Abstract

The invention relates to a rolling plant (100) having a rolling mill stand (102) comprising rolls (104a-b, 106a-b), wherein the rolling plant (100) has a nursing Tool (112a-d), which can be used to mechanically remove dirt from the surface of the rolls (104a-b, 106a-b) during rolling work and the rolling plant (100) also has a driven transport device (114a-d), with which the care tool (112a-d) can be moved during the rolling operation substantially in the longitudinal direction of the roll over the surface of the roll (104a-b, 106a-b). Furthermore, the invention relates to a method for the care of the surface of a roll, wherein dirt, in particular build-up, is mechanically removed from the surface (202) of the roll (104a-b, 106a-b) by means of a care tool (112a-d) , wherein the care tool (112a-d) moves over the surface (202) of the roll (104a-b, 106a-b) substantially in the longitudinal direction of the roll during the removal of dirt and wherein b) Rolling work to remove dirt.

Description

technical field [0001] The invention relates to a rolling installation, in particular for cold rolling aluminum strip, having a rolling stand comprising at least one roll, preferably at least two work rolls and at least two Backup rollers. The invention also relates to a method for caring the surface of rolls, in particular of rolls of a four-high cold rolling mill, preferably for the production of aluminum foils. Background technique [0002] Four-high cold rolling mills are usually used for the production of aluminum sheets and foils. Deposits are thus formed on the back-up and / or work rolls during the rolling process, which deposits can have a significant wear effect. These deposits wear the surface structure of the rolls to such an extent that the rolls have to be replaced frequently. Furthermore, the laminate tends to form patterns and striations which can then be transferred onto the rolled strip or foil and thus impair its surface properties. [0003] A solution t...
