| 摘要 |
The invention relates to a refiner disk segment suitable for use in the manufacture of paper or board, the segment comprising a circumferential segment part of a refiner disk surface, the segment part being delineated by an outer edge (11) forming the outer circumference thereof, an inner edge (12) forming the inner circumference thereof and radially straight ends (13) joining the ends of said portions of the segment inner/outer circumference. The refining disk segment surface has teeth (3, 4) mounted thereon with grooves (5, 8) remaining between said teeth, and at least one ring (2) is formed from said teeth (3, 4) for refining the material to be processed. The teeth (4) of at least one ring (2) are formed by at least one arc portion of a continuously arcuate shape that is oriented forward in the direction of disk rotation so as to impart the exiting material a high radial velocity toward the perimeter (11) of the segment.
