ルに対応してバックアップロールが配設されている。2. Description of the Related Art When annealing a steel strip produced by cold rolling in an annealing furnace, its surface is electrolytically cleaned at the inlet of this annealing furnace, and its surface is rubbed by a rotating brush roll. The iron powder and the like adhered in the rolling process are removed. In order to run the steel strip against the pressing force of the brush rolls, a backup roll is arranged corresponding to each brush roll.

ケ月程度の連続使用が限度であった。The surface of this backup roll is generally covered with a rubber material or hard chrome plated. However, in the case of the rubber coating, the wear of the portion in direct contact with the brush is remarkable, and in the case of the plating, the wear due to the electrolytic corrosion action occurs, both

いはセラミックスを溶射すると良い。According to the present invention, such an object is achieved by forming a cured coating by thermal spraying on the surface of a backup roll of a rotating brush used for cleaning the surface of a metal strip. .. Particularly, it is preferable to spray a self-fluxing metal or ceramics.

に基づいて本発明の構成を詳細に説明する。DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The construction of the present invention will be described in detail below with reference to specific embodiments shown in the accompanying drawings.

の表面の清浄化が行なわれる（図１参照）。At the entrance of the continuous annealing equipment, there is provided a brush scrubber 3 in which a plurality of pairs of brush rolls 1 and backup rolls 2 are arranged in parallel. Is continuously passed to clean the surface (see FIG. 1).

セラミックスを溶射積層した硬化被膜６が生成されてい
る。As shown in FIG. 2, the backup roll 2 has a Ni-based or Ni--C on the surface of the roll iron core 5.
A cured coating 6 is formed by spray-laminating an r-based self-fluxing alloy or ceramics such as alumina (Al 3 O 3 ).
【００１１】この硬化被膜６の溶射厚みｔは、０．１mm

２．５mmを超えると、実質的に積層が不可能である。The sprayed thickness t of the cured coating 6 is 0.1 mm.
~ 2.5 mm is suitable. That is, if the thickness is less than 0.1 mm, the surface roughness will not be uniform, and the sprayed layer will be too thin to cause early delamination, so the practical strength will not be as high as expected, and if it exceeds 2.5 mm, the laminate will be substantially laminated. It is impossible.

た。As a result of an experiment conducted on rolls coated with such a coating 6 formed by thermal spraying, each of them has a thickness of 0.1 mm for 6 years or more.
It was confirmed that a service life of about 10 years can be expected with 2.5 mm, and it was found that the difference from the conventional product is remarkable.
