Description

Brush roll manufacturing method

The present invention relates to a method for manufacturing a brush roll.

In general, as a method for producing strips directly from the molten metal, a twin-roll type is used in which the molten metal is supplied between a pair of cooling rolls arranged at a required interval in the horizontal direction and the solidified metal is fed as a strip-shaped thin plate. Although continuous casting equipment is used, with the accumulation of operation time, oxides containing manganese (Mn), silicon (Si), etc. adhere to the outer peripheral surface of the cooling roll, and these oxide adhesion layers When the thickness increases, heat transfer from the molten steel to the cooling roll is hindered, and the growth of the solidified shell on the outer peripheral surface of the cooling roll is suppressed.

Therefore, a cylindrical brush roll that is in contact with the cooling roll over the entire length in the axial direction of the outer circumferential surface is arranged, and the brush roll is rotated in the same direction as the cooling roll to perform the cleaning of the outer circumferential face of the cooling roll. Then, the oxide adhesion layer is removed.

In the case of the conventional brush roll, the brush piece is planted over the entire length so that the bristle body folded in half so as to embrace the bar material is sandwiched inside the straight channel-shaped brush holding member. The brush holding member is formed, and the brush holding member is tightly wound in the axial direction of the cylindrical roll body member without gaps and is fixed by welding or the like, and the densely-implanted brush produced in this way Roles have been mainly used.

However, in the densely flocked type brush roll, the elastic deformation of each hair body is not utilized, and the followability to the outer peripheral surface of the cooling roll becomes poor, and there is a case where sufficient polishing performance cannot be exhibited.

Therefore, as described above, instead of winding the brush holding member tightly in the axial direction of the cylindrical roll body member and fixing it by welding or the like, the brush holding member is formed in a gentle spiral shape with respect to the roll body member. It is possible to make use of the elastic deformation of each hair body by winding and fixing by welding or the like, to improve the followability to the outer peripheral surface of the cooling roll, and to exhibit sufficient scouring performance. Has been proposed by.

In addition, although it is not a brush roll for sharpening the outer peripheral surface of the cooling roll of a twin roll type continuous casting apparatus, as what shows the general technical level of the brush roll relevant to this,

However, as described above, when the channel-shaped brush holding member extending straight is wound around the roll drum member in a gentle spiral shape, the brush holding member is wound tightly in the axial direction of the roll drum member without gaps. As the twist of the brush holding member increases, deformation occurs, and in some cases, the brush piece may fall off.

In view of such circumstances, the present invention can manufacture a brush roll in which a brush piece is disposed in a spiral shape without twisting the brush holding member and without causing deformation due to the twist. It is an object of the present invention to provide a method for manufacturing a brush roll that can prevent the falling off of the brush.

The present invention prepares in advance a plurality of annular brush holding members in which brush pieces are planted at equal intervals in the circumferential direction, and each brush holding member is externally fixed by shifting the circumferential direction position with respect to the roll body member. Thus, the present invention relates to a method for manufacturing a brush roll, characterized in that a brush roll is manufactured so that the brush pieces continuous in the axial direction of the roll body member are arranged in a plurality of spirals.

According to the above means, the following actions can be obtained.

As described above, a plurality of annular brush holding members in which brush pieces are planted at equal intervals in the circumferential direction are prepared in advance, and each brush holding member is fitted and fixed by shifting the circumferential position with respect to the roll body member. Thus, when the brush roll is manufactured so that the brush pieces continuous in the axial direction of the roll drum member are arranged in a plurality of spirals, the channel-like brush holding member extending straight as in the conventional case is used. Unlike winding the member in a gentle spiral, the annular brush holding member is not twisted, deformation due to the twist does not occur, and there is no fear that the brush piece will fall off.

In the brush roll manufacturing method, positioning means for engaging each other may be provided between the brush holding members and the roll drum member, so that the circumferential positions of the brush holding members are shifted with respect to the roll drum member. Therefore, it is preferable to perform the outer fitting and fixing work more efficiently.

The positioning means includes
Convex portions projecting from either the inner peripheral surface of each brush holding member or the outer peripheral surface of the roll body member;
It can comprise from the inner peripheral surface of each said brush holding member and the concave groove provided in any other one of the outer peripheral surfaces of a roll trunk | drum member.

In this case, the convex portion can be formed on the outer peripheral surface of the roll body member so as to extend linearly in the axial direction, and the concave groove can be formed on the inner peripheral surface of each brush holding member while shifting the circumferential position. .

The convex portion may be formed on the outer peripheral surface of the roll body member so as to extend spirally in the axial direction, and the concave groove may be formed at the same circumferential position on the inner peripheral surface of each brush holding member. In addition to making it easier to manufacture and manage each brush holding member, there is no need to worry about the order in which each brush holding member is externally fitted and fixed to the roll body member. It becomes very effective.

On the other hand, the concave groove may be formed on the outer peripheral surface of the roll body member so as to extend linearly in the axial direction, and the convex portion may be formed on the inner peripheral surface of each brush holding member by shifting the circumferential position.

The concave groove may be formed on the outer peripheral surface of the roll body member so as to extend spirally in the axial direction, and the convex portion may be formed at the same circumferential position on the inner peripheral surface of each brush holding member. In addition to making it easier to manufacture and manage each brush holding member, there is no need to worry about the order in which each brush holding member is externally fitted and fixed to the roll body member. It becomes very effective.

According to the method for manufacturing a brush roll of the present invention, a brush roll in which brush pieces are arranged in a spiral shape can be manufactured without eliminating the twist of the brush holding member and causing deformation due to the twist. An excellent effect of preventing the piece from falling off can be obtained.
