Problems solved by technology

[0016] Therefore, by using only the brush roll 9, the oxides adhering to the outer peripheral surface of the cooling roll 1 near the edge portions in the width direction and near the center portion in the width direction are removed, and the thickness of the oxides increases. Partially corresponding strips 3 have reduced heat removal, resulting in non-uniform heat generation when viewed from the overall width of the strip, and cracks may be found near the edges in the width direction of the surface of the strip 3 and near the center in the width direction, etc.

Embodiment Construction

[0034] Embodiments of the present invention will be described below based on the drawings.

[0035] figure 1 and figure 2 It is an example of the roll polishing device of the present invention, and has: a brush roll 9 facing the entire length of the axial direction of the outer peripheral surface of the cooling roll 1 of the twin-roll casting machine; The cylinder 10 for pushing in the direction of 1; the cylinder 11 for bending to apply force in the direction away from the cooling roller 1 to the above-mentioned neck portion; Auxiliary brush roller 12 which is partially opposed to the other end portion independently; a push cylinder 13 for pressing the neck portion of the auxiliary brush roller 12 in a direction approaching the cooling roller 1 .

[0036] The brush roll 9 is arranged parallel to the cooling roll 1, and is drawn from the roll gap G (refer to Figure 5 ) are in horizontal contact with the outer peripheral surface of the cooling roller 1 .

Abstract

A roll polishing apparatus is provided which can suppress cracks on a strip. Provided are brush rolls 9 which face outer periphery of chilled rolls 1 over axial length of the chilled rolls, respectively, cylinders 10 which urge the brush rolls 9 wholly to the chilled rolls 1, respectively, and cylinders 11 which deform the brush rolls 9 in conformity to crowns of the chilled rolls 1, respectively. By these elements, wires of the brush rolls 9 are uniformly contacted on outer peripheries of the chilled rolls 1 to wipe off oxides adhering to the outer peripheries of the chilled rolls 1.

Description

technical field [0001] The invention relates to a roll polishing device for a twin roll casting machine. Background technique [0002] As a method of directly producing a strip from molten metal, there is a twin-roll continuous casting method in which molten metal is supplied between a pair of horizontally arranged rolls and the solidified metal is fed out in a thin strip shape. [0003] Figure 5 An example of a twin roll casting machine is shown, which has a pair of cooling rolls 1 arranged in a horizontal line and a pair of side weirs 2 attached to the cooling rolls 1 . [0004] The cooling roll 1 is configured such that cooling water circulates therein, and the gap G between the rolls can be adjusted according to the thickness of the strip 3 to be produced. [0005] In addition, the rotation direction and speed of the cooling roll 1 are set so that each outer peripheral surface moves toward the roll gap G from the upper side at a constant speed. [0006] One side weir ...
