Abstract

PURPOSE:To improve the wear resistance on the surface of a back-up roll by providing the surface of a back-up roll corresponding to a rotary brush with a hard film by thermal spraying at the time of cleaning the surface of a metallic steel strip by the rotary brush. CONSTITUTION:At the time of annealing a cold rolled steel sheet or the like, iron powder, etc., on the surface of a steel sheet 4 continuously moving by the rotation of a brush roll 1 are removed for the purpose of cleaning the surface of the steel sheet 4. At this time, a back-up roll 2 is arranged at the position corresponding to the brush roll 1 with the steel sheet 4 held therebetween to make better the contact of the brush roll 1 with the steel sheet 4 and to increase the cleaning effect by the brush roll 1. The surface of the back-up roll 2 to be used is thermal-sprayed with an Ni-base or Ni-Cr base self-fluxing allay or hard ceramics such as Al2O3 to form a hard film, by which the wear resistance on the surface of the back-up roll can be improved, its service life can be prolonged and its productivity can be improved.

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.

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 ).

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.

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.
