner diameter at the central axial end of the body portion 6. [ That is, the roll crown amount S1 of the present embodiment is set to a value smaller than that of the conventional roll which is provided with only the hardened overhang material on the roll surface.

도 2는 몸통부(6)의 표면의 일부에서의 확대도이다. 몸통부(6)의 표면에는, 경화 덧붙임층(64) 및 용사층(65)으로 이루어지는 피막층이 형성되어 있다. 경화 덧붙임층(60)은 몸통부(6)의 표면에 덧붙임 재료를 덧붙임 용접함으로써 구성되어 있다. 덧붙임 재료는 조직을 마르텐사이트(martensite)화하기 위한 고(高) Cr, Mo, V 등을 함유한 재료를 사용할 수 있다.2 is an enlarged view of a part of the surface of the trunk part 6. Fig. On the surface of the body portion 6, a coating layer composed of a hardening additive layer 64 and a sprayed layer 65 is formed. The curing addition layer (60) is constituted by superimposing a welding material on the surface of the body portion (6). The additional material may be a material containing high Cr, Mo, V, or the like for martensitizing the tissue.

용사층(65)은, 경화 덧붙임층(64) 상에 용사재료를 용사하여 퓨징(fusing)함으로써 형성되어 있다. 용사재료에는, 예를 들어 Ni기, Ni-Cr기 또는 Co기의 합금에 B와 Si를 1%~수% 정도 첨가하여 재료를 이용할 수 있다. 퓨징처리를 행함으로써 경화 덧붙임층(64)과의 밀착력이 높고, 치밀하여 내식성에 뛰어난 용사피막을 형성할 수 있다.The sprayed layer 65 is formed by spraying and fusing a thermal spraying material on the hardening splice layer 64. [ As the spraying material, for example, a material can be used by adding about 1% to about several percent of B and Si to Ni, Ni-Cr or Co group alloy. By performing the fusing treatment, it is possible to form a sprayed coating having high adhesion with the hardening application layer 64 and being dense and excellent in corrosion resistance.

상술한 구성에 따르면, 몸통부(6)의 최외층에 용사층(65)이 형성되어 있으므로, 몸통부(6) 표면을 경화 덧붙임층만으로 구성한 경우보다 강판 통판(通板)시의 마모량을 적게 할 수 있다. 즉, 강판의 그립력에 영향을 미치는 몸통부(6) 표면의 형상을 장기간 유지할 수 있으므로, 권취 형상을 양호하게 유지할 수 있다.According to the above-described configuration, since the sprayed layer 65 is formed on the outermost layer of the body portion 6, the amount of wear during the steel plate through-flow is less than that in the case where the surface of the body portion 6 is composed of only the hardened- can do. That is, since the shape of the surface of the body portion 6 that affects the gripping force of the steel sheet can be maintained for a long time, the wound shape can be well maintained.

또한, 롤 크라운양(S1)이 3mm 이하로 제한되어 있으므로, 강판의 통판시에 용사층(65)에 가해지는 부하가 분산되어, 용사층(65)의 표면 거칠어짐을 방지할 수 있다.In addition, since the roll crown amount S1 is limited to 3 mm or less, the load applied to the sprayed layer 65 at the time of passing the steel sheet is dispersed, and the surface of the sprayed layer 65 can be prevented from being roughened.

(변형예 1)(Modified Example 1)

상술한 실시형태에서는, 래퍼롤(100)의 롤 크라운양(S1)을 3mm 이하로 제한하는 경우에 대하여 설명하였는데, 본 발명은 이것으로 한정되는 것이 아니며, 핀치롤에도 적용할 수 있다. 즉, 본원발명은 마무리 압연기로부터 반송되는 강판을 코일러측으로 방향 전환시켜, 코일러에 권취하는 상측 핀치롤, 하측 핀치롤에도 적용할 수 있다. 이러한 상측 핀치롤 및 하측 핀치롤에 대하여는, 설명을 반복하지 않는다. In the above-described embodiment, the roll crown amount S1 of the wrapper roll 100 is limited to 3 mm or less. However, the present invention is not limited to this and is also applicable to a pinch roll. That is, the present invention can be applied to an upper side pinch roll and a lower side pinch roll which are turned on a coiler by diverting a steel sheet conveyed from a finishing mill to a coiler side. The description of the upper and lower pinch rolls is not repeated.

(변형예 2)(Modified example 2)
