  • the wiping portion since the wiping portion extends in a direction inclined with respect to the plate width direction, the liquid removed from the surface of the strip by the wiping portion and the foreign substances contained in the liquid are removed from the wiping portion. It is less likely to stay upstream, and is more likely to be discharged toward the side of the strip along the slanted wiping portion. Therefore, according to the above configuration (8), foreign matter contained in the liquid (solid matter mixed in the coolant (metal powder, etc. generated by abrasion of the rolling rolls and strips, abrasion debris of the wiping portion, etc.)) is discharged. can promote Therefore, it is possible to effectively prevent the surface of the strip from being scratched due to the foreign matter remaining on the upstream side of the wiping portion.
  • the wiping part is a first portion (12A); a second portion (12B) adjacent to the first portion and located downstream of the first portion in the conveying direction of the strip,
  • the inclination angle ( ⁇ 2) of the second portion with respect to the plate width direction is larger than the inclination angle ( ⁇ 1) of the first portion with respect to the plate width direction.
  • the wiping portion In the case of the wiping portion extending in a direction inclined with respect to the plate width direction as in (8) above, the liquid swept by the wiping portion flows along the wiping portion and reaches the vicinity of the downstream portion of the wiping portion. get together. Therefore, the height of the liquid becomes high at this position, and the liquid overflows when the rolling equipment is operated at high speed, and there is a possibility that the liquid may flow out to the downstream side of the wiping section.
  • the wiping portion has a first portion that is inclined with respect to the width direction of the strip, and a second portion that has a larger inclination angle with respect to the width direction of the strip than the first portion.
  • the liquid collected in the vicinity of the downstream end of the first portion is easily discharged toward the second portion located further downstream. Therefore, it is possible to prevent the liquid from overflowing in the wiping portion and flowing out to the downstream side. Therefore, it is possible to effectively suppress the deterioration of the product quality of the strip.
  • the wiping device in the configuration of any one of (1) to (9) above, a holding part (40) for holding the plurality of split members; An elastic member (60) provided between at least one of the plurality of divided members and the holding portion and capable of applying a biasing force toward the band plate to the at least one of the plurality of divided members. and, Prepare.
  • the thickness of the strip may not be completely constant in the width direction, and may have a certain degree of distribution.
  • at least one of the plurality of divided members arranged in the plate width direction is biased toward the band plate by the elastic member provided between the divided member and the holding portion. be. Therefore, even if there is a distribution in the thickness of the strip, the dividing member is biased by the elastic member to adjust the position in the height direction, and the strip at each position in the width direction can be adjusted. pressed against the surface of Therefore, wiping unevenness in the sheet width direction can be effectively suppressed.
  • the wiping device pressing for applying to at least one of the plurality of split members a pressing force directed toward the holding portion along a direction perpendicular to the extending direction in plan view to at least one of the plurality of split members; having a department, said at least one of said plurality of split members, a side surface (18) extending along the extending direction in plan view; a concave portion (26) provided so as to be concave from the side surface and extending along the vertical direction; The pressing portion is configured to press against the bottom surface (28) of the recess.
  • the bottom surface of the recess provided on the side surface of the split member has an inclined surface that is inclined with respect to the extending direction of the wiping portion in a plan view, and the pressing portion presses the bottom surface. Therefore, since the gap between the end faces of the split members is narrowed, leakage of liquid through the gap can be effectively suppressed.
  • the concave portion provided on the side surface of the split member extends along the vertical direction, the concave portion can guide the vertical movement of the pressing portion with respect to the split member. Therefore, the dividing member can be smoothly moved up and down according to the thickness of the band plate while applying the pressing force of the pressing portion to the dividing member.
  • the rolling facility (1) is rolling rolls (2) for rolling metal strips;
  • the wiping device (10) according to any one of (1) to (11) above, which is provided downstream of the rolling rolls in the conveying direction of the strip; Prepare.
  • the wiping portion that contacts the rolled surface of the strip during wiping includes a plurality of divided members, if any of the divided members is damaged, the wiping portion will not be damaged. replacement (replacement of only the split member that has been damaged or the like) is possible. Therefore, the maintenance cost of the wiping device can be reduced.
