- the nonwoven fabric wiper includes a core portion (36) extending along the width direction of the strip, and a nonwoven fabric (34) attached around the core portion and provided so as to be in contact with the rolling surface of the strip. ,including.
- the first wiper since the nonwoven fabric wiper containing the nonwoven fabric attached around the core portion is provided downstream of the first wiper, the first wiper cannot completely remove the nonwoven fabric from the rolling surface of the strip. Any excess liquid can be removed with a non-woven wiper. Therefore, the liquid can be more reliably removed from the rolling surface of the strip.
- a portion (38) of the core portion adjacent to the nonwoven fabric in the plate thickness direction of the band plate is made of a graphite fiber reinforced resin composite material.
- the portion adjacent to the nonwoven fabric in the plate thickness direction of the band plate is formed of a graphite fiber reinforced resin composite material. Therefore, even if the nonwoven fabric is torn and the core portion is exposed, the portion of the core portion formed of the graphite fiber reinforced resin composite material contacts the band plate, so the band plate is less likely to be damaged. Therefore, even if the non-woven cloth wiper is used, it is possible to effectively prevent the surface of the strip from being scratched.
- the wiping device A second wiper (22) including the wiping member having the flat surface provided so as to be in contact with the end face (Se) of the strip in the plate width direction is provided.
- the second wiper having a flat surface capable of contacting the widthwise end surface of the strip since the second wiper having a flat surface capable of contacting the widthwise end surface of the strip is provided, the liquid adhering to the widthwise end surface of the strip can be effectively removed. be able to. Further, according to the above configuration (9), it is possible to obtain a wiping device that hardly damages the end face in the plate width direction of the metal strip when wiping the end face and that can reduce the frequency of replacement of the wiping member. can.
- the wiping device in the configuration of (9) above, a first wiper including the wiping member having the flat surface facing the rolled surface of the strip; A said 2nd wiper is provided in the downstream of a said 1st wiper with respect to the conveyance direction of the said strip.
- the second wiper for wiping the end surface of the strip in the width direction is provided on the downstream side of the first wiper for wiping the rolling surface of the strip.
- the second wiper can effectively remove the liquid discharged laterally from the rolling surface of the strip by the first wiper and adhering to the end face of the strip.
- the wiping device A pressing portion configured to press the wiping member toward the surface of the strip is provided.
- the pressing portion presses the wiping member toward the surface of the band plate, the wiping member can be reliably brought into contact with the surface of the band plate. Thereby, the liquid on the surface of the strip can be effectively removed.
- the graphite fiber reinforced resin composite material includes a graphite fiber reinforced polyimide resin composite material.
- the surface of the metal strip is less likely to be damaged during wiping of the surface of the metal strip, and the replacement frequency of the wiping member can be reduced.
- the rolling facility (1) according to at least one embodiment of the present invention is rolling rolls (2) for rolling the metal strip (S);
- the wiping member is made of a graphite fiber reinforced resin composite material that has self-lubricating properties and has a small coefficient of friction with metal materials. and wear are less likely to occur. As a result, the replacement frequency of the wiping member can be reduced, and abrasion debris due to wear of the wiping member is less likely to occur, so that the surface of the strip plate can be prevented from being scratched due to the abrasion debris. Further, in the configuration (13) above, since heat and wear due to friction between the wiping member and the strip are less likely to occur, the relatively wide flat surface of the wiping member and the surface of the strip can be brought into contact with each other.
- the wiping member is pressed against the surface of the band plate, and the contact portion between the wiping member and the surface of the band plate is locally exposed. Therefore, it is difficult for unevenness to be formed on the surface of the wiping member. Therefore, partial contact between the surface of the wiping member and the strip is suppressed, and damage to the surface of the strip due to local surface pressure that can be caused by such partial contact is suppressed. be able to. Therefore, according to the configuration (13) above, the surface of the metal strip is less likely to be damaged during wiping of the surface of the metal strip, and the replacement frequency of the wiping member can be reduced.
- expressions such as “in a certain direction”, “along a certain direction”, “parallel”, “perpendicular”, “center”, “concentric” or “coaxial”, etc. express relative or absolute arrangements. represents not only such arrangement strictly, but also the state of being relatively displaced with a tolerance or an angle or distance to the extent that the same function can be obtained.
- expressions such as “identical”, “equal”, and “homogeneous”, which express that things are in the same state not only express the state of being strictly equal, but also have tolerances or differences to the extent that the same function can be obtained. It shall also represent the existing state.
- expressions representing shapes such as a quadrilateral shape and a cylindrical shape not only represent shapes such as a quadrilateral shape and a cylindrical shape in a geometrically strict sense, but also within the range in which the same effect can be obtained. , a shape including an uneven portion, a chamfered portion, and the like.
