Adjusting Crown Roller Loading Adjustment Method and Adjustment Crown Roller

摘要

The present invention relates to a method of adjusting the loading of an adjusting crown roll having a fixed roll axis mounted around it so that the roll mantle is rotated, wherein the nip is formed with the backup roll. The deformation of the roll mantle and / or the linear load in the nip is adjusted by the back-up zone and the loading element supported on the roll axis and acting on the inner side of the roll mantle in the direction of the nip plane. The total resultant force is generated on the inner side of the roll mandrel of the roll by the backup zone (s) to act on the nip plane in the actual opposite direction to the force generated by the loading element and to act on the inner side of the roll mandrel by the backup zone The applied force effect is applied to more than one point and tested in the circumferential direction. The adjustment crown roll includes a fixed roll formed around the roll mantle to form a nip with the backup roll, a loading element and a backup zone disposed between the roll mantle and the roll shaft to act on the inner surface of the roll mantle, And is supported on the axis. The back-up zone supported on the roll axis is formed by at least two rows of back-up zone elements, or by at least one row of back-up chamber elements or back-up chambers. The total resultant force generated in the nip plane by the element or sinker is in fact the opposite direction to the force generated by the heat of the loading element.
